Embodiment 1

[0023] Cyclopyrid 10%, sodium lignosulfonate 3%, sodium lauryl sulfate 2%, ethylene glycol 5%, sodium bicarbonate 3%, aluminum magnesium silicate 0.8%, organic silicon 0.2% by weight percentage %, water supplemented to 100% mixed shear, and sanded in a sand mill to an average particle size of 2-3 microns to obtain the preparation of the present invention.

Embodiment 2

[0025] Cyclopyrid 25%, sodium lauryl polyoxyethylene sulfate 3%, sodium lignosulfonate 3%, propylene glycol 4%, sodium carbonate 2%, xanthan gum 0.5%, organic silicon 0.2% by weight percentage, Make up water to 100% mixing and shearing, and grind to an average particle size of 2-3 microns in a sand mill to prepare the preparation of the present invention.

Embodiment 3

[0027] Cyclopyrid field efficacy test:

[0028] With the 10% cyclopyrid suspending agent of embodiment 1 with 15g.ai. / hm 2 、30g.ai. / hm 2 、60g.ai. / hm 2 To prevent and control rice brown planthopper, respectively investigate the control effect on rice brown planthopper after 1 day, 3 days, 7 days, and 14 days of application. The results of the investigation are compared with those of the control agent. Tests show that 10% cyclopyrid suspension concentrate has good control effect on rice brown planthopper, its quick effect and control effect are better than that of the control agent, and its persistent effect is equivalent to that of the control agent. The drug is safe to rice.

Abstract

The invention discloses a cycloxaprid suspending agent and a preparation method thereof, belonging to the field of pesticides. The cycloxaprid suspending agent comprises the effective ingredient of cycloxaprid and is prepared by the following steps: adding a wetting dispersant, a thickener, an anti-freezing agent, a pH regulator, an antiseptic agent, a defoaming agent and water, and carrying out sand grinding in a sand grinder till the average grain diameter is 2-3 micrometers, thus obtaining the suspending agent. The cycloxaprid suspending agent disclosed by the invention is an environment-friendly water-based preparation and has the advantages of reduced pollution to the environment and improved pesticide effect on crops.

Description

technical field [0001] The invention relates to a cyclopyrid formulation and a preparation method thereof, in particular to a cyclopyrid suspension and a preparation method thereof. Background technique [0002] Cyclopyrid is an agricultural insecticide with high activity and low toxicity researched and invented by East China University of Science and Technology. Cyclopyrid is highly effective against Homoptera pests, and also has a concurrent control effect on Lepidoptera pests, especially against the major rice pest brown planthopper and the alien invasive pest Bemisia tabaci. In addition, it can also be used for cabbage aphids , Plutella xylostella, rice leaf roller and other pests. At present, the synthesis and application of cyclopyrid have been applied for Chinese invention patent and international PCT patent, but there is no related report about the formulation of cyclopyrid. Contents of the invention [0003] One of the technical problems to be solved by the pres...
