Uses
Acaricide, insecticide.
Uses
Broad-spectrum acaricide used against adult mites, eggs and larvae. Also used as an insecticide against cockroaches, cotton bollworm, cotton budworm, and other pests.
Definition
Ovicide, insecticide, and miticide designed for use on cotton and vegetable crops. Available in a concentrated emulsion form, it is stated to be less toxic than organophosphates and is biodegradable.
Hazard
Questionable carcinogen.
Safety Profile
Poison by ingestion, skin contact, and intraperitoneal routes. Experimental reproductive effects. Human mutation data reported. An eye irritant. Questionable carcinogen with experimental carcinogenic data. When heated to decomposition it emits very toxic fumes of NOx and Cl-.
Environmental Fate
Plant. Principal soil and/or plants metabolites are p-chloro-o-toluidine, N′-(4-chloroo-tolyl)-N-methylformamidine (desmethylchlorphenamidine) and N-formyl-p-chloro-otoluidine (Verschueren, 1983). p-Chloro-o-toluidine, N′-(4-chloro-o-tolyl)-N-methylformamidine (desmethylchlor phenamidine) and N-formyl-p-chloro-o-toluidine were identified in rice grains and straws at concentrations of 3–61, 0.2–1, 10–38 and 80–6,900, 10–180, 67–500 ppb, respectively (Iizuka and Masuda, 1979).
Witkonton and Ercegovich (1972) studied the transformation of chlordimeform in six different fruits following foliar spray application. They found 4′-chloro-o-formotoluidide was the only major metabolite identified in apples, pears, cherries, plums, strawberries and peaches.
Chemical/Physical. Reacts with acids forming soluble salts (Hartley and Kidd, 1987).
Emits toxic fumes of nitrogen oxides and chlorine when heated to decomposition (Sax and Lewis, 1987).
