[0042] 15% indoxacarb EC, 10% pichamprid suspension concentrate and 21% indoxacarb·pichamprid suspension concentrate were used for the control of tea tree green leafhopper. One day after spraying, the control effects were 78.52%, 71.57% and 82.45%, respectively; 7 days after spraying, the control effects of each chemical were 86.93%, 77.42% and 98.27%, and 15 days after spraying, the control effects were re...

Embodiment 2

[0046] Example 2: 20% indoxacarb·pichridam EC (indoxacarb:pichridam = 1:1)

[0047] Indoxacarb 10%

[0048] Picloprid 10%

[0049] Calcium dodecylbenzenesulfonate 3%

[0050] Octylphenol ethoxylate 4%

[0051] Dimethylsulfoxide 10%

[0052] Turpentine oil make up to 100%

[0053] Add the original drug containing active ingredients, emulsifier and co-solvent, etc. in sequence according to the formula ratio, and stir evenly to obtain 20% indoxacarb·pichonprid emulsifiable concentrate.

[0054] 15% indoxacarb EC, 10% pichamprid SC, and 20% indoxacarb·pichampudin EC were used for the control of tea leafhoppers. One day after spraying, the control effects were 73.58%, 68.12% and 89.99%, respectively; 7 days after spraying, the control effects of each chemical were 85.68%, 75.67% and 97.88%, and 15 days after spraying, the control effects were respectively 73.52%, 65.41% and 87.36%. The synergistic effect of compounding indoxacarb and pichridam was obvious, and the control effec...

Embodiment 3

[0058] Example 3: 30% indoxacarb·pichridam water dispersible granules (indoxacarb:pichridam = 1:5)

[0059] Indoxacarb 5%

[0060] Picloprid 25%

[0061] Sodium lignosulfonate 3%

[0062] PO-EO block polyether 1%

[0063] Sodium alkylbenzene sulfonate 2%

[0064] Urea 5%

[0065] Attapulgite up to 100%

[0066] The active ingredient, dispersant, wetting agent, disintegrating agent and filler are mixed evenly according to the ratio of the formula, crushed into a wettable powder by airflow, and then a certain amount of water is added to mix and extrude to make the material. After drying and sieving, 30% indoxacarb·pichonazole water dispersible granules were obtained.

[0067] 15% indoxacarb emulsifiable concentrate, 10% pichamprid suspension concentrate, and 30% indoxacarb·pichridam water dispersible granule were used for the control of tea leafhoppers. One day after spraying, the control effects were 78.66%, 72.51% and 88.86%, respectively. Seven days after spraying, the...

Abstract

The invention relates to an insecticidal composition. The effective components of the insecticidal composition are indoxacarb and Paichongding (C17H23ClN4O3), wherein the mass ratio of the indoxacarb to the Paichongding is (40:1)-(1:50). The invention also relates to an application of the insecticidal composition to control of tea lesser leafhoppers. The insecticidal composition has the advantages that after the indoxacarb and the Paichongding are compounded according to the proportion, the obvious synergistic action to pests is achieved, the drug resistance of the pests can be delayed or overcome, the drug amount used in field can be reduced, the environmental pollution and the pesticide residue are effectively reduced, the danger to beneficial organisms is reduced and the single-dose use cost of the indoxacarb can be reduced.

Description

technical field [0001] The invention belongs to the compound pesticide technology, and in particular relates to a synergistic insecticidal composition and its application. Background technique [0002] Indoxacarb (indoxacarb) is a new type of oxadiazine insecticide. Its insecticidal mechanism is to block the sodium ion channel in the nerve cells of the pests, so that the nerve cells of the pests are paralyzed and their coordination ability is reduced. eventually die. The medicament works by contacting or feeding into the insect body, and there is no cross-resistance with other insecticides. It can control Lepidoptera pests and leafhoppers on various crops and ornamental plants, and has high activity, and has good control effect on larvae of all ages. At the same time, it is very safe to natural enemy insects and has low residue in crops. It is an ideal agent for pest control in the production of pollution-free agricultural products. However, indoxacarb cannot be systemica...
