[0028] Example 1: 51% indoxacarb·pyridaben water dispersible granules (indoxacarb:pyridaben=50:1)

[0029]

[0030] 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, 51% indoxacarb·pyridaben water-dispersible granules were obtained.

[0031] 15% indoxacarb EC, 15% pyridaben EC, and 51% indoxacarb·pyridaben water-dispersible granules were used to prevent and control tea leafhoppers, and the control effects were 82.31% one day after application , 78.21% and 84.12%, 3 days after application, the control effects of each agent were 91.02%, 82.35% and 93.08%, and 7 days after application, the control effects of each agent were 87.14%, 75.32% and 90.34% , 12 days after application, the control effects were 82.62%, 68.54% and 85.34%, respectiv...

Embodiment 2

[0035] Example 2: 22% indoxacarb·pyridaben suspension concentrate (indoxacarb:pyridaben=10:1)

[0036]

[0037] The active ingredient, dispersant, wetting agent and water are uniformly mixed according to the ratio of the formula, and the 22% indoxacarb-pyridaben suspension is obtained after grinding and high-speed shearing.

[0038] 15% indoxacarb EC, 15% pyridaben EC, and 22% indoxacarb·pyridaben suspension were used to control tea leafhoppers, and the control effects were 85.16% and 75.42% one day after application. % and 90.16%, 3 days after application, the control effects of each agent were 90.28%, 80.21% and 95.81%, and 7 days after application, the control effects of each agent were 86.04%, 73.68% and 90.46%, respectively. 12 days after application, the control effects were 80.43%, 54.07% and 87.27%, respectively. The synergistic effect of compounding indoxacarb and pyridaben was obvious. All were significantly better than each single agent.

Abstract

The present invention relates to an indoxacarb-containing insect disinfestation composition, which comprises effective components such as indoxacarb and pyridaben, wherein a mass ratio of the indoxacarb to the pyridaben is 50:1-1:50. The composition can be processed into a water dispersible granule, a suspension, a water emulsion, an emulsifiable concentrate, a micro-emulsion, a microcapsule suspension or wettable powder, and can be provided for prevention and control of agricultural pests, particularly for tea tree pest empoasca flavescens.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing indida and its application. Background technique [0002] Leafhopper is a major pest that occurs widely in tea areas in my country and is highly harmful and should be controlled. Among them, Empoasca vitis Gothe is the most serious pest. At present, there have been relevant research reports on the control of green leafhoppers with a single dose of indoxacarb, but the duration of its control is relatively short, and the cost of use is high. In order to delay its drug resistance and prolong the service life of the drug, it is necessary Provided is a high-efficiency insecticidal composition suitable for controlling green leafhoppers. [0003] Indoxacarb (indoxacarb) is a new type of oxadiazine insecticide. Its mechanism of action is to irreversibly block the sodium ion channels in the nerve cells of pests, destroy the nerve impulse transmission o...
