Insecticide acephate, also called ortran, the pure product is white crystal with melting point 90 ℃. For industrial product, the physical property is white solid with purity 80-90% and specific gravity 1.35. With regard to solubility, this product is soluble in fusible polarity solvents such as water, methanol, ethanol, acetone, methylene chloride, dichloroethane and other halogenated hydrocarbons but it is insoluble in benzene and toluene. And it has the effect of stomach and contact poisoning as well as fumigation and it can kill eggs.

  • Insecticide Acetamiprid As a new type of agricultural pesticide, insecticide acetamiprid belongs to nitro-methyl heterocyclic compounds. And the chemical name for this product is N-[(6-chloro-3-pyridyl)methyl]-N'-cyano-N-methyl-acetamidine. The mechanism for this product is to act on nicotinic acetylcholine receptors in the insect nervous system synapses, interfere obstruction pathway and cause accumulation of the neurotransmitter acetylcholine in the synapses...
  • Insecticide Chlorpyrifos-ethyl Insecticide chlorpyrifos-ethyl has medium toxicity and it is highly toxic to fish and aquatic organisms but it is less toxic to bees. The residue period on leaves is 5-7 days and that is much longer in soil. For most crops, there is no toxicity, but it is more sensitive to tobacco and tomato foliar spray. Compared with conventional pesticides, it has lower toxicity to natural enemies, so it can be taken as alternative to highly toxic organophosphorus pesticides...
