PLOWING THE INTERNET
As news continues to trickle out concerning the FQPA, we will keep you up to date.
Within a month or so, food tolerances that were pending before FQPA will be withdrawn. Current tolerances will remain, but they will need new petitions to comply with FQPA.
One person out of 10 in the Office of Pesticide Programs is working on FQPA.
An agenda for compliance should be out by the new year. Until then, EPA will provide interim guidance.
Congress has added some money to re-evaluate tolerances.
A food tolerance must be in place before a Section 18 can be issued. This creates a problem since a Sec. 18 has been an exemption from tolerance. EPA recognizes this, however; I think they will try to work with us. EPA can set interim/time-limited tolerances for Section 18's IF the tolerance will meet the stronger health standard of FQPA. Section 18's will now apply to imported food as well.
States can still issue crisis exemptions, BUT if the EPA decides not to issue a interim tolerance, the food could be condemned.
Having a screen for hormone-disrupting pesticides in three years may be a pipe dream. It is not the fault of EPA; this area is full of questions without answers. This problem is not going away, and it is scary because so little is known. You are going to hear 'endocrine disruption' in relationship to everything from pesticides to teething rings.
As EPA considers aggregate exposure to pesticides (from food, around home, etc), they will probably group pesticides with similar modes of action (e.g., group organophosphates together).
Food already in the market pipeline will continue to be sold unless there is some 'unreasonable' risk.
EPA has asked registrants not to submit new food uses for pesticide registrations until FQPA is sorted out, unless the petitions are emergencies, biopesticides, or pass EPA reduced risk screen.FQPA will slow down reregistration.
Talking out of the other side of their mouth, the Feds have eliminated funding for the USDA Pesticide Data Program (PDP). The PDP collects samples of fruits and vegetables eaten primarily by children and analyzes the pesticide residues. Without these data, EPA scientists must calculate theoretical pesticide risks based on assumptions concerning how much pesticides children consume. Assumptions are typically conservative and often overestimate exposure.
When tolerances are allowed based on the pesticide's benefits, the increased risk must be no more than 10 times the level EPA would otherwise allow. Lifetime risk must be no more than twice the normal EPA level. The benefits would have to re-examined within five years.
If EPA chooses not to use the Codex (the international standard) tolerance, the administrator must publish the reasons.
Tolerances for the following pesticides/use sites had been revoked (or were proposed for revocation) under the Delaney clause. The tolerance revocations and the proposals have been withdrawn by EPA. In other words, these pesticides will be able to be used on these crops again until something else happens. Wait for the official word; the FR notice is expected within 10 days.
This action does not mean these pesticides are saved. I expect the FQPA to also catch many of these combinations.

FROM THE COURTROOM
The saga of Benlate goes on. It seems to have all the elements of a good mystery novel. DuPont settled 19 cases in Florida for an undisclosed amount of money. In one suit, the court stated that the company had destroyed evidence and disregarded discovery orders. Apparently, DuPont tried some Benlate in Costa Rica and killed a bunch of tropical plants. The plants were reportedly destroyed and the evidence concealed.
A Vermont law to label BST milk was overturned by federal appeals court. The court ruled that the Vermont law was in response to consumer interest, rather than public health risk. This ruling is a good sign for all of the biotech food products on the market or coming on line.
Dow Chemical won a lawsuit brought against them for allegedly spilling more than 6000 liters of chlorpyrifos (Lorsban) into the Bay of Cartagena (near the country of Columbia), killing millions of fish. More than 500 Columbian fisherman sought lost income. Dow argued that fishing has been banned in the bay since 1977, due to contamination unrelated to the company.
The EPA will offer an opportunity for public comment before extending the time period for sale of existing stocks. When the EPA canceled mevinphos (Phosdrin), they allowed a period for the sale of existing stocks. Then, they extended it without really telling anyone. The United Farm Workers of America took them to court and won this settlement.
The EPA continues to hold meetings on WPS; there are comments on both sides. Greenhouses and ornamental nurseries say they need to get back in the greenhouse/nursery before the REI expires. Other groups point out that mandated PPE can make heat stress a more dangerous concern than pesticides. The Yuma Veg. Shippers say they have spent $100-$700 on decontamination sites for every tractor and irrigator; none of the decontamination facilities have been used. On the other hand, farm worker groups call for stronger enforcement. Workers are reportedly afraid to file any complaints when WPS rules are violated. (Pesticide & Toxic Chemical News, 9-18-96)
The Ga. Dept. of Agriculture has started a new program to help everyone understand how to comply with WPS. GDA is conducting mock WPS inspections for commodity groups to demonstrate what steps are required by WPS. No enforcement action will taken for any WPS violations discovered during these mock inspections. If you are interested in setting up a workshop, give Doug Jones (404-656-4958).
