Formulation: 40SC, 25EC, 25WP

Analysis: GC (TC, HG 2463. 1-93)

Packaging: 25kg/plastic woven bag or cardboard drum lined with plastic bag

Applications:
1) Biochemistry: probable chitin synthesis and prostaglandin inhibitor. Hormone disturbing
effect, leading to suppression of ecdysis.
2) Action: persistent insecticide and acaricide with contact and stomach action;
not translocated in the plant. Inhibits molting of nymphs and larvae, leading to
death. Also suppresses oviposition by adults; treated insects lay sterile eggs.
3) Uses:
a) Insecticide with persistent larvicidal action against Homoptera, some Coleoptera
and also Acarina
b) Effective against Cicadellidae and Delphacidae (leafhoppers) in rice; Cicadellidae
in potatoes; Aleyrodidae (whitefly) in citrus, cotton and vegetables; Coccidae,
Diaspididae (scale insects) and Pseudococcidae (mealy bugs) in citrus.

female mice >1000mg/kg
2) Skin and eyes: acute percutaneous LD50 for rats >5000mg/kg. Mild skin
irritant (guinea pigs), not irritating to skin and eyes (rabbits)
3) Inhalation: LC50 (4h) for rats >4.57mg/L air
4) NOEL: for male rats 0.90, female rats 1.12mg/kg daily
5) ADI: 0.01mg/kg b.w.
6) Fish: LC50 (48h) for carp 2.7, rainbow trout >1.4mg/L
7) Bees: no direct effect on bees at 2000mg/L (WP formulation)
8) Other: no effect on various predators, non-carcinogenic, non-mutagenic
