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 stem borer with different ratios of epoxycloprid and monosultap

[0027] In order to confirm whether the mixture of epoxycloprid and monosultap has synergistic, additive or antagonistic effects, we first conducted a formula screening study on epoxycloprid and monosultap, and determined the indoor bioassay object It is the most serious damage to rice stem borer in my country. 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 monosultap to control rice stem borer is 45-54 grams of active ingredient / mu. Based on this, the experimental design formula The ratio is 1:1, 1:2, 1:5, 1:10, 1:20, 1:30, 1:40, 1:50, a total of 8 treatments, additionally set epoxyclocloprid, insecticidal single two single-dose treatment.

[0029] The experimental drugs used epoxycloprid original drug...

Embodiment 2

[0041] Example 2: Determination of co-toxicity coefficient of rice planthopper with different ratios of epoxycloprid and monosultap

[0042] In order to confirm whether the mixture of epoxycloprid and monosultap has a synergistic, additive or antagonistic effect on sucking mouthparts pests, we used the above 8 formulas of cyclocloprid and monosultap 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 soil with an appropriate amount of...

Abstract

The invention discloses an insecticidal composition containing cycolxylidin and monosultap. The composition contains the active ingredients of cycolxylidin and monosultap, and the mass ratio of cycolxylidin to monosultap is 1: (1 to 50). The insecticidal composition of the invention also has a synergistic effect on the basis of maintaining the original control effect; not only expands the insecticidal spectrum, but also delays the resistance of the pest to the drug. The insecticidal composition performs complex formulation of monosultap and a few of cycolxylidin, and the insecticidal effect thereof is obviously higher than that of the cycolxylidin or the monosultap by single application, the production cost is reduced, and the economic burden of the farmers can be mitigated.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition containing both active ingredients epoxycloprid and monosultap. 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] 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 ...
