Embodiment 1-5

[0040] Embodiment 1 is taken as an example below for description.

Embodiment 1

[0042] Composite insecticide is prepared according to the following steps in embodiment 1:

[0043] (1) 80kg of poisonous agent and 450kg of deionized water are prepared into a mixed solution, wherein the poisonous agent is mixed with spinosad and Bacillus thuringiensis powder according to the weight ratio of 1:2;

[0044] (2) 150kg kaolin and 60kg expansion agent are mixed uniformly to obtain a mixed powder, and the mixed solution is sprayed in the mixed powder for 10 times, and the mixed powder is dried immediately after each spraying, and the expanded powder is obtained after the mixed solution is exhausted; wherein, The expansion agent is made by mixing nano-iron powder and calcium-based bentonite according to the weight ratio of 1:2.2;

[0045] (3) Mix 60kg of shortening, 60kg of soybean dregs, 140kg of corn flour, 60kg of glycerin, and 24kg of alcohol evenly, then dry and pulverize the mixture to obtain an attractant, and mix the expansion powder with the attractant at a...

Embodiment 14

[0056] The difference between this example and Example 11 is that the expansion powder also includes 16 kg of quartz powder, and the quartz powder is mixed with the dried mixed powder in step (2) to obtain the expansion powder.

[0057] As shown in Table 4, the difference between Examples 14-18 mainly lies in the different amounts of quartz powder.

Abstract

The invention relates to the technical field of pesticides, and particularly discloses a composite pesticide and a preparation method thereof. The composite insecticide is formed by mixing swelling powder and an attractant according to the weight ratio of (1.2-1.6): 1, and the swelling powder comprises the following components in parts by weight: 150-250 parts of kaolin, 60-80 parts of a swelling agent and 80-120 parts of a poisoning agent. The swelling powder provided by the invention can destroy the peritrophic film of lepidoptera pests, thereby reducing the obstruction of the peritrophic film on the diffusion of the poisoning agent and improving the insecticidal efficiency of the composite insecticide.

Description

technical field [0001] The application relates to the technical field of pesticides, more specifically, it relates to a composite pesticide and a preparation method thereof. Background technique [0002] Lepidoptera is the second largest order of insects after Coleoptera. The larvae of Lepidoptera insects mostly feed on various plants. Common agricultural pests such as cabbage cabbage butterfly, cotton bollworm, American white moth and soybean borer belong to the scale Pteroptera. In the digestive tract of Lepidoptera insects, there is a peritrophic membrane composed of chitin and protein. After the Lepidoptera insects eat, the peritrophic membrane wraps the food in the digestive tract. The residue is excreted together. [0003] There is a compound insecticide in the related art, which is compounded by powder and attractant according to the weight ratio of (8-10): 3, wherein the attractant is shortening, and the powder includes the following components by weight: 16-24 pa...
