Abstract

The invention discloses a tolfenpyrad suspending agent for preventing and controlling empoasca pirisuga matumura of tea trees and a preparation method thereof and relates to the technical field of prevention and control of empoasca pirisuga matumura of tea trees. The tolfenpyrad suspending agent is prepared at least from 30 parts of tolfenpyrad, 8 parts of sodium lignin sulfonate, 5 parts of fatty alcohol-polyoxyethylene ether, 0.5 part of xanthan gum, 5 parts of ethylene glycol, 0.5 part of organic silicone and the balance of water based on 100 parts in total. The preparation method comprises the following steps: feeding all raw materials into a preparation kettle and mixing and stirring; performing primary grinding with a colloid mill and then fine grinding with a sand mill; sampling and analyzing; and if the sample is qualified, filtering, metering, packaging and storing. In the invention, by reasonably designing the dosage form of the product and the proportion of the raw materials, the prevention and control effect of the prepared 30% tolfenpyrad suspending agent on empoasca pirisuga matumura of tea trees is obvious in comparison with the pesticides of other dosage forms or the crude pesticide of tolfenpyrad.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of tea tree green leafhoppers, in particular to a tolfenpyrad suspending agent used for the prevention and treatment of tea tree green leafhoppers and a preparation method thereof. Background technique [0002] At present, the existing insecticides used to prevent and control tea leafhoppers, for example, Chinese patent "CN103814930A" discloses an "insecticidal composition containing thiacloprid and diafenthiuron", in which thiacloprid The weight ratio of diafenthiuron and diafenthiuron based on the active component is preferably 1:1 to 1:20. Another Chinese patent "CN103250719A" discloses a "insecticidal composition with synergistic effect", the active ingredients are diafenthiuron and pichridam, and the mass ratio of the two is 40:1-1:50. [0003] The inventor has verified through long-term experiments that the above-mentioned several insecticidal compositions mainly have the f...
