Pymetrozine is a picolinimines or triazinone insecticide. It is a non-biocidal insecticide. It was first developed by Ciba-Geigy of Switzerland in 1988. This product has an impact on a variety of crops. Sucking mouthparts pests show excellent control effects. Pymetrozine has contact killing effect on pests and also has systemic activity. In plants, it can be transported in both the xylem and the phloem; therefore, it can be used as a foliar spray or soil treatment. Due to its good transport characteristics, the newly grown branches and leaves can also be effectively protected after the stems and leaves are sprayed.
Research using electro-penetration graph (EPG) technology shows that, whether it is dripping, feeding or injection test, as long as aphids or planthoppers come into contact with pymetrozine, the stylus blocking effect will occur almost immediately, and the feeding will be stopped immediately, and finally starvation. Fatal, and the process is irreversible. Therefore, pymetrozine has an excellent function of blocking insect transmission. Although the mechanism of stylus obstruction caused by pymetrozine is not clear, existing studies have shown that this irreversible "stopping" is not caused by "antifeeding effect". The initial mortality of insects treated with pymetrozine is very low, and the insect "hungry moth" can survive for several days before it dies, and the mortality rate is related to climatic conditions. Experiments show that within 3 hours of treatment with the chemical, the feeding activity of aphids is reduced by about 90%, and the mortality rate can be close to 100% after 48 hours of treatment.
