Carbaryl CAS 63-25-2 1-Naphthyl-N-methylcarbamate
Carbamate insecticide (CAS 63-25-2) is a representative variety of carbamate insecticides, featuring both high efficiency and environmental degradability. However, it is necessary to pay attention to its toxicity to bees and its instability in alkaline conditions.

Physical and chemical properties
Appearance: Pure product is white crystal, while industrial product is light yellow powder.
Melting point: 142°C (stable to light and heat).
Solubility: Slightly soluble in water, readily soluble in organic solvents (such as toluene, acetone).
Stability: It rapidly decomposes upon contact with alkali, generating 1-naphthol and thus becomes ineffective.
Carbamate insecticide (CAS 63-25-2) is a representative variety of carbamate insecticides, featuring both high efficiency and environmental degradability. However, it is necessary to pay attention to its toxicity to bees and its instability in alkaline conditions.
Insecticide uses:
It has contact killing and stomach toxicity effects, and also has a slight systemic property.
The pests to be controlled include over 160 species such as Lepidoptera (such as cotton bollworms and leaf-rolling moths), Diptera (such as mosquitoes and flies), Coleoptera (such as valley bores), etc.
It is widely used in fruits, vegetables, cotton, rice and other crops.
Features
It has strong selectivity and has a relatively small impact on natural enemy insects.
It still maintains high activity in low-temperature environments and is especially suitable for pest control in early spring.
