Embodiment 1

[0032] Example 1 4% phoxim·diflubenzuron microcapsule suspension

[0033] Step 1: phoxim 30g, diflubenzuron 10g, sebacoyl chloride 5.8g, polymethylene polyphenylene diisocyanate 2.2g to form A solution, 4% polyvinyl alcohol 600mL as B solution, diethylenetriamine 2.9g, Solution C was composed of 5.1 g of anhydrous sodium carbonate and 200 mL of deionized water. Put the B solution into the reactor and stir rapidly at 1500r / min, add the A solution to the B solution and immediately add the C solution, stir at 300r / min for 2 hours, and obtain a microcapsule slurry containing 40g of active ingredients.

[0034] Step 2: Adjust the microcapsule slurry to neutrality with 10% acetic acid aqueous solution, add 2.5g of emulsifier NP-10, 12g of xanthan gum, 0.5g of silicone defoamer, add deionized water to 1L, and obtain 4 % phoxim · diflubenzuron microcapsule suspension.

Embodiment 2

[0035] Example 2 4% phoxim·diflubenzuron microcapsules

[0036] The method of preparing microcapsules in this example is substantially the same as that in Example 1, the difference is that in step 2, the microcapsule slurry is adjusted to neutrality with 10% acetic acid aqueous solution, and 2 g of lubricating oil and 10 g of lignin sulfonate are added. Sodium phosphate, 8g bentonite, add clay to supplement to 1000g, and obtain 4% phoxim·diflubenzuron microcapsules by extrusion granulator.

Embodiment 3

[0037] Example 3 1% phoxim·chlorfluazuron microcapsule suspension

[0038]Step 1: phoxim 5g, chlorfluazuron 1g, polymethylene polyphenylene diisocyanate 0.8g, xylene 3mL to form A solution, 1% polyvinyl alcohol 40mL, ethylenediamine 0.5g and dodecanebenzenesulfonic acid 1g of sodium is used to form solution B, add solution B to solution A, stir in a high-shear emulsification tank at 2800r / min for 30 minutes, reduce the speed to 300r / min, heat up and encapsulate for 2 hours, and obtain a microcapsule slurry containing 6g of active ingredients .

[0039] Step 2: Adjust the microcapsule slurry to neutrality with 10% acetic acid aqueous solution, add 12g Nongru 500#, 10g dispersant D425 and 20mL ethylene glycol, add deionized water to make up to 600mL to prepare 1% phoxim fluoride pyridineurea microcapsule suspension.

Abstract

The invention belongs to the technical field of pesticide, and discloses a compound composition containing an organophosphorus insecticide and a chitin synthesized inhibitor and application of the compound composition. The compound composition is composed of the organophosphorus insecticide and the chitin synthesized inhibitor, and the mass ratio of the organophosphorus insecticide to the chitin synthesized inhibitor is 1:50 to 50:1. The organophosphorus insecticide is selected from one of phoxim, chlorpyrifos, dipterex, isofenphos-methyl and triazophos, the chitin synthesized inhibitor is selected from one of diflubenzuron, chlorbenzuron, chlorfluazuron, hexaflumuron, flufenoxuron, diafenthiuron and buprofezin. The organophosphorus insecticide and the chitin synthesized inhibitor are compounded; compared with a single-dosage organophosphorus insecticide, the prevention effect of preventing soil insects is improved; compared with the independently adopted organophosphorus insecticide,if the compound composite is reduced by 20%, a good prevention effect can still be achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a compound composition containing an organophosphorus insecticide and a chitin synthesis inhibitor and an application thereof. Background technique [0002] The control of larvae is not a new topic in the research field. However, the soil application environment is much more complicated than that of ordinary foliage spraying. The types of microorganisms in the soil are complex, and their catabolism will have a very serious impact on the activity and effective utilization of pesticides. After market selection, organophosphorus insecticides such as phoxim, chlorpyrifos, and trichlorfon, and neonicotinoid insecticides such as imidacloprid are the two most widely used pesticides in soil control. However, these two types of pesticides have exposed the problem of increasing pest resistance. In order to achieve the control effect, the amount of pesticides is increasing day by day, whi...
