Insecticide Update: Endosulfan (Thionex)

Friday, June 25th, 2010

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

This news release was received as an EPA Pesticide Program Update from EPA’s Office of Pesticide Programs on June 10, 2010.

“EPA Moves to Terminate All Uses of Insecticide Endosulfan to Protect Health of Farmworkers and Wildlife

“The U.S. Environmental Protection Agency (EPA) is taking action to end all uses of the insecticide endosulfan in the United States. Endosulfan, which is used on vegetables, fruits, and cotton, can pose unacceptable neurological and reproductive risks to farmworkers and wildlife and can persist in the environment.

“New data generated in response to the agency’s 2002 decision have shown that risks faced by workers are greater than previously known. EPA also finds that there are risks above the agency’s level of concern to aquatic and terrestrial wildlife, as well as to birds and mammals that consume aquatic prey which have ingested endosulfan. Farmworkers can be exposed to endosulfan through inhalation and contact with the skin. Endosulfan is used on a very small percentage of the U.S. food supply and does not present a risk to human health from dietary exposure.

“Makhteshim Agan of North America, the manufacturer of endosulfan, is in discussions with EPA to voluntarily terminate all endosulfan uses. EPA is currently working out the details of the decision that will eliminate all endosulfan uses, while incorporating consideration of the needs for growers to timely move to lower-risk pest control practices.

“Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA must consider endosulfan’s risks and benefits. While EPA implemented various restrictions in a 2002 re-registration decision, EPA’s phaseout is based on new data and scientific peer review, which have improved EPA’s assessment of the ecological and worker risks from endosulfan. EPA’s 2010 revised ecological risk assessment reflects a comprehensive review of all available exposure and ecological effects information for endosulfan, including independent external peer-reviewed recommendations made by the endosulfan Scientific Advisory Panel.

“Endosulfan, an organochlorine insecticide first registered in the 1950s, also is used on ornamental shrubs, trees, and herbaceous plants. It has no residential uses.”

Thursday, April 22nd, 2010

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

Belay (clothianidin) – A supplemental label was recently approved by EPA. Crops included on the supplemental label include number of vegetable crops (brassicas, cucurbits, fruiting vegetables, and leafy vegetables) as well as peaches. In addition to the label on the pesticide container, you must also have a copy of the supplemental label in your possession to use Belay on these new crop additions (http://www.cdms.net/LDat/ld8J6008.pdf).

Insecticide Updates

Thursday, March 4th, 2010

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

The following are a few new insecticide registrations as well as changes with labeled products that occurred since the last newsletter of 2009. As always, be sure to check the label for labeled crops, labeled crops within a crop grouping, use rates and restrictions. Federal labels can be found at http://www.cdms.net/. In addition, you should also check the Delaware Department of Agriculture’s website to be sure these materials are labeled in Delaware http://www.kellysolutions.com/de/pesticideindex.htm (to use a material it must have both a state and federal label).

Baythroid XL (beta cyfluthrin) – A new supplemental label now exits and the following revisions and additions to the label include: revised buffer zone requirements, revised spray drift requirements, revised maximum usage chart , increased use rate on alfalfa, new use on cereal grain, and additional pests on grass http://agdev.anr.udel.edu/weeklycropupdate/wp-content/uploads/2010/03/Baythroid.pdf

Belay (clothianidin) – This label recently expanded to include control of sucking and chewing insects infesting cotton, cranberry, fig, grape, pome fruit, pomegranate, soybean, tuberous and corm vegetables (includes sweet potatoes) and tree nuts (http://www.cdms.net/LDat/ld8J6006.pdf). More vegetable registrations are expected this spring – we will let you know when registrations are received.

Coragen (chlorantraniliprole) – A label expansion occurred at the end of January 2010. Crops that have been added that are important to Delaware include corn (field and sweet), grass (forage, fodder and hay), a number of crops in the herb subgroup, snap beans, lima beans, field and garden peas, non-grass animal feeds, tuberous and corm vegetables. Please refer to the following link for use rates and the full list of crops included (http://www.cdms.net/LDat/ld8KF022.pdf).

Furadan (applies to all crops): “Effective December 31, 2009, all crop tolerances for carbofuran were revoked by the United States Environmental Protection Agency. This action by EPA effectively stops the use of Furadan on all food crops. As a result of the revocation, the Delaware Department of Agriculture has also cancelled all Special Local Needs labels for all Furadan products labeled in Delaware. Contact your pesticide distributor for assistance with the return or disposal of the any existing stocks. The Department understands that unopened containers may be returned to the pesticide distributors and that open container should be disposed of at local pesticide disposal days. FMC is accepting inventory as follows:

● Full and partially full 15 & 110 gallon U-Turns®

● Unopened 2×2.5 gallon cases in original FMC packaging

Delaware farmers are permitted to dispose of pesticides during Delaware Solid Waste Authority Household Hazardous Waste collection days. DSWA has requested that you contact the DSWA’s Citizen Response Line at 1-800-404-7080 prior to delivery of the pesticides for disposal to make sure DSWA can handle the quantity being disposed of. FMC can be contacted for specific instruction for product return at 1-800-231-5808.” Information provided by Dave Pyne at Delaware Department of Agriculture (302-698-4500).

