Problems solved by technology

[0002] Fluoride is a new type of benzoylurea insect growth regulator, which can prevent the synthesis of chitin in the molting stage of insects during the growth process, thereby affecting insect molting, so that pests cannot form new epidermis when molting, and the insect body It is deformed and dies. It can also regulate the growth and development of insects, inhibit molt metamorphosis, and inhibit the eating speed of pests. It has high ovicidal activity, but it has poor quick-acting properties and is ineffective against adults and eggs.
[0003] Abamectin, profenofos, lambda-cyhalothrin, and emamectin are relatively new chemical insecticides, which can be widely used in the control of cotton, vegetables, fruit trees, rice and other food crops pests and mites, such as cotton bollworm, diamondback moth, beet armyworm, cabbage caterpillar, Spodoptera litura, flea beetle, etc. However, most of them have disadvantages such as high dosage, narrow control spectrum, and rapid resistance generation when used alone
[0004] After testing, the above raw materials have strong complementary and synergistic effects. After reasonable compounding, the use cost is reduced, the toxicity is reduced, the insecticidal spectrum is expanded, the killing speed of pests is accelerated, and the resistance of pests is overcome and delayed. At present, my country's pesticide industry has not yet used the above raw materials to make pesticides

Embodiment 1

[0015] Example 1: Synergistic compounding of fluorohydryl urea and abamectin suspension

[0016] Choose suitable solvents, emulsifiers, prepare 10% fluorobenzamide EC, 5% abamectin EC; and prepare a mixture of abamectin and fluorobenzamide suspension, the mixture contains 2% avermectin ( 100% off), 5% fluorine urea (100% off), 10% of additives, and 100% water to make up 7% abamectin·fluorourethane suspension. Taking the third instar larvae of Plutella xylostella as the control object, the spot method was used to determine the indoor virulence of abamectin single agent, fluorine urea single agent and the mixture of the two on the third instar larvae of Chilo suppressalis. On this basis, the Sun Peiyun method was used to calculate the co-toxicity coefficient CTC value of the mixture. The specific measurement results are shown in Table 1.

Embodiment 2

[0020] Example 2: Field efficacy test of the mixture of fluorohydryl urea and profenofos EC

[0021] Choose appropriate solvents and emulsifiers, prepare 10% fluorouryl urea EC, 40% profenofos EC; and prepare a mixture of profenofos and fluorourethane, the mixture of fluorouryl urea 5%, profenofos 30% , Emulsifier 10%, solvent supplement to 100%, that is to configure 35% fluorine urea·Profenofos EC. The above three medicaments are used to control the cabbage diamondback moth at a dose of 20 g / mu, and the application method is sprayed. The specific control effect is shown in Table 2.

[0022] Table: Field efficacy test results of the mixture of difluoro urea and profenofos EC

[0023]

[0024] From the measurement data in Table 2, it can be seen that the quick-acting and lasting effect of the mixed profenofos and fluorourethane are higher than the two single-agents, and it shows a good insecticidal effect. It is an ideal medicament for controlling Plutella xylostella.

Embodiment 3

[0025] Example 3: Synergistic compounding of microemulsions of fluorohydantoin and lambda-cyhalothrin

[0026] Choose suitable solvents and emulsifiers, prepare 10% fluorourethane EC, 5% lambda-cyhalothrin microemulsions; and prepare a mixture of fluorourethane and lambda-cyhalothrin microemulsions. Cyfluthrin 2% (100% discount), Fluorouride 7% (100% discount), emulsifier 13%, solvent 18%, make up to 100% with deionized water, and use pesticide microemulsion processing technology to configure it into 9% Lambda-cyhalothrin·Fluorouride microemulsion. Using the method of soaking insects and soaking leaves, using the third-instar diamondback moth provided by the insect breeding room of Shandong Pesticide Research Institute as the test insects, the effect of lambda-cyhalothrin single agent, fluorine urea single agent and the mixture of the two on third-instar vegetables was determined. Indoor virulence of moths. On this basis, the Sun Peiyun method was used to calculate the co-toxic...

Abstract

The invention relates to a pesticide composition, especially a synergetic combined composition of a novel benzoyl urea insect growth regulator of novaluron and one or more compounds selected from abamectin, profenofos, lambda-cyhalothrin and methylaminoavermectin. According to the present invention, individual disadvantages of the above pesticides are overcome, a strong synergistic effect is provided, use cost is reduced, toxicity is reduced, insecticidal spectrum is developed, kill speed of the pesticide for the insects is improved, and generations of insect resistance is overcome and delayed.

Description

Technical field: [0001] The present invention relates to an insecticide composition, in particular to a new type of benzoylurea insect growth regulator, fluorine urea and abamectin, profenofos, lambda-cyhalothrin, methylamino group One or two or more synergistic compound compositions in abamectin. Background technique: [0002] Fluorourazone is a new type of benzoylurea insect growth regulator, which can prevent the synthesis of chitin during the molting stage of insect growth, thereby affecting insect molting and preventing pests from forming new epidermis during molting. It is deformed and dies. It can also regulate the growth and development of insects, inhibit molting and metamorphosis, and inhibit the eating speed of pests. It has high oviticidal activity. However, it has a poor quick effect and is ineffective against adults and eggs. [0003] Abamectin, profenofos, lambda-cyhalothrin, and methylamino abamectin are relatively new chemical pesticides, which can be widely used ...