There is some debate about whether amitraz is useful to control tracheal mites. The debate is moot for the time being; there are NO amitraz formulations that are legal for use on honey bees. (APIS, Aug. 1996)

The EPA has announced the final version of health and safety testing guidelines for studies in support of pesticides and industrial chemicals. The new guidelines bring us in harmonization with international guidelines from the Organization of Economic Cooperation and Development (OECD), an international organization including most industrialized countries.
The guidelines tell companies how to do product performance testing, spray drift testing, health effects analysis, etc. If you want more information, write to:

The EPA is seeking public comment on its "Proposed Guidelines for Ecological Risk Assessment," published in the Federal Register on Sept. 9. Ecological risk assessment is a process for organizing and analyzing data, information, assumptions and uncertainties to evaluate the likelihood of adverse ecological effects. Among other things, the analysis is used to make pesticide regulations. The proposed guidelines were designed to improve the quality of EPA's ecological risk assessments and increase the consistency of assessments among the Agency's regional and program offices. Comments are due to the Agency by Dec. 9. I would advise taking a look at the guidelines and offering comments. When I was with EPA, some of the assumptions used to estimate ecological effects were pretty far-fetched.
You can see the guidelines on the Web http://www.epa.gov/ORD/WebPubs/fedreg
Or call Bill van der Schalie at EPA (202-260-4191).
The Consumer Labeling Initiative should improve pesticide labels for homeowners. Here are the highlights of the draft report. (from Pesticide and Toxic Chemical News 8-28-96)
Replace 'inert ingredients' with full disclosure of all contents.
Clearly indicate respiratory effects, skin absorption, and special risks to pregnant women and children.
Indicate potential environmental effects.
Include simple instructions on how to avoid accidents.
Write labels at a 4th or 5th grade reading level.
Write in positive language (e.g., 'Use with ventilation' instead of 'do not breathe fumes'.
If all of this information is added, a 2 oz of product will come with 25 pounds of instructions, which most consumers will immediately throw into the trash.
Agriculture Secretary Dan Glickman has announced members of the newly-created National Agricultural Research, Extension, Education, and Economics Advisory Board. The advisory board will advise the secretary and land-grant colleges and universities on agricultural research, extension, education and economics policy and priorities. It replaces the Agricultural Science and Technology Review Board, the Joint Council on Food and Agricultural Sciences, and the National Agricultural Research and extension Users Advisory Board.
Because the members will have the ear of the Agriculture Secretary, I thought you might want to know who they are. It's not always what you know; sometimes it's who you know.

The board met in September to review of the USDA Research, Education, and Economics Draft strategic Plan; nominate people to the 15-member "Strategic Planning Task Force,"which was created under the FAIR Act to develop a 10-year strategic plan for federally-funded agricultural research facilities; and consultation on other FAIR Act legislation, including implementation of the Fund for Rural America competitive grants program.
The EPA Office of Pesticide Programs (OPP) released a report card on itself recently, in a report called Targeting OPP Customer Service Improvements. The general public, blissful in their ignorance, gave OPP a 'satisfactory or above' in responding to the public, quality of information, and protection of the environment/public health. The public gave them lower grades on access to pesticide information. States were not happy with EPA's telephone responses or the exclusion of states into the early stages of decisions.
Registrants and environmental/public interest groups rated OPP a 4.4 out of 10. No OPP service met expectations. The primary complaints were lack of timely decisions, lack of consistency in policy, and poor telephone responsiveness. The report ends with recommendations to improve telephone responsiveness, timeliness/consistency in decisions, and early inclusion in the decision-making process. Even though EPA brought home an 'F', have a little sympathy. Their job is one the most difficult and thankless in the world. Even so, they could answer the phone.
Here is the latest on the Integrated Pest Management Initiative.
