Embodiment 1

[0041] The composition of 10% oligosaccharin and chlorfenapyr suspension concentrate is composed of the following mass percentages (the mass ratio of oligosaccharin and chlorfenapyr is 1:1):

[0042] Amino oligosaccharin 5%, chlorfenapyr 5%, sodium lignosulfonate 8%, xanthan gum 0.20%, polyether modified polysiloxane defoamer 0.20%, bentonite 2%, sorbic acid 0.2%, lemon Acid 2%, urea 5%, sodium 1-naphthalene acetate 0.50%, deionized water to make up to 100%.

[0043] Preparation method: According to the formula, weigh the above components according to the proportion of the components, add a certain amount of original medicine, dispersing wetting agent, defoamer, and water into the mixing tank, stir evenly, and shear for 30 minutes (2200rpm) , and finally put it into a sand mill at 1800r / min for 2 hours, then discharge the material, and filter to obtain the finished product of 10% oligosaccharin and chlorfenapyr suspension concentrate.

Embodiment 2

[0045] The composition of 21% oligosaccharin and chlorfenapyr suspension concentrate is composed of the following mass percentages (the mass ratio of oligosaccharin and chlorfenapyr is 3:4):

[0046] Amino oligosaccharin 9%, chlorfenapyr 12%, EO / PO block copolymer 10%, xanthan gum 0.20%, polyether modified polysiloxane defoamer 0.20%, bentonite 2%, sorbic acid 0.2 %, citric acid 2%, urea 5%, 1-sodium naphthalene acetate 0.50%, and deionized water to make up to 100%.

[0047] Preparation method: According to the formula, weigh the above components according to the proportion of the components, add a certain amount of original medicine, dispersing wetting agent, defoamer, and water into the mixing tank, stir evenly, and shear for 30 minutes (2200rpm) , and finally put it into a sand mill for 2 hours of grinding at 1800r / min, discharge the material, and filter to obtain the finished product of 21% oligosaccharin and chlorfenapyr suspension concentrate.

Embodiment 3

[0049] The composition of the 14% oligosaccharin and chlorfenapyr suspension concentrate is composed of the following mass percentages (the mass ratio of oligosaccharin and chlorfenapyr is 2:5):

[0050] Amino oligosaccharin 4%, chlorfenapyr 10%, sodium lignosulfonate 8%, xanthan gum 0.20%, polyether modified polysiloxane defoamer 0.20%, bentonite 2%, sorbic acid 0.2%, lemon Acid 2%, urea 5%, sodium 1-naphthalene acetate 0.50%, deionized water to make up to 100%.

[0051] Preparation method: According to the formula, weigh the above components according to the proportion of the components, add a certain amount of original medicine, dispersing wetting agent, defoamer, and water into the mixing tank, stir evenly, and shear for 30 minutes (2200rpm) , and finally put it into a sand mill at 1800r / min to grind for 2 hours, discharge the material, and filter to obtain the finished product of 14% oligosaccharin and chlorfenapyr suspension concentrate.

Abstract

The embodiment of the invention relates to an insecticidal and bactericidal composition and application thereof, and relates to the field of pesticides. The active ingredients of the insecticidal and bactericidal composition comprise amino-oligosaccharin and chlorfenapyr, and the weight ratio of the amino-oligosaccharin to the chlorfenapyr is 1: 99-99: 1, optionally 1: 5-5: 1, optionally 1: 1-3: 4, and optionally 1: 1. The insecticidal and bactericidal composition disclosed by the invention can be used for preventing and treating insect pests and diseases of crops, and can effectively reduce the labor intensity. The composition shows a synergistic effect in the proportioning range, effectively reduces the use dosage of the active ingredients, reduces environmental pollution; and compared with a traditional single compound medicament, the composition has the advantages of wider pest control spectrum, stronger synergistic effect, lower use dosage and lower pest resistance development level.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an insecticidal and fungicidal composition and its application. Background technique [0002] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] For traditional pest control in agriculture, emamectin benzoate, cypermethrin, chlorpyrifos, phoxim, and chlorpyrifos are commonly used drugs for prevention and control. For diseases caused by crop fungi, saccharin, mancozeb, chlorothalonazim, streptomycin, etc. are generally used. [0004] However, if all the above-mentioned pesticides are used to control pests and diseases at the same time, not only the control effect is poor, but also drug resistance is easy to occur, and it...
