Problems solved by technology

As we all know, the resistance of pests will cause the decline of agricultural product yield, the increase of agricultural production costs, the rampant pests and other hazards, and if the amount of pesticides is increased, it will also bring irreversible harm to the human living environment

Effect test

Embodiment 1

[0045] The inventors tested the indoor activity of the two-component insecticide composition.

[0046] Experimental effect calculation method:

[0047]

[0048]

[0049] The control effect was converted into a probability value (y), the concentration of the drug solution (μg / ml) was converted into a logarithmic value (x), and the toxicity equation and the inhibitory intermediate concentration EC50 (half maximum effect concentration) were calculated by the least square method.

[0050] Calculate the toxicity index and co-toxicity coefficient (CTC) of the drug by calculating the co-toxicity coefficient of the compound according to the toxicity index.

[0051]

[0052]

[0053]

[0054] Experimental judgment basis:

[0055] When CTC≤80, the composition exhibits antagonistic effect; when 80

[0056] Various compositions are obtained by mixing 4-p-phenoxyph...

Embodiment 2

[0060] The inventors tested the indoor activity of the two-component insecticide composition.

[0061] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0062] Various compositions are obtained by mixing 4-p-phenoxyphenoxymethyl-2-isopropyl-1,3-dioxolane and butylene fipronil at a weight ratio of 60:1 to 1:60, Several compositions corresponding to specific weight ratios were selected to determine its toxic effect on thrips, and the test results are shown in Table 2:

[0065]

Embodiment 3

[0067] The inventors tested the indoor activity of the two-component insecticide composition.

[0068] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0069] Various compositions are obtained by mixing 4-p-phenoxyphenoxymethyl-2-n-butyl-1,3-dioxolane and butylene fipronil at a weight ratio of 80:1 to 1:80, Several compositions corresponding to specific weight ratios were selected to measure its toxicity to psyllids, and the test results are shown in Table 3:

Abstract

The invention provides a double-component insecticide composition and application thereof to prevention and control of pests. The active component of the double-component insecticide composition is formed by compounding two components, namely a 1,3-dioxolane compound containing a 4-p-phenoxy phenoxy methyl structure (the compound as shown in a structural formula (I)) as well as any one of butene-fipronil, chlorfenapyr, indoxacarb and bifenazate; furthermore, through experiment detection, the medicine effect of the double-component insecticide composition is obviously higher than the preventioneffect of a single insecticide product / component, so that the dosage (the application total amount) of the composition is reduced, the disease-resistant risk of pests is effectively reduced, the useefficiency of the composition is improved and environmental pollution is obviously reduced. Therefore, the double-component insecticide composition has good market potential and wide application prospect in the aspect of preventing and controlling the pests.

Description

technical field [0001] The invention belongs to the technical field of insecticide compositions, and in particular relates to a two-component insecticide composition and its application in pest control. Background technique [0002] Pesticides and insecticides can be divided into: [0003] ①Nerve agent. Act on the nervous system of pests, such as DDT, parathion, carbofuran, pyrethrin, etc. [0004] ② Respiratory poison. The principle of this type of insecticide is to inhibit the respiratory enzymes of pests, such as hydrogen cyanide. [0005] ③Physical poisons. For example, mineral oil can block the pore of pests, and inert powder can wear out the epidermis of pests, causing the pests to die. [0006] ④ Specific pesticides. Causes abnormal physiological responses of pests, such as repellents that keep pests away from crops, inducers that attract pests with sex or bait, antifeedants that inhibit the taste of pests and stop eating so that they die of starvation, Sterili...
