Embodiment 1

[0027] Example 1 : 20% Bacillus thuringiensis · metaflumizone suspension concentrate.

[0028] According to Bacillus thuringiensis 2%, metaflumizone 18%, mineral oil (solvent) 10%, naphthalene (penetrant) 2%, methyl naphthalene sulfonate sodium formaldehyde condensate (dispersant) 5%, agricultural milk 0203B (surface Active agent) 6%, white carbon black (filler) 4%, magnesium aluminum silicate (stabilizer) 0.5%, ethylene glycol (antifreeze) 3%, tributyl phosphate (defoamer) 1.5%, detox Make up to 100% with ionized water.

[0029] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 20% Bacillus thuringiensis · metaflumizone suspension concentrate.

Embodiment 2

[0030] Example 2 : 20% Bacillus thuringiensis · metaflumizone wettable powder.

[0031] According to Bacillus thuringiensis 5%, metaflumizone 15%, fatty alcohol polyoxyethylene ether (penetrant) 2%, sodium lauryl sulfate (surfactant) 2%, white carbon black (filler) 8%, Sodium lignosulfonate (dispersant) 5%, bentonite (filler) to make up to 100%.

[0032] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 20% Bacillus thuringiensis Metaflumizone wettable powder.

Embodiment 3

[0033] Example 3 : Control efficacy test of Plutella xylostella.

[0034]Use 20% Bacillus thuringiensis · metaflumizone suspension concentrate (Example 1) to control Plutella xylostella, apply the pesticide at the peak growth stage of Plutella xylostella larvae, and spray evenly with water. 32000IU / mg Bacillus thuringiensis wettable powder and 24% metaflumizone suspension were used as control agents. A total of 4 pesticide treatments were set up in the test, and each treatment was repeated 4 times. The insect population base was investigated before spraying, and the control effect was investigated 3 days, 5 days, and 10 days after spraying. The test results are shown in Table 2.

[0035] Table 2. Results of field efficacy tests on controlling Plutella xylostella.

Abstract

The invention discloses a pesticide composition containing agritol and metaflumizone. The pesticide composition comprises common auxiliaries, the agritol and the metaflumizone, wherein the weight part ratio of the agritol to the metaflumizone is 20:1-1:20, and the weight sum of the agritol and the metaflumizone accounts for 1 to 60 percent of the weight percentage of the pesticide composition. The auxiliaries are one kind or several kinds of materials from solvents, emulsifying agents, wetting agents, stabilizing agents, dispersing agents, thickening agents, pH regulating agents, defoaming agents, antifreezing agents and fillings. The pesticide composition is used for preventing and treating crop lepidoptera type insects, and has the advantages that the quick acting effect and the persistence are better than those of single dosages, in addition, the use dosage of pesticide is reduced, the pesticide consumption cost is reduced, and the comprehensive treatment of environment protection and agricultural insects is favorably realized.

Description

technical field [0001] The pesticide composition involved in the invention uses bacillus thuringiensis and metaflumizone as active ingredients, and is used for preventing and controlling lepidopteran pests of crops. Background technique [0002] The problem of resistance to agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical pest control year after year, the increase in the use of pesticides and the unscientific use of pesticides, the resistance of pests is becoming more and more serious, and the types of resistant pests are increasing. Especially the lepidopteran pests that seriously damage agricultural production have a high degree of resistance and relatively fast development of resistance. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pestici...
