Problems solved by technology

[0009] However, due to the rapid growth of resistance to neonicotinoid pesticides such as imidacloprid, thiamethoxam, acetamiprid, etc., 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 pest control, but also increased impact on the environment
[0010] In particular, imidacloprid and thiamethoxam not only have high drug resistance, but also seriously poison 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 Serious threats to natural biodiversity
Therefore, whether imidacloprid can continue to be used has caused fierce debate in the agricultural management department and the pesticide management department.

Embodiment 1

[0026] Example 1: Determination of co-toxicity coefficient of rice leaf roller in different ratios of epoxycloprid and insecticidal ring

[0027] In order to confirm whether the mixture of epoxycloprid and insecticidal ring has synergistic, additive or antagonistic effects, we first conducted a formula screening study on epoxycloprid and insecticidal ring, and determined the indoor bioassay object It is the rice leaf roller which is the most harmful in my country's rice production. The specific measurement and results are as follows:

[0028] The recommended dose of epoxycloprid to control rice planthopper is 2-3 grams of active ingredient / mu, and the recommended dose of insecticidal ring to control rice leaf roller is 45-54 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, a total of 8 treatments, and epoxyclocloprid, insecticidal Ring two single-dose treatments.

[0029] The original drug of epoxycloprid ...

Embodiment 2

[0041] Example 2: Determination of co-toxicity coefficient of rice planthoppers with different ratios of epoxycloprid and insecticidal ring

[0042] In order to confirm whether the mixture of epoxycloprid and insecticidal ring has synergistic effect, additive effect or antagonistic effect on sucking mouthparts pests, we used the above 8 formulas of epoxycloprid and insecticidal ring mixed and two single doses, the indoor toxicity test of rice planthopper was carried out. The 3rd instar nymphs of rice brown planthopper were selected, and the determination method was dipping method.

[0043] 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 ...

Abstract

The invention discloses an insecticidal composition containing epoxy thiacloprid and thiocyclam. The composition contains the active components of epoxy thiacloprid and thiocyclam, wherein the mass ratio of the epoxy thiacloprid to the thiocyclam is 1 to (1 to 50). The insecticidal composition provided by the invention has a synergistic effect on the basis of keeping original prevention and control effect; moreover, the insecticidal spectrum is enlarged, and the drug resistance of pests to drugs can be delayed. The epoxy thiacloprid is greatly higher than the thiocyclam in price. After the thiocyclam is compounded with a small amount of epoxy thiacloprid, the insecticidal effect of the mixture is remarkably better than that of the epoxy thiacloprid or the thiocyclam used separately, the production cost is lowered, and the economic burden of peasants is lowered.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition containing both active ingredients epoxycloprid and insecticidal ring. 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. Such as abamectin and monosultap, imidacloprid and monosultap, chlorpyrifos and monosultap, buprofezin and monosultap and other compound pesticides have been applied in agricultural production. [0003] Rice is the main food crop in my country. Rice borers and planthoppers are the main pests in rice planting, among which rice leaf rollers, rice stem borers, brown planthoppers and white-backed planthoppers are the most harmful. [0004] The rice leaf roller (Cnaphalocrocis medinalis Guenee) is one of the main pests in rice producing areas in my country, and it is widely distributed in variou...
