market prospect


The scale insect is a small insect. There are more than 6000 species of scale insects in the world, and about 650 species are recorded in China. Scale insects are the most common pests in flowers and fruit trees. They have strong reproductive ability and often cluster on branches, leaves and fruits.


Adults and nymphs insert needle-shaped mouthparts into crop tissues to absorb juice, causing wilt of branches and leaves, and even the whole plant to die; in addition, the secretion of scale insects can also cause soot disease, causing great harm. Scale insects have strong resistance to drugs, and it is difficult for general agents to enter the body.


Methamidophos is the main pesticide to kill scale insects at present, but methamidophos belongs to high toxic organophosphorus pesticides. With the banning of high toxic pesticides by the Ministry of Agriculture and other five ministries and commissions, methamidophos is bound to be eliminated, and azotenamide will become one of the important substitutes for methamidophos.




Azolidinamide is a new pyrazole heterocyclic insecticide and acaricide. Its main mechanism of action is to prevent the oxidative phosphorylation of insects. It also has the functions of killing eggs, inhibiting feeding, inhibiting oviposition and sterilizing.
