• The Section 18 exemption for CheckMite+ (coumaphos) has been extended February 1, 2004. Information on this and other Section 18s can be found on the Table of Active Section 18 Exemptions for Arizona page.
• "ORGANIC STANDARDS EFFECTIVE OCTOBER 21. The USDA has put in place a set of national standards that food labeled as "organic" must meet, whether it is grown in the United States or imported from other countries. When buying
  food labeled as "organic", it was produced using the highest organic
  production and handling standards in the world. Organic food is produced
  by farmers who emphasize the use of renewable resources and the
  conservation of soil and water to enhance environmental quality for future
  generations. Organic meat, poultry, eggs, and dairy products come from
  animals that are given no antibiotics or growth hormones. Organic food is
  produced without using most conventional pesticides; petroleum-based
  fertilizers or sewage sludge-based fertilizers; bio-engineering; or
  ionizing radiation. Before a product can be labeled "organic", a
  government-approved certifier inspects the farm where the food is grown to
  make sure the farmer is following all the rules necessary to meet USDA
  organic standards. Companies that handle or process organic food must be
  certified, too. Consumers must look at package labels and watch for signs
  in the supermarket. Along with the national organic standards, USDA
  developed strict labeling rules to help consumers know the exact organic
  content of the food they buy. The USDA Organic seal identifies that a
  product is at least 95 percent organic. Excerpted from the USDA National
  Organic Program website, http://www.ams.usda.gov/nop/ , where further
  details and lists of certifiers are available. In Arizona, the Dept. of
  Agriculture will not be an accredited certifier while it has adopted a
  neutral position regarding certification of producers and handlers and any
  enforcement issues." - October 11, 2002 Vegetables Newsletter
• "Intrepid 2F (methoxyfenozide; Dow AgroSciences - label) insecticide was granted a label in Arizona last week (October 7-11, 2002) and is now available for local use in leafy vegetables and cole crops. The product is an IGR (molt accelerating compound) with good residual activity at on cabbage looper and beet armyworm at appropriate rates. A "New" EPA Label for Avaunt WG (indoxacarb; DuPont - label) insecticide with a higher use rate range of 3.5 to 6.0 oz/ac (0.065 to 0.11 lbai/ac) for lettuce (head and leaf varieties) has been approved. The compound is effective against beet armyworm and cabbage looper as well. Both products are considered reduced-risk insecticides and have excellent fits in our Lettuce and Cole Crop IPM programs." - October 15, 2002 Desert Vegetable Advisory

• Pesticide Information Center Changes - The National Pesticide Information Center (NPIC) is the new name for a U.S.-based cooperative service that provides objective, science-based information for pesticide products, recognition and management of pesticide poisoning, toxicology, and environmental chemistry. NPIC, formerly known as the national pesticide telecommunication network, is staffed by specialists and offers toll-free phone service at 1-800-858-7378 (in the U.S.) from 6:30am-4:30pm Pacific time seven days per week (excluding holidays). For those with internet access, the Center's website is http://NPIC.orst.edu/brochure.htm where several publications in both electronic (free) and paper form (to order) are available.
• Crop Rotation Limitations - Herbicide labels frequently list the crops and the time intervals when they can be replanted into ground previously treated. The interval ensures the safe production of the next crop or safeguards the next crop of any residues if a tolerance has not been established. Many new products such as Sandea for weed control in melons currently list many vegetable crops that have to wait several months before replanting. Currently, lettuce, onions, and most cole crops must wait 18 months to plant after applications on a previous melon crop. Field studies have indicated that lettuce and broccoli were not affected at as short as 4 to 5 months and also when replanted a second time at 15 to 16 months. The fate of the herbicide is subject to many factors including tillage operations to mix the soil, soil characteristics, irrigations, sunlight, microbial activity, method of application, and timing of treating the crop (foliar or soil). The conservative limitations will be re-evaluated when sufficient data and experience assure that sensitive crops demonstrate good tolerance to newly introduced herbicides. In the meantime, labels must be strictly adhered to until followcrops can be grown with reasonable certain safety.

