Embodiment 1

[0027] Example 1 : 5% Bacillus thuringiensis Chlorantraniliprole suspension concentrate.

[0028] According to Bacillus thuringiensis 3%, chlorantraniliprole 2%, mineral oil (solvent) 8%, naphthalene (penetrant) 2%, sodium methylnaphthalenesulfonate formaldehyde condensate (dispersant) 3%, Nongru 0203B ( Surfactant) 4%, white carbon black (filler) 4%, xanthan gum (stabilizer) 0.1%, ethylene glycol (antifreeze) 3%, tributyl phosphate (defoamer) 1%, to 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 5% Bacillus thuringiensis·chlorantraniliprole suspension.

Embodiment 2

[0030] Example 2 : 10% Bacillus thuringiensis Chlorantraniliprole wettable powder.

[0031] According to Bacillus thuringiensis 2%, chlorantraniliprole 8%, 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 10% Bacillus thuringiensis·chlorantraniliprole wettable powder.

Embodiment 3

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

[0034] Use 5% Bacillus thuringiensis · chlorantraniliprole suspension concentrate (Example 1) to control Plutella xylostella, apply the pesticide when the larvae of Plutella xylostella are in full bloom, and spray evenly with water. 32000IU / mg Bacillus thuringiensis wettable powder and 20% chlorantraniliprole 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 Bacillus thuringiensis and chlorantraniliprole. The pesticide composition comprises common aids, Bacillus thuringiensis and chlorantraniliprole; wherein the weight part ratio of Bacillus thuringiensis to chlorantraniliprole is 20:1-1:20; and Bacillus thuringiensis and chlorantraniliprole account for 1 to 60 percent of the weight of the pesticide composition. The aid is one or more of the following agents: solvent, an emulsifier, a wetting agent, a stabilizer, a dispersant, a thickener, a PH regulator, an anti-foaming agent, an antifreezer, and a filler. The pesticide composition is used for controlling Lepidoptera pests on crops, and is quick in response and long in persistence compared with a single agent; and the pesticide dosage and the cost are reduced, and environmental protection and comprehensive control over crop pests are facilitated.

Description

technical field [0001] The pesticide composition involved in the present invention uses Bacillus thuringiensis and chlorantraniliprole 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 co...
