Abstract
The invention belongs to the technical field of pesticide adjuvants, and particularly relates to a synergist and application thereof. The effective components of the synergist comprise perfluorononyl polyethylene glycol ether and isomeric alcohol polyoxyethylene polyoxypropylene ether, the perfluorononyl polyethylene glycol ether comprises C9F17O (CH2CH2O) nH (perfluorononyl polyethylene glycol monoether) and C9F17O (CH2CH2O) nC9F17 (perfluorononyl polyethylene glycol diether), and n is in a range of 6 to 30; the number of PO in the isomeric alcohol polyoxyethylene polyoxypropylene ether is not more than 7. According to the synergist, the pesticide can have relatively balanced diffusivity and permeability through the matching effect of the effective components, the residual quantity of the pesticide on leaf surfaces can be reduced, the pesticide effect of the pesticide can be enhanced, the pesticide utilization rate can be increased, the synergist can enable pesticide liquid to be diffused to the whole leaf surfaces, permeate into plants and be absorbed by the plants, the pesticide damage is small, and the pesticide effect is good. The pesticide utilization rate is high and the pesticide effect is good.
Description
technical field [0001] The invention belongs to the technical field of pesticide adjuvants, in particular to a synergist and its application. Background technique [0002] The development of agriculture is inseparable from pesticides, but while pesticides make significant contributions to agricultural development, they also bring harm to the natural environment. Under the current situation of increasing population, decreasing land, increasing food demand, and increasingly severe environmental requirements, people need to develop more efficient and safe new pesticides; however, new pesticides have a long development cycle, large investment and high risks. , The success rate is low, especially the modern high-efficiency and ultra-high-efficiency pesticide varieties. Pesticide synergists have gradually played an important role in pesticides due to their simple composition, strong operability, and significant synergies when added in small amounts. [0003] Pesticide synergist ...
