Problems solved by technology

However, when the two are used alone, they have their own advantages and disadvantages. For example, cartap 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. , while trifluoropyrimidine showed excellent control effect on piercing-sucking mouthparts such as rice planthopper, but basically ineffective against lepidopteran pests

Embodiment 1

[0025] Example 1: Determination of the co-toxicity coefficient of trifluoropyrimidine and cartap to rice stem borer in different ratios

[0026] In order to confirm whether the mixture of trifluoropyrim and cartap has synergistic effect, additive effect or antagonistic effect, we first conducted a formula screening study on trifluoropyrim and cartap, 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:

[0027] According to the data provided by the Pesticide Testing of the Ministry of Agriculture of China, the recommended dose of trifluoropyrim to control rice planthopper is 1-1.5 grams of active ingredient / mu, and the recommended dose of cartap to control rice stem borer is 45-54 grams of active ingredient / mu, based on this, the experimental 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...

Embodiment 2

[0040] Example 2: Determination of the co-toxicity coefficient of trifluoropyrimidine and cartap to rice planthoppers in different ratios

[0041] In order to confirm whether the mixture of trifluoropyrimidine and cartap has synergistic effect, additive effect or antagonistic effect on sucking mouthparts pests, we used the above 13 formulations of trifluoropyrim and cartap 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 are transferred to glass insect culture tubes (diameter 1.8cm, height 8cm) and put into wet soil with an appropriate amount o...

Embodiment 3

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

[0052]

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

Abstract

The invention discloses insecticidal composition containing triflumezopyrim and cartap. The composition contains active ingredients triflumezopyrim and cartap, wherein the mass ratio of triflumezopyrim to cartap is 5-90. According to the insecticidal composition, on the basis that the original control effect is kept, the insecticidal spectrum is expanded, drug resistance of pests can be delayed, and the insecticidal composition further has a synergistic effect. The cost of triflumezopyrim is far higher than that of cartap, by compounding cartap with a small amount of triflumezopyrim, the insecticidal effect is obviously higher than that of single used triflumezopyrim or cartap, the production cost is reduced, and financial burden of farmers is relieved.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition containing trifluoropyrim and cartap. 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 causes insect damage...
