Problems solved by technology

[0011] Nereistoxins (VII) insecticides are a class of acetylcholine competitive inhibitors, which have strong contact, stomach poisoning and systemic conduction effects, and have a good control effect on the larvae of Lepidoptera pests. Insecticides have also been used for many years, with a single site of action and serious resistance

Abstract

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 resistance of 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.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a plant insecticide protection agent and its application. Background technique [0002] Hydrazine, chemical name: 2-benzoyl-1-tert-butylbenzohydrazide, chemical structural formula: [0003] [0004] The drug is a new type of insect growth regulator, mainly by reducing or inhibiting the feeding ability of larvae and adults, accelerating insect shedding, reducing egg laying, and hindering insect reproduction, so as to play an insecticidal role. It is mainly stomach poisonous to pests, and also has strong systemic absorption. It has a wide insecticidal spectrum and has a good control effect on Lepidoptera, Coleoptera, Diptera and other pests. The quick effect is poor, and it will take effect 48 hours after application. , with a longer duration. [0005] Organophosphorus (I) insecticides, the mechanism of action is mainly to inhibit the activity of acetylcholinest...
