Problems solved by technology

However, when the two are used alone, there are advantages and disadvantages. For example, insecticidal sulfonate has a good effect on lepidopteran pests such as rice stem borer, rice stem borer, and rice leaf roller, and has a poor effect on rice planthoppers and other piercing-sucking mouthpart pests. , and trifluoropyrimidine showed excellent control effect on piercing-sucking mouthparts pests such as rice planthopper, but basically ineffective against Lepidoptera pests

Embodiment 1

[0024] Example 1: Determination of co-toxicity coefficient of rice stem borer with different ratios of trifluoropyrimidine and insecticide

[0025] In order to confirm whether the mixture of trifluoropyrimidine and sulfonic acid has synergistic effect, additive effect or antagonistic effect, we first conducted a formula screening study on trifluoropyrim and sulfonic acid, and determined the object of indoor bioassay. It is the most serious damage to rice stem borer in my country. The specific measurement and results are as follows:

[0026] According to data reports, the recommended dose of trifluoropyrimidine for the control of rice planthoppers is 1-1.5 grams of active ingredient / mu, and the recommended dose of insecticide for the control of rice stem borer is 40 grams of active ingredient / mu. Based on this, the test The design ratio is 1:1, 1:2, 1:5, 1:10, 1:20, 1:30, 1:40, 1:50, 1:60, 1:70, 1:80, 1: 90, 1:100, a total of 13 treatments, and two single-dose treatments of tri...

Embodiment 2

[0040] Example 2: Determination of co-toxicity coefficient of different ratios of trifluoropyrimidine and insecticide to rice planthopper

[0041] In order to confirm whether the mixture of trifluoropyrimidine and insecticide has synergistic effect, additive effect or antagonistic effect on sucking mouthparts pests, we used the above 13 formulations of trifluoropyrim and insecticide mixture, Indoor virulence assays were carried out on rice planthoppers. The 3rd instar nymphs of rice planthoppers were selected, and the determination method was dipping method.

[0042] Put the test insects into the funnel folded with filter paper, take 3mL of the above liquid medicine into the funnel with a pipette gun, keep the test insects in the liquid medicine for 30 seconds, take them out and put them on the filter paper to absorb the excess liquid medicine , the test insects were transferred to glass insect culture tubes (diameter 1.8cm, height 8cm) and put into wet soil with an appropria...

Embodiment 3

[0051] Example 3: 50% trifluoropyrim · insecticide wettable powder

[0052]

[0053] The above active ingredients trifluoropyrim, insecticide and various pesticide auxiliaries are processed according to the conventional processing method of pesticide wettable powder to obtain 50% trifluoropyrim · insecticide wettable powder.

Abstract

The invention discloses an insecticidal composition comprising triflumezopyrim and bensultap. The composition includes the triflumezopyrim and bensultap as active components according to the mass ratio of 1:1-100. The insecticidal composition, on the basis of original prevention effects, not only is enlarged in insecticidal spectrum but also can delay drug resistance of pests to the pesticides and has synergistic effect. The price of the triflumezopyrim is far higher than that of the bensultap, so that by compounding the bensultap with a less amount of the triflumezopyrim, the composition is significantly higher than single triflumezopyrim or bensultap in insecticidal effect. In addition, production cost is reduced and economic burden of farmers is reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition containing trifluoropyrimidine and insecticidal sulfonate. Background technique [0002] In recent years, the scientific compounding of two or more insecticides to expand the insecticidal spectrum or improve the control effect has been widely used. Compounded pesticides such as emamectin benzoate and monosultap, imidacloprid and monosultap, chlorpyrifos and dimehypo, methomyl and dimehypo have been used in agricultural production. [0003] Rice is the main grain crop in my country. Rice borers and planthoppers are the main pests in rice planting, among which the rice borer, brown planthopper and white-backed planthopper are the most harmful. [0004] Chilo suppressalis (Walker) is one of the most serious and frequent pests of rice in my country. It is damaged at the tillering stage and causes dead sheaths and seedlings. It is damaged at the heading stage and...
