Description

Insecticidal composition

the application is a divisional application with the application number of 201910553239.4, the application date of 2019, 6 months and 25 days and the name of an insecticidal composition.

Technical Field

The present invention relates to a pesticidal composition which is highly effective for controlling animal pests.

Background

The most typical problem in animal pest control is the need to reduce the dosage rate of the active ingredient to reduce or avoid adverse environmental or toxicological effects while still providing effective animal pest control effects.

Another difficulty with pest control is that repeated and unique use of a single pesticidal active ingredient in many cases results in a rapid selection of pests that produce natural or adaptive resistance to the active ingredient.

Due to the multiple generations and adaptation of the pests, the resistance of the pests is established in a relatively short time. There is also a need for pest control agents that have an effect on both pests and their larvae and eggs, which have superior penetration.

In addition, in pest control, there is also a need to combine knockdown activity with prolonged control time, i.e., rapid action and long-acting action.

The active ingredients of formula I are known from WO2006/129714 and belong to the Pyripropene derivatives.

Disclosure of Invention
