Pesticides development direction: highly toxic, high residue pesticide variety and scope will be further restricted, and efficient, low toxicity, environmentally friendly and less resistant to insecticides will be more widespread Applications. The resulting intermediate is highly toxic pesticides product life cycle has ended or entered a recession, while the new pesticide intermediates downstream products due to its high efficiency, low toxicity and residue characteristics Xinxiang corn dedicated regulator agent, is in growth, profits more lucrative. Insecticide: nerve agent site of action. Stimulation by sensory neurons and action by the transducer into electrical signals Zhoukou corn dedicated regulator, this electrical signal is converted in the body of the nerve cell axons junction nerve impulses special regulator Zhejiang corn, the form of pulses along the axis sudden delivery to the central nervous system. Axonal conduction in the nervous system are present, it is the site of action of DDT, pyrethrins, tetrodotoxin and other nerve agents, it is known as the second part of the class action.