The CSREES budget for the IPM Initiative remained level in FY 1997: IPM research=$2.7 million; IPM extension=$10.8 million; Pest Management Alternatives Program (Emerging Pest and Disease Issues)=$1.6 million; Pest Management Information/Decision Support System=$177,000. IPM-related programs: IR-4=$5.7 million; NAPIAP research=$1.3 million; NAPIAP extension=$3.2 million; Pesticide Applicator Training=$2.1 million; Sustainable Agriculture research=$8.0 million; Sustainable Agriculture extension=$3.3 million; Water Quality=$10.7 million. The requested $8 million budget increase for FY 1997, $4 million for research and $4 million for extension, was not appropriated by Congress. The funding increase would have supported large-scale competitive grants ("Phase II" projects)--up to $500,000 per year for up to 6 years. There are some hints that additional funding may appear. The land-grant system's past and future role in getting IPM implemented is acknowledged as is viewed as a success story at USDA.
Dr. Barry Jacobsen completed his service as the USDA IPM Coordinator on June 30, 1996. Dr. Gerrit Cuperus, Professor of Entomology at Oklahoma State University, will serve as USDA IPM Coordinator from November 1, 1996, to September 30, 1997.
IPM research and extension priority needs for 64 key commodities have been developed by 46 states with the direct involvement of 4267 customers including 3210 farmers. This process has helped develop significant "grassroots" support and high expectations from growers and agribusiness for action. The needs lists are being summarized and will eventually be accessible via the World Wide Web. These priority needs lists are being used to drive the allocation of federal IPM resources available through both formula and competitive channels.
The Pest Management Alternatives Program was created to provide competitive grants to address pest control problems with few or no alternatives to pesticides that may be lost due to regulatory action or pest resistance. In FY 1996, a total of 41 grant proposals were received, and 17 projects totaling $1,502,518 were funded. It is anticipated that the deadline for submission of FY 1997 proposals will be the end of January, and awards made in mid-May 1997.
The four regional IPM grants programs were strengthened with the addition of a new funding category for joint research-extension projects. This was made possible by allocation of special grant research funds and Extension IPM special project funds to this program; USEPA contributed $27,000 per region. In FY 1996, a total of 90 research-only grant proposals were received, and 30 projects (33%) totaling $2,078,979 were funded; and a total of 37 research- extension grant proposals were received, and 13 projects (35%) totaling $905,071 were funded.
The Pest Management Information/Decision Support System (PMIDSS) was created to provide scientists, regulators, decision-makers, and others with sound information on pest management issues. A two-track approach is being taken: 1) Make crop insurance coverage available to growers who participate in large demonstration projects (e.g., the Corn Rootworm Areawide project) starting in the Midwest this year. 2) Provide data to Federal Crop Insurance that farmers who use IPM practices are lower risks and should be in a lower risk pool. Federal Crop Insurance has indicated it will attempt to provide lower rates for growers using defined IPM practices, if it can be demonstrated that these practices lower risk.

EPA has completed a series of regulatory reinvention measures to
speed-up the registration of new, safer insect pheromones. EPA's new common sense measures, a series of rules published between 1993 and 1996, have reduced both the time and cost of bringing new pheromone pesticides to market. Approval
times have been reduced from over two years to as little as two months, contributing to the development and marketing of a record number of safer products mainly used to control moth and caterpillar pests in the past three years.
Specific measures in the new process include exempting most pheromone pesticides from requirements for the establishment of tolerances (maximum permissible levels for residues in food). EPA will also allowing research and testing of most pheromone products to proceed on up to 250 acres of land without requiring prior Agency approval, compared to the 10-acre limit that applies to conventional pesticides.
The recent 11th Scientific Conference of the International Federation of Organic Agriculture Movements (IFOAM) stressed that organic practices are viable
worldwide. Their issued statement demanded that organic agriculture be prioritized as a strategy for creating global food security. The Declaration asserts that organic agriculture can produce sufficient, high quality food to ensure long term food
security while protecting both human health and the environment. Signatories to the Copenhagen Declaration expressed fear that the "failure of the Green Revolution [I didn't realize we had failed] will be repeated by promoting an even more destructive gene-revolution." IFOAM reports that yields in developing countries can be increased by 200%-300% with organic practices. IFOAM represents 530 farmer, food security and consumer organizations worldwide.
Sales of U.S. organic products in 1995 increased 22% over 1994 figures, according to Natural Foods Merchandiser (NFM), marking the 6th year of 20%+ growth. Organic sales increased from US$2.31 billion in 1994 to US$2.8 billion in 1995. Contributing factors include a widening consumer base, expansion by natural products retailers, greater mainstream acceptance and increasing organic acreage. Natural product stores led the U.S. organic market with $1.87 billion in sales, followed by direct farm and export sales ($714.8 million combined) and mass-market outlets ($210 million).
