Pesticides development direction: highly toxic, high residue pesticide variety and scope will be further limited by Zhejiang wheat modifiers, and efficient, low toxicity, environmentally friendly and easy to produce will be more resistant to pesticides to the more widely used. The resulting intermediate is highly toxic pesticides product life cycle has ended or entered a recession wheat modifiers, and new insecticides intermediate because of its downstream products with high efficiency, low toxicity and residue characteristics Luoyang wheat regulator, is in growth, profits more lucrative. Pesticides Category: Press sources. Inorganic and mineral pesticides. Such as lead arsenate, arsenic, calcium fluoride, sodium and mineral oil emulsions. Such pesticides are generally low efficacy, crop can lead to injury, while arsenic trioxide on human toxicity. Therefore, since the heavy use of pesticides in organic synthesis it has been largely eliminated.
