Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals).
Imidacloprid is a systemic insecticide, belonging to the class of chloronicotinyl neonicotinoid insecticides. It works by interfering with the transmission of nerve impulses in insects by binding irreversibly to specific insect nicotinic acetylcholine receptors. [28] It is in IRAC group 4A.
Dimethoate is a widely used organophosphate insecticide and acaricide.It was patented and introduced in the 1950s by American Cyanamid.Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, an enzyme essential for central nervous system function.
Nitenpyram is highly selective towards the variation of the nACHr which insects possess, and has seen extensive use in targeted, insecticide applications. Known under the codename TI 304 during field testing starting in 1989, the compound's first documented commercial use was in 1995 under the name "Bestguard" as an agricultural insecticide. [1]
Neonicotinoids are water-soluble, so when the seed sprouts and grows, the developing plant absorbs the pesticide into its tissues as it takes in water. [9] Neonicotinoids can also be applied to the soil directly. [10] Once absorbed, neonicotinoids become present throughout the plant, including in its leaves, flowers, nectar, and pollen. [8]
Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole insecticide class. [3] Fipronil disrupts the insect central nervous system by blocking the ligand-gated ion channel of the GABA A receptor (IRAC group 2B) and glutamate-gated chloride (GluCl) channels. This causes hyperexcitation of contaminated insects' nerves and muscles.
Raid is the brand name of a line of insecticide products produced by S. C. Johnson & Son, first launched in 1956.. The initial active ingredient was allethrin, the first synthetic pyrethroid. [1]
Bifenthrin is poorly soluble in water and often remains in soil. Its residual half-life in soil is between 7 days and 8 months, depending on the soil type, with a low mobility in most soil types. Bifenthrin has the longest known residual time in soil of insecticides currently on the market. It is a white, waxy solid with a faint sweet smell.
