Description

Insecticidal composition

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

Technical Field

The present invention relates to an insecticidal composition which is highly effective against 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 in pest control is that the repeated and exclusive use of a single pesticidal active ingredient results in rapid selection of pests that either naturally develop or are adapted to resistance to the active ingredient in many cases.

Due to the multi-generation and adaptability of pests, the resistance of pests is formed in a rather short time. There is also a need for a pest control agent having an effect on both pests and their larvae and eggs, which has 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-lasting action.

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