Embodiment 1

[0013] Example 1 Indoor Toxicity Determination of Plutella xylostella Plutella xylostella Compounded by Triflumepyrim and Tetrazolamid The test agents: trifluoropyrim original drug, tetrazolyn amide original drug (purchased on the market);

[0014] Insect source for testing: Plutella xylostella, collected in the field, and multi-generation breeding indoors; during the test, healthy third-instar larvae of the same size were selected for toxicity testing;

[0018]

[0019] Test method and data processing:

[0020] Use the leaf dipping method. Select fresh and normal leaves of Chinese cabbage, soak them in the medicinal solutions of each treatment mass concentration for 10 seconds, take them out, dry them, and put them in a petri dish with a diameter of 12 cm that is lined with wet filter paper. Instar diamondback moth larvae were used as test insects, and each ...

Embodiment 2

[0026] Example 2 Field control effect of trifluoropyrim and tetrapyrim compound on rice planthopper

[0027] Test method: During the test, the rice planthopper was in the blooming stage of young nymphs, and three species of brown planthopper, white-backed planthopper and brown planthopper were mixed, and brown planthopper was the dominant population. The experimental plots were arranged in random blocks, with an area of ​​40m2, spraying treatment, repeated 3 times. Before spraying, the field was irrigated with 5cm of water, and after spraying, a 3-5cm water layer was maintained for 5 days. The insect population base was investigated before spraying, and the control effect of pesticides was investigated 14 days after spraying. Each plot was sampled at 15 points by interlaced jumping method, and 2 clusters were surveyed at each point, a total of 30 clusters. , to calculate the control effect of each chemical treatment area:

Abstract

The invention provides a composition containing triflumezopyrim and tetraniliprole. The mass ratio of the triflumezopyrim to the tetraniliprole is (1:20)-(20:1). The composition is used for preventing and treating insect pests of crops. The composition is especially used for preventing and treating plutella xylostella, rice planthopper, leafhopper, rice leaf folder, chilo suppressalis and tryporyza incertulas.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a composition comprising trifluoropyrim and tetrapyrim and its application. Background technique [0002] The problem of pesticide resistance of agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical control of mite pests year after year, the increase in the use of pesticides, and the influence of factors such as unscientific use of pesticides, the resistance of pests is becoming more and more serious, and the types of pests that are resistant are increasing. At the same time, due to the high-intensity use of pesticides, a series of problems have been caused, such as excessive pesticide residues in agricultural products, aggravated environmental pollution, and increased pesticide costs for farmers, which is not conducive to the sustainable development of agriculture. ...
