ECOTOXICOLOGY
Birds Acute oral LD50 for Japanese quail >2000 mg/kg. Dietary LC50 (8 d) for Pekin ducks 600, Japanese quail 1000 mg/kg diet. Fish LC50 (96 h) for rainbow trout 0.35, bluegill sunfish 0.5, carp 2.4 mg/l. Daphnia LC50 (48 h) 0.17 mg/l. Algae EC50 (72h) for Scenedesmus subspicatus >52 mg/l. Bees Not toxic to bees; LC50 (24 h) 183 mg/bee. Worms LC50 (14 d) for earthworms >1000 mg/kg soil. Other beneficial spp. Safe on the relevant adult and immature stages of anthocorids, mirids, coccinellids, Chrysopa, Hemerobius, staphylinids, carabids, syrphids and dolichopodids in deciduous fruits, citrus and hops. The potential hazard to predatory mites can be minimised by avoiding early season sprays.
ENVIRONMENTAL FATE
Animals Bromopropylate is rapidly and efficiently eliminated in animals. Metabolism occurs by cleavage of the isopropyl ester and, to a minor extent, by oxidation. Metabolites formed after oxidation were 3-hydroxybenzilate and conjugates. Plants Studies with 14C-labelled bromopropylate showed little penetration into leaves or fruit. Degradation was slow. Soil/Environment The principal metabolite in soil is 4, 4-dibromobenzilic acid. For details of persistence in soil, see J. Environ. Qual., 1973, 2, 115. DT50 c. 40-70 d (lab. And field studies). Low mobility in soil.
