Abstract
The invention belongs to the field of pesticides, and discloses a composition for killing insects and mites. The composition comprises two active components, namely a component A and a component B; the active component A is pyriminostrobin, the active component B is selected from: organic chlorine pesticide, organic sulfur pesticide, organic tin pesticide, organic nitrogen pesticide, and organic phosphorus pesticide; and the weight ratio of the active component A to the active component B is 1:99 to 99:1. The composition has a prominent synergetic effect, and can be used to control insects and mites in multiple kinds of crops.
Description
technical field [0001] The invention belongs to the field of pesticides, and relates to an insecticidal and acaricidal composition containing two active components and its application. Background technique [0002] Reasonable mixing of insecticides and acaricides can achieve effects that cannot be obtained by using one agent alone, such as improving insecticidal and acaricidal effects, expanding the control spectrum, and extending the duration of efficacy, etc. However, the development of mixtures should follow a certain scientific basis, rather than arbitrary or groundless random use. [0003] The early agricultural acaricides used in the world are mainly inorganic compounds such as sulfur powder and its polysulfide compounds, and mineral oil (mainly engine oil) emulsions. In the 1950s, since the development of chlorfensulfone, which has only acaricidal effect, by the American Storfford Company, high-efficiency organic insecticides have appeared one after another, driving ...
