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

Effect test

Embodiment 1

[0033] Embodiment 1: pest control effect test

[0034] The insecticidal composition uses thiamethoxam and cyantraniliprole as active ingredients, and the single doses are thiamethoxam and cyantraniliprole respectively. Flea beetles, diamondback moths, aphids and thrips are used as test objects, and 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

[0044] Embodiment 2: 25% thiamethoxam · cyantraniliprole suspension concentrate

[0045] Thiamethoxam 5%, cyantraniliprole 20%, sodium dodecyl sulfonate 3%, sodium lignosulfonate 7%, sucrose 3%, silicone 0.3%, water supplement 100%, after fully mixing and grinding, that is Obtain 25% thiamethoxam · cyantraniliprole suspension concentrate.

Embodiment 3

[0046] Embodiment 3: 30% thiamethoxam · cyantraniliprole suspension concentrate

[0047] Thiamethoxam 10%, cyantraniliprole 20%, fatty alcohol polyvinyl ether 6%, sodium lignosulfonate 5%, starch 3%, silicone 0.5%, water supplement 100%, after fully mixing and grinding, 30 % Thiamethoxam·cyantraniliprole suspension concentrate.

Abstract

The invention relates to the field of pesticide preparations and discloses an insecticidal composition and a preparation thereof. The insecticidal composition comprises thiamethoxam and chlorantraniliprole, wherein a weight ratio of the thiamethoxam to the chlorantraniliprole is 1:0.2-4. The invention also discloses the preparation of the insecticidal composition; the preparation is composed of the insecticidal composition and an auxiliary material acceptable in a pesticide preparation; and the insecticidal composition accounts for 1%-90% of an insecticide in percentage by weight. The insecticidal composition and preparation provided by the invention have the advantages of obviously increasing the insecticidal effects, being capable of simultaneously controlling homoptera, thysanoptera, lepidoptera and coleopteran pests, having the specially good effect on piercing-sucking mouthpart pests, simultaneously reducing the insecticide resistance of the pests, substantially reducing the pesticide using cost, having very high safety on people, livestock and environments and can be widely applied to multiple crops such as 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...
