The invention belongs to the technical field of the farm chemical, and in particular relates to a
plant insecticidal protective agent and an application thereof. The invention provides the
plant insecticidal protective agent which is recomposed by food suppressing hydrazine and
organic phosphorus (I), pyrethroids insecticides (ii),
insect growth regulation agent (III), Macrolides (IV), heterocyclic insecticidal component (V), carbamates (VI) or Nereistoxin
pesticide and the application thereof. The recomposed insecticidal composite remarkably improves the insecticidal effect, at least has four acting ways at the same time such as touch out,
stomach toxicity, internal absorption and antifeedant so as to adequately protect the
plant, favors the
delay of the production of the
drug resistanceof the insects through different acting ways, and enlarges the
pest control spectrum. The composite can be widely applicable to the control of different chewing mouthparts, piercing-sucking mouthparts, lapping mouthparts and rasping mouthparts pests.
