Melamine chemical structure: organophosphates, organochlorines, pyrethroids. Classification of uses: can be divided into insecticides, fungicides, acaricides, rodenticides, herbicides, specific agents and plant growth regulators. Source classification: The products of synthetic ammonia manufacturers can be classified into mineral pesticides, botanical pesticides, organic pesticides, and microbial pesticides. Insecticides usually have four modes of action to kill pests: contact, stomach poison, fumigation and systemic. The classification of dosage forms can be divided into old dosage emulsifiable concentrates, suspension concentrates, water emulsions, both concentrated emulsions and microemulsions, wettable powders, water-based dosage forms and water dispersible granules, etc.
