Problems solved by technology

[0003] However, due to the rapid growth of imidacloprid resistance, with the accumulation of use 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, blocking the reproductive chain of plants in nature, and giving natural ecological diversity pose a serious threat
Therefore, whether imidacloprid can continue to be used has caused fierce debate in the agricultural management department and the pesticide production department.

Embodiment 1

[0020] Example 1: Determination of co-toxicity coefficient of rice stem borer with different ratios of pymetrozine and cartap

[0021] In order to confirm whether the mixture of pymetrozine and cartap has synergistic effect, additive effect or antagonistic effect, we first carried out formula screening research on pymetrozine and cartap, and set the object of indoor bioassay as The most serious damage to rice stem borer in my country's rice production, the specific measurement and results are as follows:

[0022] According to the data provided by the Pesticide Testing of the Ministry of Agriculture of China, the recommended dose of pymetrozine to control rice planthoppers is 5-10 grams of active ingredients / mu, and the recommended dose of cartap to control rice stem borer is 40-50 grams of active ingredients / mu. Mu, on the basis of this, the experimental design ratio was 1:1, 1:2, 1:5, 1:10, 1:20, 1:30, 1:40, 1:50, a total of 8 treatments, and the other Set up two single-dose ...

Embodiment 2

[0035] Example 2: Determination of the Co-toxicity Coefficient of Pymetrozine and Cartap to Rice Planthoppers in Different Proportions

[0036] In order to confirm whether the mixture of pymetrozine and cartap has synergistic, additive or antagonistic effects on sucking mouthparts pests, we used the above 8 formulas of pymetrozine and cartap to treat Rice planthoppers were tested for indoor toxicity. The 3rd instar adults of rice planthoppers were selected, and the determination method was dipping method.

[0037] 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 of water content (about 18%) and fresh paddy ...

Abstract

The invention discloses a pymetrozine and cartap -containing insecticidal composition. The composition contains the effective constituents such as pymetrozine and cartap, wherein the mass ratio of the pymetrozine to the cartap is 1: (1-50). The insecticidal composition enlarges the insecticidal spectrum on the basis of keeping the original prevention effect, can be used for delaying the drug resistance of the injurious insects and has a synergistic effect. The cost of the pymetrozine is higher than the cost of the cartap; according to the pymetrozine and monosultap-containing insecticidal composition, the cartap is compounded with a little pymetrozine, so that the insecticidal effect is remarkably higher than independent use of the pymetrozine or cartap, the production cost is reduced and the economic burden of the farmers is lightened.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition containing pymetrozine 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, pesticides compounded with imidacloprid and chlorpyrifos or triazophos, high chlorine, secbucarb, and isoprocarb 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 t...
