Brassinolide is an alias for brassinolide .
The research team of Zhejiang University, Yu Jingquan, found that a hormone in the plant, brassinolide, can help itself degrade pesticides, and accelerate the degradation rate after artificial application. This provides a new way to solve the problem of pesticide residues in agricultural products.
The researchers found that pesticides are slowly "digested" by themselves after being absorbed by plants. When the content of brassinolide in plants increases, many genes involved in the degradation of pesticides become active. The proteases synthesized under the guidance of these genes can gradually convert pesticides into water-soluble substances or low-toxic and non-toxic substances. Even directly excreted.
Experiments on various crops such as tomato, cucumber, Chinese cabbage and tea showed that before spraying carbendazim, chlorothalonil and chlorpyrifos, a small amount of brassinolide was sprayed, and the pesticide residue after harvesting was higher than that of the same period. Those who are not sprayed are reduced by 30% to 70%. Currently, brassinolide can be mass-produced by artificial semi-synthesis, and it does not harm humans, animals and plants.
