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 tolfenpyrad and fenvalerate. The tolfenpyrad and the fenvalerate are mixed at the weight ratio of (1-30) to (1-60) and have an obvious synergistic effect. The insecticidal composition provided by the invention is suitable for preventing and treating injurious insects including beet armyworms, diamondback moths, cabbage caterpillars, carposina niponensis walsingham, aphids or cotton bollworms and the like of crops; and meanwhile, the insecticidal composition also has good effects of preventing and treating injurious insects including lepidoptera, homoptera, orthoptera, hemiptera and the like on vegetables and fruit trees. Compared with a single dosage, the quick acting effect and the persistence of the insecticidal composition are better, and the utilization dosage and the drug cost of pesticides are reduced; and comprehensive management of environmental protection and agricultural destructive insects is 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 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...
