Problems solved by technology

[0005] Thiantamid and beta-cypermethrin are costly when used alone, which limits their popularization and application to a certain extent, and long-term single use is likely to increase the degree of pest resistance
[0006] There are still some technical defects in these existing technologies, which cannot meet the needs of current agricultural production. Therefore, it is necessary to develop new insecticidal compositions, which is of great significance for promoting the development of large-scale agriculture.

Embodiment 1

[0106] Embodiment 1: Preparation of 20% thiatilicon · beta-cypermethrin suspension concentrate

[0107] Take by weighing 10% thiatiliprole, 10% beta-cypermethrin, 10% emulsifier 1601# (styrene-based phenol polyoxyethylene polyoxypropylene ether), 3% acrylic acid homopolymer sodium Salt, 0.12% xanthan gum, 0.4% organosilicon defoamer, 3% glycerin and deionized water supplemented to 100%, are prepared according to the preparation method described in the specification of the present invention to obtain the insecticide suspension of the present invention.

[0108] The 20% thiatiliprole·beta-cypermethrin suspension concentrate prepared in this example is used to control Plutella xylostella. The test method is as follows: the 20% thiatiliprole·beta-cypermethrin suspension concentrate prepared in this example was mixed with water and sprayed evenly at 10 g / mu at the peak occurrence stage of Plutella xylostella larvae.

Embodiment 2

[0112] Embodiment 2: Preparation of 40% thiatiliprole·beta-cypermethrin water dispersible granules

[0113] Take by weighing 5% thiatiliprole, 35% beta-cypermethrin, 3% sodium lauryl sulfate, 10% polycarboxylate, 5% ammonium sulfate, 5% white Carbon black and kaolin supplemented to 100% are prepared according to the preparation method described in the specification of this application to obtain the insecticide water-dispersible granule of the present invention.

[0114] The 40% thiatiliprole·beta-cypermethrin water-dispersible granule prepared in this example is used to control Spodoptera litura. During the peak period of Spodoptera litura occurrence, the 40% thiatiliprole·beta-cypermethrin water-dispersible granule prepared in this example was uniformly sprayed with water at 5 g / mu.

Abstract

The invention relates to an insecticide composition containing thiotraniliprole and beta-cypermethrin. The thiotraniliprole and beta-cypermethrin are blended in a weight ratio of (1-30):(1-60) to realize a remarkable synergistic effect. The insecticide composition is suitable for preventing and controlling the pests such as plutella xylostella, pieris rapae, prodenia litura, helicoverpa armigera, ostrinia nubilalis, homona magnanima and phyllocnistis citrella of crops. The insecticide composition is superior to single dosage in fast-acting property and persistence, the pesticide dosage and cost are reduced, and environmental protection and comprehensive treatment of agricultural pests are facilitated.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides. More specifically, the present invention relates to an insecticidal composition containing thiatiliprole and beta-cypermethrin, and also relates to the use of the insecticidal composition. 【Background technique】 [0002] In the practice of agricultural production, we often face the phenomenon of mixed occurrence of multiple pests on one crop. For example, when rice plants are damaged by rice planthoppers, they are often accompanied by mixed damage from rice leaf rollers, rice stem borers, and rice stem borers. Whiteflies, aphids and diamondback moths, Spodoptera litura, and Beet Spodoptera often occur mixedly. For this reason, people often will repeatedly apply pesticides and just can reach control multiple pest. Therefore, there is an urgent need in production for pesticide products that can control multiple pests at one time, so as to reduce agricultural costs. [0003] Thiamidamide ins...
