Embodiment 1

[0031] Example 1: 41% diafenthiuron·piflurid suspension concentrate (diafenthiuron:piflurid=40:1)

[0032]

[0033] The active ingredient, dispersant, wetting agent and water are uniformly mixed according to the formula ratio, and after grinding and high-speed shearing, a 41% diafenthiuron·pichridam suspension concentrate is obtained.

[0034] 25% diafenthiuron EC, 10% diafenthiuron SC and 41% diafenthiuron·pichridon SC were used for the control of tea tree green leafhopper. The control effects of 1 day after application were 76.34%, 70.22% and 85.47%, respectively; 7 days after application, the control effects of each agent were 85.24%, 78.73% and 96.84%, and 15 days after application, the control effects were respectively The ratios are 68.57%, 61.24% and 83.69%. The compounding of diafenthiuron and pichridam has obvious synergistic effect, and the control effect, quick effect and long-lasting effect on tea green leafhopper are obviously better than single agent.

Embodiment 2

[0037] Example 2: 20% diafenthiuron·pichridam emulsifiable concentrate (diafenthiuron:pichridam=1:1)

[0038]

[0039] The original drug containing active ingredients, emulsifier and co-solvent, etc. are sequentially added to the mixing tank according to the proportion of the formula, and stirred evenly to obtain 20% diafenthiuron·pichridam emulsifiable concentrate.

[0040] 25% diafenthiuron EC, 10% diafenthiuron SC, and 20% diafenthiuron·pichridon EC were used for the control of tea tree green leafhopper. The control effects of 1 day after application were 71.26%, 67.24% and 87.69%, respectively; 7 days after application, the control effects of each agent were 82.36%, 77.11% and 97.48%, and 15 days after application, the control effects were respectively The ratios are 69.33%, 66.78% and 85.42%. The synergistic effect of the combination of diafenthiuron and pichamiprid is obvious, and the control effect, quick effect and long-lasting effect on tea green leafhopper are obv...

Embodiment 3

[0044] Example 3: 30% diafenthiuron·pichridam water dispersible granules (diafenthiuron:pichridam=1:5)

[0045]

[0046] 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% diafenthiuron·pichridam water-dispersible granules were obtained.

[0047] 25% diafenthiuron emulsifiable concentrate, 10% diafenthiuron suspension concentrate, and 30% diafenthiuron·pichridon water dispersible granule were used to control tea leafhoppers. 1 day after spraying, the control effects were 79.54%, 72.51% and 89.12%, respectively; 7 days after spraying, the control effects of each agent were 84.23%, 78.51% and 98.63%, respectively; 15 days after spraying, the control effects were respectively The ratios were 72.14%, 68.86% and 87.74%. The synergistic e...

Abstract

The present invention discloses an insect disinfestation composition with a synergy effect. The insect disinfestation composition comprises effective components such as diafenthiuron and paichongding, wherein a mass ratio of the diafenthiuron to the paichongding is 40:1-1:50. The composition has a significant synergy effect, and can be provided for prevention and control of pests of tea trees and other crops, particularly for tea tree pest empoasca flavescens.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to a synergistic insecticidal composition containing diafenthiuron. Background technique [0002] Diafenthiuron (diafenthiuron) is a new type of thiourea high-efficiency insecticide and acaricide. It has contact killing, stomach poisoning, systemic and fumigation effects, and can control aphids, whiteflies, leafhoppers, etc. on various crops and ornamental plants. Pests and mites. The quick-acting agent is better, but the persistent effect is poor. [0003] Pichamid is a new type of high-efficiency, broad-spectrum, and low-toxicity neonicotinoid insecticide with a unique mode of action. It acts on the axonal synaptic receptors of insect nerve conduction, blocks nerve conduction, and exhibits a strong feeding inhibition effect. It has a strong systemic conduction effect, can be quickly absorbed by crops, and has a good control effect on rice planthoppers. Contents of the invention ...