Inovate – Soybean Seed Treatment – This new soybean seed treatment is now labeled and approved for use in Delaware. It includes the insecticide, NipsIt (clothianidin) and Rancona Xxtra (ipconazole and metalaxyl).

Regent: The following correspondence regarding the use of Regent was received from BASF (the manufacturer of Regent) in February 2010: “On February 3, 2010, the EPA posted a Federal Register notice advising of its decision to allow the expiration of conditional registrations of select fipronil-based products, specifically REGENT 4SC for in-furrow corn application. The EPA felt a number of viable alternatives exist for treating corn furrows for root worm control. Specifically,
(a) REGENT 4SC remains registered for use in potatoes. However, the conditional registration for the commercial product for in-furrow corn application has been allowed to expire effective November 15, 2009.
(b) BASF may manufacture REGENT 4SC with the label bearing both corn in-furrow and potato until March 31, 2010, and after which time it will be labeled for use on potatoes only in the U.S. marketplace (except NY where it never had a potato use).
(c) BASF may sell REGENT 4SC for corn in-furrow use through May 15, 2011. Distributors and retailers can sell, and growers can use, REGENT 4SC for corn in-furrow applications until stocks are depleted.

(d) Additionally, the EPA changed registrations on REGENT TS and REGENT 500TS for corn seed treatment, to grant unconditional registration for treatment of seeds for export only. No sales of fipronil treated seeds will be allowed within the U.S. without an EPA-approved product stewardship plan. BASF will work with seed partners to develop a stewardship plan that will be deemed mutually acceptable by both BASF and the EPA to allow fipronil-based solutions for the future protection of premium seeds in the U.S.”

New Vegetable Insecticides/New Uses

Friday, April 10th, 2009

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

Vetica (Nichino) – This newly registered material is a combination of flubendiamide and buprofezin. It is labeled on a number of crop groups including leafy vegetables (except brassicas), fruiting vegetables, and cucurbits. The label lists control of a number of “worm” species as well as suppression of leafhoppers and whiteflies. Please see the label for use rates and restrictions http://www.cdms.net/LDat/ld8TA000.pdf.

Coragen (DuPont) – Potatoes were recently added to the full section 3 (federal) Coragen label. A number of new soil applied uses (in addition to drip chemigation) were also added for brassicas, cucurbits, fruiting and leafy vegetables. These uses include in-furrow sprays, transplant water or hill drench, surface banding and soil shank injection. Refer to the label for use rates, application directions and restrictions http://www.cdms.net/LDat/ld8KF013.pdf.

Vegetable Crop Insects

Friday, August 15th, 2008

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

New Insecticide Registrations
Bayer Crop Science recently received federal and state registrations for their new active ingredient flubendamide. It is the active ingredient in Belt and Synapse. Belt is labeled for sweet corn. Synapse is labeled for a number of vegetables. See labels for use rates and restrictions. They have not been posted to CDMS yet. Bayer also received registration for another new active ingredient spirotetramt which will be sold under the trade name, Movento. It is labeled for aphid and whitefly control on a number of vegetable crops. Please see labels for use rates, restrictions and labeled crops (http://www.cdms.net/LDat/ld8L5005.pdf).

Cabbage
Continue to sample for cabbage looper, diamondback larvae and harlequin bug. Although the pyrethroids will provide control of harlequin bugs they are not effective on diamondback in our area. So be sure to scout and select control options based on the complex of insects present in the field.

Cucumbers
Be sure to watch for an increase in cucumber beetle and aphid populations. Fresh market cucumbers are susceptible to bacterial wilt, so treatments should be applied before beetles feed extensively on cotyledons and first true leaves. Although pickling cucumbers have a tolerance to wilt, a treatment may still be needed for machine-harvested pickling cucumbers when 5% of plants are infested with beetles and/or plants are showing fresh feeding injury. A treatment should be applied for aphids if 10 to 20 percent of the plants are infested with aphids with 5 or more aphids per leaf.

Lima Beans
Continue to scout for spider mites, stink bugs and lygus bugs. Be sure to sample for corn earworm larvae as soon as pin pods are present. A treatment will be needed if you find one corn earworm larvae per 6 ft-of-row.

Melons
Continue to scout all melons for aphids, cucumber beetles, and spider mites. We continue to see an increase in aphid populations. Treatments should be applied before populations explode and leaf curling occurs.

