Abstract

The invention discloses a preparation method of a tannic acid-modified leaf-adhesive pesticide, which belongs to the field of preparation of pesticide formulations. The method is to weigh a certain amount of pesticide and dissolve it in deionized water, stir it evenly to obtain solution A; prepare tannic acid solution B, prepare ferric chloride to obtain solution C; Add 1 mL of solution B dropwise; the solution system was magnetically stirred for 5 minutes, and 1 mL of solution C was slowly added dropwise to the above system in the same volume ratio of 100:1. When solution C was dropped in, the color of the solution quickly turned into sea blue. After the system reacted for 5 minutes, the solution was centrifuged at 6000 rpm for 10 minutes to obtain the leaf-adhesive pesticide. The invention uses environment-friendly materials to modify the surface of the water-dispersible granule pesticide particles to improve its adhesion to the crop leaf surface, thereby increasing the effective utilization rate of the pesticide. contribute.

Description

【Technical field】 [0001] The invention relates to a preparation method for modifying tannic acid to enhance the adhesion of pesticide leaves, in particular to a method for improving the anti-photolysis stability of pesticides on the basis of the original water-dispersible granule and nano-suspension formulation pesticide production, and enhancing the anti-photolysis stability of pesticides on plants. The invention relates to a method for leaf surface adhesion, which belongs to the field of preparation of pesticide formulations. 【Background technique】 [0002] Pesticides are also called agrochemicals or agricultural growth regulators. With the development of biotechnology, the emergence of insect-resistant varieties can reduce the use of pesticides to a limited extent. However, the total population of our country is still showing an increasing trend. Under the condition of no increase in the total cultivated land area, pesticides still play an irreplaceable role in today's a...
