When viewing the chart, please keep the follow in mind: The under-­ lying cause of most bee poisoning incidents is a lack of awareness, rather than … However, some of the risk to pollinators is limited by their slight repellent activity and rapid breakdown. Acute toxicity tests on adult honey bees may be particularly ill-suited for the testing of systemic pesticides because of the frequency of exposure bees are likely to ex­perience in field applications. If mixed with DMI fungicides FRAC code 3 (e.g., propiconazole, tebuconazole, triflumizole), or SDHI and QoI fungicides FRAC codes 7 and 11 (boscalid and pyraclostrobin, Pristine), or chlorothalonil fungicide FRAC code M05, may increase toxicity to bees. Pyrethrins are highly to very highly toxic to fish. For example, the codes for PYRIDABEN/SULFUR (Desperado) are "21A/UN" as an acaricide (IRAC codes), "—/M02" as a fungicide (FRAC codes), and "21A/UN" as an insecticide (IRAC codes). If mixed with insecticides, increases hazard to bees. If mixed with diamide insecticides IRAC group 28 (e.g., chlorantraniliprole, cyantraniliprole, flubendiamide), may increase toxicity to bees. In such cases, acute toxicity data may still be warranted but chronic toxicity data may be of limited value in the risk assessment. The Bee Toxicity Table provides an overview of the lethal dose for each insecticide which results in 50% mortality to honey bees in the test population (also known as the LD50). Many bee-toxic pesticides can be used on blooming crops in an appropriate “window” of time. Honey Bee (Apis mellifera) Toxicity of Residues on Foliage study (OCSPP Guideline 850.3030 A keen awareness of the level of Varroa mites in the hive is a primary concern for most beekeepers.

How to Reduce Bee Poisoning from Pesticides - 2013. Acute toxicity is determined by examining the dermal toxicity, inhalation toxicity, and oral toxicity of test animals. If mixed with dicarboximide fungicides FRAC code 2 (e.g., iprodione, vinclozolin), or organophosphate insecticides IRAC group 1B (e.g., acephate, chlorpyrifos, malathion), or neonicotinoid insecticides IRAC group 4A (e.g., acetamiprid, clothianidin, imidacloprid, thiamethoxam, thiacloprid), may increase toxicity to bees. Acute toxicity is measured as the amount or concentration of a toxicant-- the a.i.--required to kill 50 percent of the animals in a test population. It is important to be able to identify healthy brood stages. If mixed with spinosyns IRAC group 5 (spinetoram, spinosad), may increase toxicity to bees. Does Pyrethrum Kill Bees?. of Agriculture and CS, Structural Pest Control and Pesticides Division from the: NC Agricultural Chemicals Manual (2016); highly toxic to honey bees on an acute basis (LD50>0.0439 mg/bee). They are also very highly toxic to lobster, shrimp, oysters, and aquatic insects. The chart includes each chemical’s LD50 value (toxicity measurement), and signal words, ranging from “CAUTION” on slightly toxic insecticides, to “WARNING” on moderately toxic pesticide and “DANGER” on those that are highly toxic. 2013 ). Bees can suffer serious effects from toxic chemicals in their environments. Pyrethrins are practically non-toxic to birds but highly toxic to honey bees. Employ Residual Toxicity Safeguards. Red = Highly Toxic to Bees (LD50<2µg a.i./bee); Yellow = Moderately Toxic to Bees (LD50 2-11 µg a.i./bee); Green = Relatively Non-toxic to Bees (LD50>11µg a.i./bee) The information in this table was compiled by the NC Dept. Pollinators are essential for obtaining high yields in most cultivated crops. 2.
