Embodiment 1

[0108] Embodiment 1: Preparation of 20% thiamid fenvalerate suspension concentrate

[0109] Take by weighing 10% thiatiliprole, 10% fenvalerate, 10% emulsifier 1601# (styrene-based phenol polyoxyethylene polyoxypropylene ether), 3% acrylic acid homopolymer based on the total weight of the insecticide suspension sodium salt, 0.1% xanthan gum, 0.4% organosilicon defoamer, 3% glycerol and deionized water supplemented to 100%, according to the preparation method described in the specification of this application to prepare the suspension of the insecticide of the present invention agent.

[0110] The 20% thiatiliprole-fenvalerate suspension concentrate prepared in this example is used to control Plutella xylostella. The test method is as follows: at the peak stage of Plutella xylostella larvae, the 20% thiatiliprole-fenvalerate suspension concentrate prepared in this example was mixed with water and sprayed evenly at 20 g / mu.

[0111] The pesticide spraying test survey was carri...

Embodiment 2

[0114] Example 2: Preparation of 40% Thiamid Fenvalerate Water Dispersible Granules

[0115] Take by weighing 5% thiatiliprole, 35% fenvalerate, 3% sodium lauryl sulfate, 10% polycarboxylate, 5% ammonium sulfate, 15% polycarboxylate, 5% ammonium sulfate, 15% by weight of this insecticide water-dispersible granule gross weight. % white carbon black and kaolin supplemented to 100%, according to the preparation method described in the specification of this application, the insecticide water dispersible granule of the present invention is prepared.

[0116] The 40% thiatiliprole fenvalerate water-dispersible granules prepared in this example are used to control cabbage caterpillar. During the peak period of occurrence of cabbage caterpillar, the 40% thiabendamide-fenvalerate water-dispersible granule prepared in this example was uniformly sprayed with water at 10 g / mu.

[0117] The pesticide spraying test survey was carried out in accordance with the "Pesticide Field Efficacy Tes...

Embodiment 3

[0120] Embodiment 3: Preparation of 55% thiatiliprole fenvalerate wettable powder

[0121] Take by weighing 5% thiatiliprole, 50% fenvalerate, 3% sodium lauryl sulfate, 12% naphthalenesulfonic acid formaldehyde condensate sodium salt, 20% white carbon based on the total weight of the insecticide wettable powder Black and kaolin supplemented to 100% are prepared according to the preparation method described in the specification of this application to obtain the insecticide wettable powder of the present invention.

[0122] The 55% thiatiliprole-fenvalerate wettable powder prepared in this example is used to control corn borer. During the peak period of the occurrence of young corn borer larvae, the 50% thiamid-fenvalerate wettable powder prepared in this example was evenly sprayed with water at 8 g / mu.

[0123] The spraying test survey was carried out according to the "Pesticide Field Efficacy Test Guidelines (1) - Insecticide Control of Corn Borer" stipulated by the Institute...

Abstract

The invention relates to an insecticidal composition containing thiatiliprole and fenvalerate. The compounding of thiamid and fenvalerate according to the weight ratio of 1-30:1-60 has obvious synergistic effect. The insecticidal composition of the present invention is suitable for preventing and controlling insect pests such as beet armyworm, diamondback moth, cabbage caterpillar, peach borer, aphid or cotton bollworm, and at the same time preventing and controlling Lepidoptera, Homoptera, Orthoptera on vegetables and fruit trees. It also has good effects on pests such as orders and Hemiptera. The insecticidal composition of the present invention is better than a single dose in terms of quick-acting and persistent-acting properties, reduces the dosage and cost of pesticides, and is beneficial to environmental protection and comprehensive management of agricultural pests.

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 fenvalerate, 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 insectici...
