Description
Technical field
The present invention relates to a kind of agricultural insecticidal composite and application thereof that contains pyrrole aphid ketone, contain pyrrole aphid ketone as first active component and any one Pesticidal combination and application thereof as second active component of being selected from gamma cyhalothrin, Nitenpyram, the chlopyrifos particularly a kind of comprising, belongs to technical field of compounded pesticide.
