Embodiment 1

[0028] Cyclopyrid 25%, calcium lignosulfonate 5%, sodium lauryl sulfate 2%, sodium carbonate 2%, white carbon black 6%, kaolin supplemented to 100% by weight percentage, calcium lignosulfonate Coarse pulverization is carried out first, each component is mixed according to the weight ratio, and then pulverized in a jet mill to 3-15 μm, and the obtained 25% cyclopyrid wettable powder is obtained.

Embodiment 2

[0030] Cyclopyrid 50%, calcium lignosulfonate 4%, sodium alkylnaphthalene sulfonate 3%, sodium bicarbonate 4%, white carbon black 8%, kaolin supplemented to 100% by weight percentage, lignosulfonic acid Calcium is coarsely pulverized first, each component is mixed according to the weight ratio, and then pulverized in a jet mill to 3-15 μm, and the obtained is 25% cyclopyrid wettable powder.

Embodiment 3

[0032] Cyclopyrid field efficacy test:

[0033] With the 25% cyclopyrid wettable powder of embodiment 1 with 15g.ai / hm 2 、30g.ai / hm 2 、60g.ai / hm 2 To control rice planthoppers, respectively investigate the control effect on rice planthoppers 1 day, 3 days, 7 days, and 15 days after the application of the pesticide. The results of the investigation are compared with the control pesticides. The results are shown in Table 1. Pyridium WP has a good control effect on brown planthopper in rice fields, and has a long lasting effect. 25% cyclopyrid WP60g a.i. / hm 2 The corrected control effect was 70.97% 1 day after application, 93.08% 7 days after application, and 92.42% 15 days after application. Compared with 25% pymetrozine WP90g a.i. / hm 2 The control effect was equivalent and significantly higher than other control treatments. 25% Cyclopyrid WP is safe for rice growth.

Abstract

The invention discloses cycloxaprid wettable powder and a preparation method thereof, belonging to the field of pesticides. The cycloxaprid wettable powder comprises the effective ingredient of cycloxaprid and is prepared by the following steps: adding a wetting agent, a dispersant, a pH regulator and a carrier, uniformly mixing, and carrying out jet milling to obtain the powder with the fineness of 3-15 um as required. The cycloxaprid wettable powder disclosed by the invention is one of cycloxaprid agricultural preparations and has the advantages of high pesticide effect, low production cost, convenience for metering, safety in use, simple preparation process, easiness for implementation and the like.

Description

technical field [0001] The invention relates to a cyclopyrid formulation and a preparation method thereof, in particular to a cyclopyrid wettable powder 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...
