Carbaryl is often inexpensively produced by direct reaction of methyl isocyanate with 1-naphthol. [5]C 10 H 7 OH + CH 3 NCO → C 10 H 7 OC(O)NHCH 3. Alternatively, 1-naphthol can be treated with excess phosgene to produce 1-naphthyl chloroformate, which is then converted to carbaryl by reaction with methylamine. [5]
Sevin, (b) Sevin XLR Carbamate: High risk to bees foraging even 10 hours after spraying; 3 – 7 days (b) 8 hours @ 1.5 lb/acre (1681 g/Ha) or less.
