Problems solved by technology

Young and tender fruits (such as peppers, eggplants, cucumbers, watermelons, etc.) will harden after being damaged, and the fruit will be deformed, with rough skin and spots covered with "rust skin". In severe cases, it will cause fruit drop, which will seriously affect the yield and quality
[0003] When crops are infested with insects, multiple pests often occur at the same time. Insecticides used alone have a limited range of control and cannot provide comprehensive protection for crops, and pests are prone to resistance

Embodiment 1

[0033] Embodiment 1: pest control effect test

[0034] The insecticidal composition uses dinotefuran and cyantraniliprole as active ingredients, and the single doses are respectively dinotefuran and cyantraniliprole. The test objects are flea beetle, diamondback moth, aphids and thrips. The number of each pest is counted before the test. Statistical results 7 days after the drug, the test environment is the same, the drug effect is calculated according to the following formula:

[0035] Insect population reduction rate = [(number of live insects before treatment - number of live insects after treatment) ÷ number of live insects before treatment] × 100%

[0036] Control effect = [(Insect population reduction rate in the application area - Insect population reduction rate in the control area) ÷ (1 - Insect population reduction rate in the control area)] × 100%

[0037] See Table 1 for test treatments and application rates, and Table 2 for control effects.

Embodiment 2

[0043] Example 2: 20% dinotefuran · cyantraniliprole EC

[0044] Dinotefuran 2%, cyantraniliprole 8%, Nongru 500# 2%, OP 10%, solvent oil No. 100 make up 100%, and after fully mixing and dissolving, 20% dinotefuran·cyantraniliprole EC is obtained.

Embodiment 3

[0045] Example 3: 30% dinotefuran · cyantraniliprole suspension concentrate

[0046] Dinotefuran 5%, cyantraniliprole 25%, sodium dodecyl sulfonate 6%, sodium lignosulfonate 5%, xanthan gum 3%, silicone 0.5%, water supplement 100%, fully mixed and ground , that is, to obtain 30% dinotefuran · cyantraniliprole suspension concentrate.

Abstract

The invention relates to the field of pesticide preparations and discloses an insecticide composition and a preparation of the insecticide composition. The insecticide composition consists of dinotefuran and cyantraniliprole according to a weight ratio of 1:(1-6). The invention also discloses the preparation of the insecticide composition, which consists of the insecticide composition provided by the invention and pesticide preparation acceptable auxiliary materials, and the insecticide composition accounts for 1 to 90 weight percent of the insecticide. The insecticide composition and the preparation of the insecticide composition have the advantages that the insect killing effect is obviously improved, in addition, homoptera, thysanoptera, lepidoptera and coleopteran pests can be simultaneously prevented and treated, in addition, a special effect is realized on piercing-sucking mouthpart pests, meanwhile, the pest drug resistance is retarded, the drug application cost is greatly reduced, in addition, higher safety on people, livestock and environment can be realized, and the insecticide composition and the preparation of the insecticide composition can be widely applied to various crops of rice, cotton, vegetables, fruit trees and the like.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to an insecticidal composition and its preparation. Background technique [0002] Pests with piercing-sucking mouthparts, such as aphids, thrips, whiteflies, spider mites, and scales, are difficult to control because of their small size and rapid reproduction, but these pests occur frequently. Thrips are insects that suck plant sap, and are pests of the order Thysanoptera. Larvae are white, yellow, or orange, and adults are brown or black. Thrips are highly mobile with adults and nymphs, and have strong fecundity, which can occur throughout the year. In spring, summer and autumn, the damage mainly occurs on field crops, and in winter, it mainly damages greenhouse crops. Adults and nymphs of thrips can file and suck the juice of young plant tissues (twigs, leaves, flowers, fruits, etc.), and like to inhabit the overlapping places of petals and sepals, feed on the edges of pet...
