Problems solved by technology

[0004] The current pest control not only has poor control effect, but also uses different pesticides for different pests, which consumes a lot of manpower, material resources and financial resources, and also causes environmental pollution, and the continuous use of pesticides with a single active ingredient susceptible to drug resistance

Embodiment

[0050] The following examples will further illustrate the present invention, but do not limit the present invention thereby.

[0051] (1) Biological detection of synergistic effect

[0052] Sun Yunpei (Sun Y-P) method was used to evaluate the mixed effect of the two active ingredients in the insecticide composition of the present invention by calculating the co-toxicity coefficient (CTC), as follows:

[0053] Evaluation criteria: when CTC ≥ 120, it shows a synergistic effect; when CTC ≤ 80, it shows an antagonistic effect; 80 < CTC < 120, it shows an additive effect.

[0054] Calculation formula:

[0055] Co-toxicity coefficient (CTC) = [mixture actual toxicity index (ATI) / mixture theoretical toxicity index (TTI)] × 100

[0056] Mixture Actual Toxicity Index (ATI) = (LC of standard drug 50 / Mixed LC 50 )×100

[0057] Mixture theoretical toxicity index (TTI) = TI of agent A × content of A in the active ingredient of the mixture + TI of agent B × content of B in the activ...

Abstract

The invention relates to an insecticide composition which contains an active component and is characterized in that the active component contains indoxacarb and a carbamate insecticide, and a weight ratio of the indoxacarb to the carbamate insecticide is 1:(0.01-90). The invention also relates to an insecticide prepared with the insecticide composition, and an application of the insecticide in preventing and treating one or more injurious plant pests. The insecticide composition has a synergistic effect relative to the oligomict and the carbamate insecticide, can improve a prevention and treatment effect, is good in persistent effect, and contains the non-oligomict active component; the insecticide resistance is not generated easily; mixing generated various injurious insects in different types can be prevented and treated, so that the insecticide dosage can be lowered; the cost can be saved; and the pollution to an environment can be alleviated.

Description

technical field [0001] The present invention relates to a kind of insecticide composition and insecticide and application thereof, specifically, relate to a kind of insecticide composition containing indoxacarb and carbamate insecticide, and this insecticide composition The prepared insecticide and the application of the insecticide in controlling plant pests. Background technique [0002] In agricultural production practice, there are often problems of mixed occurrence of different types of pests. Lepidoptera, Homoptera, Coleoptera, Hymenoptera, Hemiptera, Thysanoptera pests and nematodes are pests that often exist simultaneously or successively. For example, on vegetables, tea trees, fruit trees, rice, cotton, corn, tobacco and ornamental plants. [0003] For the above-mentioned common pests, it is often necessary to use different insecticides for control. For example, rice planthoppers are generally controlled with pymetrozine or buprofezin, thrips are generally controll...
