Embodiment 1

[0025] Example 1 (11% indoxacarb metaflumizone EC)

[0026] Indoxacarb 10%, metaflumizone 1%, non-ionic polyoxyethylene ether 4%, epoxidized soybean oil 1%, p-aminobenzoic acid 0.5%, emulsifier 1601#10%, emulsifier 500# 5%, the balance is ethanol and xylene. Add the above formulas into the blending kettle in sequence according to the proportion, and after stirring evenly, 11% indoxacarb·metaflumizone EC can be prepared.

[0027] This embodiment is applied to control rice leaf roller. 11% indoxacarb metaflumizone EC was sprayed evenly with water at 12 g / mu in the hatching stage of rice leaf roller eggs. %, 98.6%. Contrast single dose 15% indoxacarb suspension concentrate (application rate is 10 grams / mu), single dose 10% metaflumizone suspension concentrate (application rate is 170 grams / mu) is sprayed in the same way, after the medicine 1 The control effects after 1 day were 80.8%, 83.1%, 89.2%, 90.7% after 7 days, and 94.3%, 92.6% after 15 days. After mixing indoxacarb a...

Embodiment 2

[0028] Embodiment 2 (6% indoxacarb metaflumizone microemulsion)

[0029] According to indoxacarb 5%, metaflumizone 1%, emulsifier 602 5%, emulsifier NP-10 5%, emulsifier 500# 5%, cyclohexanone 5%, xylene 5%, the balance is to ionized water. Dissolve the original drug, solvent and emulsifier in the above formula into a uniform oil phase, slowly add it into deionized water under stirring, then rapidly invert the phase after stirring and heating, and cool to room temperature to prepare 6% indoxacarb metaflumizone micro emulsion.

[0030] This embodiment is applied to control cotton bollworm. 6% indoxacarb·metaflumizone microemulsion was sprayed evenly with water at 25 g / mu at the peak of the occurrence of young larvae of cotton bollworm, and the control effects were 86.3% and 92.2% on 1 day, 7 days and 15 days after spraying , 96.5%. Contrast single dose 15% indoxacarb suspension concentrate (application rate is 10 grams / mu), single dose 10% metaflumizone suspension concentra...

Embodiment 3

[0031] Example 3 (30% indoxacarb metaflumizone suspension concentrate)

[0032]Indoxacarb 15%, metaflumizone 15%, emulsifier 1601# 10%, wetting agent LS 5%, dispersant SOPA-2704%, bentonite 2%, xanthan gum 0.1%, silicone defoamer 0.4%, glycerin 5%, and the balance is deionized water. The above formula is pre-crushed according to the proportion, and then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 30% indoxacarb-metaflumizone suspending agent.

[0033] This embodiment is applied to control Plutella xylostella. 30% indoxacarb metaflumizone suspending agent was sprayed evenly with water at 5 g / mu in the peak hatching stage of diamondback moth eggs, and the control effects were 94.3%, 98.0%, 15 days after spraying, respectively 100%. Contrast single dose 15% indoxacarb suspension concentrate (application rate is 10 grams / mu), single dose 10% metaflumizone suspension concentrate (application rate is 170 grams / mu) is sprayed in the sa...

Abstract

The invention discloses a pesticidal composition containing indoxacarb and metaflumizone, which comprises commonly used additive, the indoxacarb and the metaflumizone, the weight part ratio of the indoxacarb to the metaflumizone is 10:1 to 1:20, and the total weight of the indoxacarb and the metaflumizone accounts for 5 percent to 80 percent of the pesticidal composition. The additive is one or more of solvent, emulsifier, wetting agent, stabilizer, dispersing agent, thickening agent, pH regulator, defoamer, antifreeze and filler. The pesticidal composition is used to control the lepidoptera pests of crops. The pesticidal composition is better than units in terms of quick action and persistence, moreover, the dosage of pesticide is reduced, the use cost of pesticide is reduced, and the pesticidal composition is favorable for environment protection and comprehensive agricultural pest control.

Description

technical field [0001] The insecticidal composition involved in the present invention uses indoxacarb 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 pesticid...
