Problems solved by technology

[0009] However, due to the rapid growth of resistance to neonicotinoid pesticides such as imidacloprid and acetamiprid, the control effect continues to decline with the accumulation of use time, and the dosage per mu increases significantly, which not only increases the cost of insect control, but also increases the impact on the environment. influences
[0010] In particular, imidacloprid and acetamiprid not only have high 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

[0025] Example 1: Determination of co-toxicity coefficient of flurpirfurone and insecticide in different ratios to rice leaf roller

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

[0027] According to data reports, the recommended dose of flurpirfurone to control rice planthoppers is 5-6 grams of active ingredients / mu, and the recommended dose of insecticide to control rice leaf rollers is 40 grams of active ingredients / 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, a total of 9 treatments, and fluorine Two single-dose treatments of pyfuranone and insecticide.

[0028] The test drugs used the original drug of flur...

Embodiment 2

[0041] Example 2: Determination of the co-toxicity coefficient of flurpirfurone and insecticide in different ratios to rice planthoppers

[0042] In order to confirm whether the mixture of flurpirfuranone and sulphon has a synergistic effect, an additive effect or an antagonistic effect on sucking mouthparts pests, we used the above 9 formulas of flurpirfuranone and sulphon , the indoor virulence assay of rice planthopper was carried out. The 3rd instar nymphs of rice planthoppers 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 wat...

Abstract

The invention discloses an insecticidal composition containing flupyradifurone and bensultap. The composition includes active ingredients, namely flupyradifurone and bensultap, wherein the mass ratio of flupyradifurone to bensultap is1:(1-60). The insecticidal composition has the synergistic effect on the basis of maintaining the original control effect, expands the insecticidal spectrum and meanwhile delays the generation of resistance of pests to the pesticide. The price of flupirfurone is much higher than that of bensultap, bensultap is made to be compounded with a small amount of flupyradifurone, the insecticidal effect of the insecticidal composition containing flupyradifurone and bensultap is much higher than that of single use of flupirfurone or bensultap, the production cost is also reduced and the economic burden of farmers is relieved.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition containing both active ingredients flurpirfurone and insecticidal sulfon. 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 rice 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 i...
