Some Reduced Risk Pesticides Used in Vegetables April 2007 (be sure to check and follow all label instructions) Trade Name Chemical Name Confirm, Intrepid tebufenozide, methoxyfenozide Spintor Spinosad Proclaim Avermectinsemamectin benzoate Fullfill How it works What it controls IGR – ecdysone agonist causes a premature lethal molt. Mostly through ingestion, some contact, feeding ceases in 24 hrs, death in 23 days Microbial metabolite-- fermentation product (interferes with nicotinelike receptors in nerve endings) of soil bacteria-Actinomycetes Microbial metabolite, Mostly through ingestion. Disruption of nerve impulses causes paralysis in hours, death in days Small Lepidopteran larvae (worms or caterpillars) such as armyworms, beet AW, tomato fruit worm, loopers, hornworm, yellow striped AW. Lepidoptera larvae, leaf miners, many thrips species, Colorado potato beetle Pymetrozine Stops aphids from feeding quickly after initial contact. Aphids may remain alive for days, but don’t feed. Translaminar and systemic Aphids, some activity on whiteflies Avaunt Indoxacarb Lepidoptera larvae, beet AW, diamond back moth, fruit worms Courier, Applaud Buprofezin Agri-Mek Avermectins Knack Pyriproxyfen – slow acting Inhibits Na+ entry into nerve cells, paralysis and death 6-48 hours. Contact and ingestion IGR – Chitin synthesis inhibitor, contact and ingestion Fermentation product of soil bacterium Steptomyces avermitilis, via ingestion. Inhibits signal transmission at neuromuscular junctions. Translaminar IGR- Juvenile hormone mimic Rimon Novaluron Oberon Spiromesifen Admire, Provado Actara, Platinum, Assail Imidacloprid Thiamethoxamneonicotinoids Agree, Cutlass, Deliver, Dipel, Javelin, XenTari Bacillus thuringiensis variants IGR – chitin inhibitor, enters via ingestion Tetronic acid derivatives interfere with lipid biosynthesis Interferes with nerve endings, keeps nerve receptor channels open Protein toxin attaches to gut of insect causing rupture and death in 24-48 hours Lepidopteran larvae White flies, leaf hoppers Colorado potato beetle, mites, thrips, some Lepidoptera larvae Lepidoptera larvae, good on large beet armyworms. (Sterilizes whitefly adults and eggs) Immature: Whitefly, thrips, some Lepidoptera larvae Mites, whiteflies Sucking insects, i.e., aphids, whiteflies, some true bugs, etc. Colorado potato beetle, Japanese and cucumber beetles, many other chewing insects Many Lepidopteran larvae such as hornworm, cabbage looper, fruitworm, armyworms, etc.
