Oxytropis ochrocephala legumin surface active agent and preparation method thereof

Abstract

The invention discloses an oxytropis ochrocephala legumin surface active agent and a preparation method thereof, relating to a formula of a plant oriented surface active agent and a preparation method thereof. The oxytropis ochrocephala legumin surface active agent comprises the following components in percent by mass: 30-40 percent of oxytropis ochrocephala extract, 56-66 percent of solvent, 1-3percent of preservative and 1-3 percent of antifreezer. The preparation method comprises the steps of: firstly adding the solvent in a blending kettle, heating, adding the oxytropis ochrocephala extract according to the proportion, stirring and dissolving; and sequentially adding the preservative and the antifreezer according to the proportion, fully stirring and uniformly mixing to obtain the oxytropis ochrocephala legumin surface active agent. The oxytropis ochrocephala legumin surface active agent provided by the invnetion is a novel natural environmental-friendly type pesticide synergist,can be added in diluents of glyphosate, water-soluble pesticide, powder and wettable powder so that the adhesive property and the permeability of pesticide are improved through reducing surface tension of the pesticide, the pesticide retention of a target part is increased, the holding period and the rainwater washing resistance are prolonged, the effective utilization rate of the pesticide is increased, and the pesticide consumption and the water consumption are reduced.

Description

technical field [0001] The invention relates to a formulation of a plant source surfactant and a preparation method thereof. Background technique [0002] At present, the area of ​​chemical control in my country has reached 287 million hm 2 times, and is increasing by 13 million hm per year 2 Every year, 1 million tons of pesticide preparations and 100 million tons of liquid medicine are sprayed on farmland, but the effective utilization rate of pesticides is only 10%-30%, which is far lower than the average level of 50% in developed countries. Most of the pesticides are lost to the environment, which not only wastes a lot of pesticides, but also causes serious environmental pollution and poisoning of humans and animals. How to improve the effective utilization of pesticides and reduce the dosage of pesticides in non-target environments has become an urgent problem to be solved in my country's pesticide disciplines. The research on the rational use of pesticides is one of ...
