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. , and cyantraniliprole not only has a certain control effect on lepidopteran pests such as rice borer, but also shows excellent control effect on piercing-sucking mouthparts pests such as rice planthopper and brown planthopper

Embodiment 1

[0017] Example 1: Determination of co-toxicity coefficient of rice stem borer with different ratios of cyantraniliprole and cartap

[0018] In order to confirm whether the mixture of cyantraniliprole and cartap has synergistic effect, additive effect or antagonistic effect, we first carried out formula screening research on cyantraniliprole and cartap, and determined the objects of indoor bioassay. It is the most serious damage to rice stem borer in my country. The specific measurement and results are as follows:

[0019] According to the data provided by the Ministry of Agriculture of China, the recommended dose of cyantraniliprole for the control of rice planthoppers is 5-6 grams of active ingredients per mu, and the recommended dose of cartap for the control of rice stem borer is 40-50 grams of active ingredients / mu, based on this, the test design ratio was 1:1, 1:2, 1:5, 1:10, 1:20, 1:30, 1:40, 1:50, 1:60, a total of 9 two single-dose treatments of cyantraniliprole and c...

Embodiment 2

[0033] Example 2: Determination of the co-toxicity coefficient of rice planthoppers with different ratios of cyantraniliprole and cartap

[0034] In order to confirm whether the mixture of cyantraniliprole and cartap has synergistic effect, additive effect or antagonistic effect on sucking mouthparts pests, we also used the above cyantraniliprole and cartap alone and their mixture The 9 formulations of the rice planthopper were tested for indoor toxicity to rice planthoppers. The 3rd instar nymphs of rice planthoppers were selected, and the determination method was dipping method.

[0035] 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 ...

Embodiment 3

[0044] Example 3: 50% cyantraniliprole · cartap wettable powder

Abstract

The invention discloses an insecticidal composition containing cyantraniliprole and cartap. The composition contains the active ingredients cyantraniliprole and cartap, wherein the mass ratio of cyantraniliprole to cartap is 1:(1-60). On the basis that the original control effect is maintained, the insecticidal composition broadens the insecticidal spectrum, can delay generation of the insecticide resistance of injurious insects and also has the synergistic effect. The price of cyantraniliprole is higher than that of cartap, and cartap is compounded with a small amount of cyantraniliprole, so that the insecticidal effect of the insecticidal composition is obviously better than that of an insecticide only containing cyantraniliprole or cartap, the production cost is reduced, and the economical burden of farmers is relieved.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition containing both cyantraniliprole 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. For example, compound pesticides such as imidacloprid and cartap have been widely used in agricultural production. [0003] However, due to the rapid growth of imidacloprid resistance, with the accumulation of application time, the control effect continues to decline, and the dosage per mu increases significantly, which not only increases the cost of agricultural production, but also increases the impact on the environment. [0004] In particular, imidacloprid not only has high resistance, but also seriously poisons the bee colonies that spread pollen in nature, thus reducing the bee colony in nature to spread plant pollen, blo...
