Problems solved by technology

[0004] Reasonable compounding of the two, synergistic with each other, can achieve more excellent effects, but the absorption efficiency of plants after application of existing pesticide compositions is low, requiring high-concentration pesticide spraying or multiple application, resulting in resources Waste and unfriendly to the soil, and in the process of spraying, pesticides are prone to agglomeration, resulting in sedimentation, so that the concentration of pesticides is uneven and the efficacy of drugs cannot be better exerted;

Abstract

The invention discloses a composition containing propionyl brassinolide and hypersensitive protein. Maleic anhydride is added into a three-neck flask provided with a reflux condensing tube and a thermometer, polyethylene glycol monomethyl ether is added, magneton stirring is started, p-toluenesulfonic acid is added, an intermediate C is obtained, and the intermediate C and allyl benzene are added into a four-neck flask. The propionyl brassinolide and the hypersensitive protein are reasonably compounded, so that the growth of plants can be regulated, the growth of the plants is promoted, the yield of crops is increased, the stability of the pesticide is improved by adding the dispersing aid, the pesticide is not easy to settle, and the absorption efficiency of the plants is improved by adding the surface active aid, so that the purposes of high-efficiency pesticide use, environment protection and soil pressure reduction are achieved.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a composition containing propionylbrassinolide and hypersensitive protein. Background technique [0002] Phytohormones play an important role in the growth and development of plants. The growth and development of plants are regulated by applying hormones or growth-regulating substances outside the plant. For target plants, plant growth regulators are exogenous non-nutritive chemical substances that can It is transmitted to the action site in the plant body, and can promote or inhibit some links of its life process at a low concentration, so as to promote plant growth, increase crop yield, and increase crop stress resistance, etc.; [0003] Propionyl brassinolide is an upgraded product of the original brassinolide. It is a new type of high-efficiency plant growth regulator. In addition to retaining the advantages of the original brassinolide, its efficacy period is longer and the effect ...