Fresh organic produce represented approximately 25% of organic sales in natural product retailers, bringing in $402 million in sales, up 21% from 1994. Other important organic products included bulk foods, frozen foods, drinks and dairy products. Organic clothing accounted for $2.5 million in sales. Statistics for direct farm and export sales ($714.8 million combined) are estimated because they are not tracked by USDA. USDA estimates total organic cropland at approximately 1,127,000 acres in 1996, up from an estimated 550,267 acres in 1991. The number of organic farmers almost doubled between 1991 and 1994, increasing from 2,841 to 4,060. )Natural Foods Merchandiser, June 1996)
Opposing camps are lobbying Congress both ways, to extend the deadline for methyl bromide phase-out and to accelerate the phase-out. In the meantime, science looks for answers. A combination of temperature, oxygen, nitrogen, and carbon dioxide may be an effective quarantine treatment. Quarantine treatments must be 99.9968% effective. Telone C-17 is reported to be as effective as methyl bromide for fumigating soil subsequently planted to bell pepper. Steam, electric heating, and methyl iodide are being tested for floriculture, with mixed results. In California, research shows that incorporating broccoli (yes, broccoli) into the soil will reduce Verticillium wilt in cauliflower. They have not identified the protective mechanism. Germany is experimenting with various options for fumigation, including parasitic wasps, heat, cold, controlled atmospheres, carbonyl sulfide, sulfuryl fluoride, and pheromones. Almost everyone agrees that the results are promising thus far, but the search for the best replacement for methyl bromide is not over. If you want to be added to the methyl bromide mailing list, call 301-344-2963.
Georgia growers can use Confirm (tebufenozide) to control beet armyworm on pepper until the end of the season. Dave Adams, vegetable entomologist, suggests using Confirm sparingly and after fruiting, if possible.
A Special Local Need registration has been issued for using Bueno 6 (MSMA) to control nutsedge in non-bearing pecans.
Mix your pesticides and other ingredients in the proper order, and pay attention to pH and water hardness. This item is not exactly new, but it is useful. If you don't mix various pesticides and adjuvants in the right sequence, it can affect pesticide performance. Unless the label directs otherwise (READ THE LABEL), add your ingredients to the water in the spray tank in the following order. 1) wettable powder, 2) flowables, 3), water solubles, 4) surfactants, and emulsifiable concentrates. Otherwise, liquid concentrates may coat wettable powders, forming a gunk that will not mix. Keep the agitation going the entire time. Do not allow the mix to stand overnight.
The pH affects how quickly many pesticides break down, and a small change in pH can have a large effect. For example, Imidan (phosmet) will last for 13 days at pH 4.5 and 14 hours at pH 7.0 but only 4 hrs at pH 8.0.
So, what do you do? Check the pH and hardness of your water. pH can vary substantially with the source of water, time of year, and time of day. Read the pesticide labels and talk to your pesticide dealer and county agent. They should have additional information about your specific situation. Finally, test new combinations of pesticides in small containers before you mix an entire tank. Someone once called me after they had mixed up a large tank full of two pesticides; they wanted to know if the pesticide were compatible. My reply was simply, "I hope so".
Are you batty? There is some evidence that bats may be useful pest control agents for agricultural systems. After all, bats eat a lot of moths, a group that includes many important pests. Some moths can also detect bats and may be chased away from fields. However, bats eat indiscriminately, so they may be eating beneficials as well. Building bat houses around a cotton field is probably a bit premature, but it might be worth a try around your garden.
M.L. Bell of N.C. State tested 27 greenhouse screening materials to exclude thrips and/or silverleaf whitefly. Only 3 of the screens tested excluded thrips; about excluded whitefly. Bugbed 123® and No-Thrips® excluded both.
B. Murphy and M.P. Parrella (UC Davis) report that releasing 12,000 predatory mites and 500 minute pirate bugs every other week in a 12,000 ft2 greenhouse did not control heavy populations of Western flower thrips. However, D.L. Olsen (U.Ga.) reported that WP formulations of Beuvaria bassiana were compatible with an aphid parasitoid. These findings could have be important for greenhouse IPM
Look for transfluthrin, a new pyrethroid. It is not registered here yet, but it is being used in Europe. It is reported to be up to 200 times more effective than other pyrethroids against public health and material pests. And it is supposed to be five times safer for mammals. No reports yet on agricultural possibilities.
