Dr. ![]() If a pesticide must be used, apply spot treatments of contact insecticides instead.Ģ021 Japanese Beetle Management, Dr. Flowering plants that open after systemic insecticides are sprayed can contain the insecticide residue for many months or more in the leaves, pollen and nectar. Avoid using systemic insecticides on flowering plants that pollinators visit. Neonicotinoid application methods include seed treatments, foliar sprays, soil and trunk drenches, and trunk-injections. However, in spite of high toxicity to pollinators, neonicotinoids are the most widely-used insecticides in the world due to their low mammalian toxicity and the ability of the insecticide to move systemically from soil into the entire plant. They have lethal and sublethal effects on insect species by affecting the central nervous system which results in paralysis and death. Neonicotinoids are a class of systemic insecticide particularly harmful to bees and other pollinators. For these and numerous other reasons, insecticides are not safe to use around pollinators and other beneficial insects.Ī systemic insecticide is absorbed into the plant's vascular system, leaving the entire plant toxic to both target and non-target insect species. Numerous papers have shown that lower, sublethal amounts of insecticides affect behavior and alter the ability of insects to find food and survive. Recent papers demonstrate that some inert ingredients are also highly toxic to bees, and also fungicides demonstrated toxicity to bees. Insecticides are designed to destroy both target and non-target insects. Inert ingredients are penetrating agents, odor maskers, stabilizers, preservatives, diluents, surfactants, emulsifiers, propellants, solvents, spreaders, stickers, antifoaming agents, dyes, and drift retardants that modify the physicochemical properties of the spray mixture. The active ingredient is the chemical registered by the EPA as toxic to pest and beneficial insects. Pesticide active and inert ingredients can be found on the label of the pesticide container. Pesticides include herbicides, fungicides and insecticides. Potato crop sprayed with systemic insecticide.
