If mixed with insecticides, including pyrethroids IRAC group 3A (e.g., cyhalothrin, cypermethrin, tau-fluvalinate), or neonicotinoids IRAC group 4A (e.g., acetamiprid, clothianidin, imidacloprid, thiamethoxam, thiacloprid), or butenolide IRAC group 4D (flupyradifurone), or chitin biosynthesis inhibitors IRAC group 15 (e.g., diflubenzuron, novaluron), or diamides IRAC group 28 (chlorantraniliprole, cyantraniliprole, flubendiamide), may increase toxicity to bees. 2 Compiling the Colorado Bee List The Colorado Bee List (page 23) documents 946 valid living (modern) bee species in 66 genera recorded from the state. If mixed with thiophanate fungicides FRAC code 1 (e.g., thiophanate-methyl), or DMI fungicides FRAC code 3 (e.g., propiconazole, tebuconazole, triflumizole), or copper fungicides FRAC code M01 (e.g., Bordeaux mixture, copper hydroxide), or chlorothalonil fungicide FRAC code M05, may increase toxicity to bees. Pacific Northwest Extension publication PNW591 . A total of 141 subspecies … 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). Be familiar with how toxicity is measured and what is meant by label warning statements. Employ Residual Toxicity Safeguards. Residual 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 smaller the LD 50, the more toxic the product. 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. If mixed with DMI fungicides FRAC code 3 (e.g., propiconazole, tebuconazole, triflumizole), or anilinopyrimidine fungicides FRAC code 9 (e.g., cyprodinil, pyrimethanil), may increase toxicity to bees. If mixed with dicarboximide fungicides FRAC code 2 (e.g., iprodione, vinclozolin), or insecticides, including pyrethroids IRAC group 3A (e.g., cyhalothrin, cypermethrin, tau-fluvalinate), or neonicotinoids IRAC group 4A (e.g., acetamiprid, clothianidin, imidacloprid, thiamethoxam, thiacloprid), or butenolide IRAC group 4D (flupyradifurone), or chitin biosynthesis inhibitors IRAC group 15 (e.g., diflubenzuron, novaluron), may increase toxicity to bees. Reference to trade names does not imply endorsement by the MDA; list is based on products sold in Minnesota and does not include all product names or information. Although these precautions are based on toxicity to honey bees, they are also relevant to other species of bees, with some exceptions as noted in Table 4. Understand what toxicity is and how it affects humans. Their use, however, comes with the responsibility to follow the label and select a product that will best control the target pest, while minimizing harm to humans and the environment. Best to avoid: Amaryllis. For beekeepers and farmers who provide and receive pollination, it is critical to know which pesticides are known to be toxic to bees, as well as their bee related warning statements in order to avoid honey bee poisoning events. 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. (c) Honey bee acute oral toxicity test protocol available through OECD TG 213. Beautiful and simple to grow, dahlias often flower until the first frosts of the year. If mixed with DMI fungicides FRAC code 3 (e.g., propiconazole, tebuconazole, triflumizole), may increase toxicity to bees. 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. Insecticide applications are an important management tool in controlling pest populations. Beekeeper Notification. Evening applications are generally the least harmful to honey bees, but stricter application restrictions may be necessary when a pesticide has extended residual toxicity (ERT). 2. It has the potential for toxic chronic exposure to honey bees, as well as other non-target pollinators through the translocation of clothianidin resides in nectar and pollen. Pesticides toxic to honey bees. "Pesticide" is a general term used for a chemical designed to kill target pests such as insects … If mixed with neonicotinoid insecticides IRAC group 4A (e.g., acetamiprid, clothianidin, imidacloprid, thiamethoxam, thiacloprid), may increase toxicity to bees. Dahlias are a highlight of late summer gardens. 3.". Many of the action steps which resulted from this review aim towards protecting pollinators. If mixed with diamide insecticides IRAC group 28 (e.g., chlorantraniliprole, cyantraniliprole, flubendiamide), may increase toxicity to bees. Chronic feed­ing tests using whole colonies may provide a … However, in recent years, the bee population has decreased throughout the world ( Lebuhn et al. When viewing the chart, please keep the follow in mind: If mixed with thiophanate fungicides FRAC code 1 (e.g., thiophanate-methyl), or pyrethroid insecticides IRAC group 3A (e.g., cyhalothrin, cypermethrin, tau-fluvalinate), or neonicotinoid insecticides IRAC group 4A (e.g., acetamiprid, clothianidin, imidacloprid, thiamethoxam, thiacloprid), may increase toxicity to bees. Mode-of-action codes are presented in the order of the common names to which they apply in the row (line) naming their type. Period of residual toxicity to honey bees after application. bees in a broader context by summarizing some of their important life history traits. In honey bees, the affects of this toxic chronic Wood Toxicity and Allergen Chart. 625 Robert Street North Herbicides primarily harm bees indirectly, by reducing the availability of flowering plants that produce nectar, pollen, and bee nesting material. Exotic and interesting, heliconia, or lobster-claws as its sometimes called, is very toxic to bees. contact toxicity (µg/bee) to obtain a number of lethal doses per area regardless of foliage density or other complicating variables (EPPO 2010). If mixed with thiophanate fungicides FRAC code 1 (e.g., thiophanate-methyl), or insecticides, including pyrethroids IRAC group 3A (e.g., cyhalothrin, cypermethrin, tau-fluvalinate), or neonicotinoids IRAC group 4A (e.g., acetamiprid, clothianidin, imidacloprid, thiamethoxam, thiacloprid), or butenolide IRAC group 4D (flupyradifurone), or chitin biosynthesis inhibitors IRAC group 15 (e.g., diflubenzuron, novaluron), or diamides IRAC group 28 (chlorantraniliprole, cyantraniliprole, flubendiamide), may increase toxicity to bees.
