Description
Benzoximate is an acaricide used to control all stages of spider mites on pome fruit, stone fruit, citrus fruit, vines and ornamentals. It was commercialized in Japan in 1971 but discontinued there in 1998 and is currently registered only in Italy, South Korea, South Africa and Switzerland.
Chemical Properties
Pure product is white crystal. m.p. 73℃, vapor pressure <1.33×10-2Pa (4.53×10-4Pa (25℃). solubility at 20℃: benzene 650g/L, dimethylformamide 1460g/L, xylene 710g/L (1296g/L), ethanol 70g/L (93g/L), hexane 8g/L, acetone 980g /L (1440g/L); almost insoluble in water. Stable to acid, easy to decompose in strong alkali medium, decomposition or isomerization at about 80℃.
Uses
Benzoximate is an acaricide that inhibits fruit tree red spider mite Panonychys ulmi (Koch)[1].
Mode of action
The mode of action of benzoximate is not known. Resistance has been reported in citrus red mite, European red mite and twospotted spider mite.
Toxicity evaluation
Benzoximate is relatively non-toxic to mammals and fish, but is moderately toxic to predatory mites.