Peppers
In areas where corn borers are being caught in local traps, fields should be sprayed on a 7-day schedule for corn borer control. As soon as corn borer trap catches increase to above 10 per night, a 5 to 7-day schedule may be needed. Since trap catches can increase quickly at this time of year, be sure to check local moth catches in your area by calling the Crop Pest Hotline (in state: 1-800-345-7544; out of state: 302-831-8851) or visiting our website at (http://ag.udel.edu/extension/IPM/traps/latestblt.html). We continue to find beet armyworms (BAW) so be sure to watch for feeding signs and apply treatments before significant webbing occurs. You will also need to consider a treatment for pepper maggot. We continue to find aphids in fields and populations can explode quickly, especially where beneficial insect activity is low. As a general guideline, treatment may be needed if you find one or more aphids per leaf and beneficial activity is low.

Snap Beans
At this time of year, you will need to consider a treatment for both corn borer and corn earworms. Sprays are needed at the bud and pin stages on processing beans for corn borer control. An earworm spray may also be needed at the pin stage. Just as a reminder, Orthene (acephate) will not provide effective corn earworm control in processing snap beans. If Orthene is used for corn borer control you will need to combine it with a corn earworm material (e.g. a pyrethroid). You will need to check our website for the most recent trap catches to help decide on the spray interval between the pin stage and harvest for processing snap beans (http://ag.udel.edu/extension/IPM/traps/latestblt.html and http://ag.udel.edu/extension/IPM/thresh/snapbeanecbthresh.html). Once pins are present on fresh market snap beans, a 7 to 10-day schedule should be maintained for corn borer and corn earworm control.

Spinach
As the earliest planted spinach emerges from the ground, be sure to watch for webworms and beet armyworms. Controls should be applied when worms are small and before they have moved deep into the hearts of the plants. Also, remember that both insects can produce webbing on the plants.

Sweet Corn
The first silk sprays will be needed as soon as ear shanks are visible. Be sure to check both blacklight and pheromone trap catches for silk spray schedules since the spray schedules can quickly change. Trap catches are generally updated on Tuesday and Friday mornings (http://ag.udel.edu/extension/IPM/traps/latestblt.html and

http://ag.udel.edu/extension/IPM/thresh/silkspraythresh.html). You can also call the Crop Pest Hotline (in state: 1-800-345-7544; out of state: 302-831-8851). A whorl stage treatment should be considered for fall armyworm when 12-15% of the plants are infested. Since fall armyworm feed deep in the whorls, sprays should be directed into the whorls and multiple applications are often needed to achieve control. At this time of year you will need to combine a fall armyworm material with a pyrethroid for the first 2-3 silk sprays for fall armyworm control. Be sure to check all labels for days to harvest and maximum amount allowed per acre.

Cancellation of Carbofuran (Furadan)

Friday, July 25th, 2008

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

We just received this notice from EPA on Furadan.

“Due to considerable risks associated with the pesticide carbofuran in food and drinking water, EPA is revoking the regulations that allow carbofuran residues in food. Even though carbofuran is used on a small percentage of the U.S. food supply and therefore the likelihood of exposure through food is low, EPA has identified risks that that do not meet our rigorous food safety standards. EPA is taking the necessary steps to address these risks to ensure we have the safest food supply possible. The United States has a safe and abundant food supply, and children and others should continue to eat a variety of foods, as recommended by the federal government and nutritional experts.

“In addition, EPA is proceeding on the path toward cancellation of the pesticide registration, which will address the risks to pesticide applicators and birds in treated fields. As part of this effort, EPA is also releasing its response to the peer review conducted by the independent Scientific Advisory Panel and the agency’s response to the U.S. Department of Agriculture’s comments on the effect of the cancellation of carbofuran on the agricultural economy.

“EPA will accept public comments on the proposed tolerance revocation for 60 days. For additional information, visit: http://www.epa.gov/pesticides/reregistration/carbofuran/carbofuran_noic.htm.”

Insecticide Combinations

Thursday, June 26th, 2008

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

In recent years, there have been a number of new insecticides introduced to the marketplace that combine 2 active ingredients. As we enter the time for spraying multiple pests on various crops, the following is a list of some of the products that I am aware of. Some products are labeled on a narrow range of crops and others on a more expanded list. This is by no means a complete list, but just some of the materials that we have received notice about from the manufactures. We also have little or no experience with these products but will be testing a few in our 2008 trials. You will need to refer to the labels for labeled crops, use rates and restrictions.

● Brigadier (FMC) – combination of bifenthrin and imidacloprid. (http://www.cdms.net/LDat/ld8LA000.pdf)

● Cobalt (Dow) – combination of chlorpyrifos and gamma-cyhalothrin (http://www.cdms.net/LDat/ld8AA000.pdf)
