Embodiment 1

[0030] Embodiment 1: Insect pest control effect test

[0031] The insecticidal composition uses cyantraniliprole and nitenpyram as the active ingredients, and the single doses are cyantraniliprole and nitenpyram respectively. Aphids, planthoppers, fruit flies and weevils are used as test objects, and each pest is counted before the test. The quantity, statistical results 7 days after the drug, and the test environment are all the same, and the drug effect is calculated according to the following formula:

[0032] Insect population reduction rate = [(the number of live insects before the drug - the amount of live insects after the drug) ÷ the amount of live insects before the drug] × 100%

[0033] Control effect = [(reduction rate of insect population in spraying area-reduction rate of insect population in control area)÷(1-reduction rate of insect population in control area)]×100%

[0034]See Table 1 for test treatments and application rates, and Table 2 for control effects. ...

Embodiment 2

[0044] Example 2: 35% cyantraniliprole · nitenpyram wettable powder

[0045] Cytraniliprole 5%, Nitenpyram 30%, Sodium Lauryl Sulfate 6%, Sodium Lignosulfonate 7%, Kaolin to make up to 100%, fully mixed, after crushing, 35% Cytraniliprole is obtained Nitenpyram wettable powder.

[0046] The insecticide prepared in this embodiment is compared with the single agent made from a single active ingredient, and the amount of each active ingredient in the insecticide according to the present invention is less than the amount of each single agent active ingredient. Under the premise of the above, the control effect of the insecticide described in the present invention is higher than that of a single agent, and has no cross resistance, and the control effect on chewing mouthparts pests of Lepidoptera and Coleoptera is enhanced.

Embodiment 3

[0047] Example 3: 40% cyantraniliprole · nitenpyram water dispersible granules

[0048] 20% cyantraniliprole, 20% nitenpyram, 7% alkylnaphthalene formaldehyde condensate, 7% alkylamino taurate, 2% urea, 0.3% xanthan gum, and kaolin to 100%. Thoroughly mix and dissolve to obtain 40% cyantraniliprole-nitenpyram water-dispersible granules.

[0049] The insecticide prepared in this embodiment is compared with the single agent made from a single active ingredient, and the amount of each active ingredient in the insecticide according to the present invention is less than the amount of each single agent active ingredient. Under the premise of the above, the control effect of the insecticide described in the present invention is higher than that of a single agent, and has no cross resistance, and the control effect on chewing mouthparts pests of Lepidoptera and Coleoptera is enhanced.

Abstract

The invention discloses an insecticidal composition and preparation and application thereof. The insecticidal composition is made of cyantraniliprole and nitenpyram in a weight ratio of 1:0.1-10. The insecticidal composition is made of pesticide preparation acceptable auxiliaries. The insecticidal composition accounts for 1%-80% of insecticide. The insecticidal effect of the insecticide is evidently improved, the insecticide can be used for controlling lepidopteran pests, hemiptera pests, colopteran pests, homopterous pests and part of thysanoptera pests, generation of drug resistance of the pests is retarded, cost in drug use is lowered greatly, the insecticide is highly safe for human, livestock and environment and is widely applicable to wheat, 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 and application. Background technique [0002] Piercing-sucking pests, also known as the "five small" pests, are five types of pests, namely aphids, scale insects, spider mites, whiteflies, and thrips. They all penetrate the leaves, tender stems, leaf sheaths, and flower buds of plants through their mouthparts. , calyx, fruit, root, tuber, etc., absorb cell juice, destroy leaf stomata, spongy tissue and palisade tissue, and secrete toxic and harmful substances, hindering the normal growth and development of plants, resulting in the following main disease symptoms: Leaf chlorosis , yellowing, redness, scorch or formation of galls; diseased buds are deformed; leaves and peels are rusty; leaves become felt; cause fruit cracking. In severe cases, the leaves, flowers, and fruits of plants will fall, and even a large area of ​​plant...