• EPA Proposed Revocation of Tolerances
  
  Federal Register: April 15, 2002
  http://www.epa.gov/fedrgstr/EPA-PEST/2002/April/Day-15/p9070.htm
  Volume 67, Number 72
  Proposed Rules Page 18150-18160
  
  SUMMARY: This document proposes to revoke certain tolerances for residues of the pesticides acephate, amitraz, carbaryl, chlorpyrifos, cryolite, disulfoton, ethalfluralin, ethion, ethoprop, fenthion, fluvalinate, methamidophos, metribuzin, oxamyl, phorate, phosalone, phosmet, pirimiphos-methyl, profenofos, propiconazole, tetrachlorvinphos, thiram, and tribufos because these specific tolerances are either no longer needed or are associated with food uses that are no longer current or registered in the United States. The regulatory actions proposed in this document are part of the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and the tolerance reassessment requirements of the Federal Food, Drug, and Cosmetic Act (FFDCA) section 408(q), as amended by the Food Quality Protection Act (FQPA) of 1996. By law, EPA is required by August 2002 to reassess 66% of the tolerances in existence on August 2, 1996, or about 6,400 tolerances. The regulatory actions in this document pertain to the proposed revocation of 153 tolerances.
  
  COMMENTS: Comments, identified by docket control number OPP-2002-0019, must be received on or before June 14, 2002. Comments may be submitted by mail, electronically, or in person.
  
  This proposed rule provides a comment period of 60 days for any person to state an interest in retaining a tolerance proposed for revocation. If EPA receives a comment within the 60-day period to that effect, EPA will not proceed to revoke the tolerance immediately. However, EPA will take steps to ensure the submission of any needed supporting data and will issue an order in the Federal Register under FFDCA section 408(f) if needed. The order would specify data needed and the time frames for its submission, and would require that within 90 days some person or persons notify EPA that they will submit the data. If the data are not submitted as required in the order, EPA will take appropriate action under FFDCA. EPA issues a final rule after considering comments that are submitted in response to this proposed rule. In addition to submitting comments in response to this proposal, you may also submit an objection at the time of the final rule. If you fail to file an objection to the final rule within the time period specified, you will have waived the right to raise any issues resolved in the final rule. After the specified time, issues resolved in the final rule cannot be raised again in any subsequent proceedings.

• OP Alternative Status Granted to the New Insecticide, Flonicamid (F 1785 GH), for Use on Ornamentals Grown in Indoor Greenhouses. Alternative to OP's and Other Chemistries.
  
  Here is a recent item from the Office of Pesticide Programs about a chemical in the registration process that has been given "reduced risk" status. This status usually streamlines the registration process for a chemical.
  
  On April 9, 2002 the OPP Reduced Risk Committee granted OP alternative status ISK Biosciences and FMC's insecticide, flonicamid (F 1785 GH), for use on ornamentals grown in indoor greenhouses. Flonicamid is an alternative to the OP's chlorpyrifos, acephate, dimethoate, and oxydementon methyl; the carbamate, enoxycarb; and the pyrethroids, bifenthin, and fluvalinate, for use on indoor greenhouse ornamentals to control sucking insects (e.g. aphids, trips, and whiteflies). Flonicamid is a systemic (plant) insecticide that immediately suppresses the feeding of sucking insects. It's mode of action, although unknown, appears to be unique and should help with pest resistance management. Flonicamid does not work on acetylcholine esterase (OP's and carbamates), or nicotinic acetylcholine receptors (neo-nicotinoids).
  
  Summary of Uses and Alternatives Mode of action: mode of action unknown but not active on acetylcholine esterase, or nicotinic acetylcholine receptors
  Site: indoor greenhouse ornamentals
  Pests: aphids, thrips, whiteflies, leafhoppers, mealybugs, scale, stinkbuts, plant bugs
  Alternative for:
  OP's chlorpyrifos, acephate, dimethoate, oxydementon methyl
  Carbamates: fenoxycarb
  Other: acetamiprid, thiamethoxam, imidacloprid, bifenthin, fluvalinate

• Guthion uses - Negotiations are under way between the Environmental Protection Agency and manufacturers to preserve some uses of the organophosphate pesticide azinphos-methyl (Guthion) that were originally considered unsuitable for reregistration. EPA said all 28 currently approved label uses of azinphos-methyl were ineligible for reregistration in order to decrease exposures and protect farmworkers. The agency said it identified conditions under which a limited number of uses of the pesticide could continue under a time-limited registration through October 2005. The agency also said it would require a phaseout of seven other uses that were of "high benefits," so growers could transition to other means of pest control. It is expected that use of azinphos-methyl on nectarines, plums, prunes, and potatoes would no longer be considered ineligible for reregistration The agency says azinphos-methyl and other organophosphates cannot be definitively reassessed until EPA examines their cumulative risk as a group of chemicals. The Guthion label now shows uses for cotton, melons, onions, citrus fruits, pecans, peaches, bushberries, grapes, strawberries, filberts, walnuts, broccoli, brusssels sprouts, cabbages, cauliflower, celery, cucumbers, eggplant, and tomatoes.