USDA-ARS scientists report that red mulches may increase yields of tomato and other crops. Apparently, the light reflected by red mulch make the plants 'think' they are crowded, shifting resources into above-ground parts (including fruit). USDA and Sonoc Products, Inc. are testing the colored mulches with tomato, strawberry, pepper, and others. (ARS/USDA July 1996)
TeeJet is marketing new electronic pesticide delivery controls that can reduce spray volumes up to 80%. Other innovations include a selection of several droplet sizes, display of application rate/sprayer speed/area covered/volume remaining/pressure/etc. They are reported to be easy to use and designed for incorporation into a GPS system. Before you run to the store, however, count your money. It will cost you about $5000 to get what you need. Start considering these things. They are coming, and the prices will drop. My first calculator for school cost me about $75. My friends first digital watch cost him about $65. Now, you can buy a digital watch with a calculator for about $10.
What is the favorite way to get rid of yellow jackets (not the best, the favorite)?
I bet fire is near the top. A Greenville, S.C. man recently tried that method. He burned up most of his house and two cars. And people complain that pesticides are too dangerous. P.S. Pesticides work very well against yellow jackets.
It is very unlikely that any state will be able to get a waiver from state management plans. These plans have been mandated for states that use alachlor, metolachlor, or any of the triazines. That should include just about everybody. States that can demonstrate minimal groundwater contamination from these pesticides will be allowed to submit a 'minimal' plan (Pesticide and Toxic Chemical News 9-11-96)
Populations of lygus bugs in Arizona have been discovered to be resistant to aldicarb, dimethoate, imidacloprid, malathion, methomyl, and oxamyl. Resistance is believed to be related to the heavy use of these chemicals to control whitefly. (Resistant Pest Management, Summer '96)
A study from VPI has identified widespread German cockroach resistance to chlorpyrifos (Dursban), allethrin, fenvalerate, cyfluthrin, and cypermethrin.
From The Label (Purdue), 7% of agricultural retailers reported a pesticide spill in the last two years. The average bill for clean-up was nearly $7,000. A driver in the Midwest noticed a mini-bulk leaking but continued down the highway. Guess who they asked to pay for cleaning up miles of highway? Training is worth the investment.
New York has a new law requiring 100% reporting of pesticide manufacturing, sales and, usage. The new regulations are part of an investigation of breast cancer. California is the only state that currently has a similar law. They are considering revising their regulations, but some groups are encouraging them not keep the reporting requirements as they are. This type of reporting does provide important data, but it is very expensive to the pesticide industry and to the state.
APHIS has declared five more genetically engineered organisms safe for field testing. 1) corn engineered for resistance to some diseases, 2) a tobacco mosaic virus with pharmaceutical genes, 3) wheat stripe fungus with a genetic marker, 4) soybean tolerant to glufosinate, and 5) sweet potato tolerant to glufosinate.
Call APHIS at 301-734-3612 for more information.
EPA approved genetically engineered corn with a Bt gene to control European corn borer. It will available from Northrup King.
New regulations for Lannate (methomyl) are intended to protect workers
(I know what you are thinking. Just what is WPS supposed to do?). EPA and DuPont have agreed to:
1) reduce rates and number of applications
2) increase precautions to prevent exposure
3) increase the REI
4) delete some uses [Greenhouse uses are reported to be out. No report on other deletions.]
The National Cooperative Inner City Asthma Study was done to determine why asthma is such a big problem for children in low-income, inner city homes. The leading cause of asthma, by far, was the proteins in roach droppings and bodies. Should you be worried? Not if you control your roaches. A USDA study found that the median number of roaches in low-income apartments was 13,000. It makes my skin crawl to think of it. This discovery is good news, however. Now that the cause of the asthma is identified; it can be controlled.
According to the Environmental Sensitivities Research Institute, Multiple Chemical Sensitivity will now be referred to as Idiopathic Environmental Intolerances. I do like to make jokes, but I will not touch this one.
Twenty two farm workers
including three pregnant women were rushed to
hospitals last week after being poisoned
hospitals last week after being poisonedby a mixture of Lorsban(chlorpyrifos), Danitol (fenpropathrin) and Curacron (profenofos) while harvesting grapes. The mixture was being applied by air to a nearby cotton field. The crop dusting company maintained that the pilot was experienced and followed all regulations.
The county reported that poisoning was "a somewhat
unique occurrence," and that "for a crop duster plane to affect a mass of
people, that's not common at all." United Farm Workers thought differently, charging that "thousands of farm workers in vineyards and fields are exposed to toxic poisons every day -- often without their knowledge."
