Technical Field

The invention belongs to the technical field of pesticides, and particularly relates to a pesticide composition of spearmint essential oil and bifenthrin.

Background

The plant essential oil is a volatile substance with characteristic odor extracted from natural plants, and mainly comprises terpenoids, aromatic compounds, aliphatic compounds and nitrogen-containing and sulfur-containing compounds. The plant essential oil has the characteristics of good insecticidal and bactericidal activity, strong specificity, easy degradation, low residue, difficult generation of drug resistance, environmental friendliness and the like, and is expected to be developed into a novel botanical insecticide. A large number of researches show that the plant essential oil has higher pesticide effect on pests, and the purpose of interfering the behavior of the insects is realized mainly by the modes of antifeedant, avoidance, fumigation, growth and development inhibition and the like.

Ectropis grissescens Warren is one of the most common and serious pests in Xinyang tea gardens in Henan province, and poses great threat to tea yield, quality and the like. At present, the prevention and control of the pests are mainly based on the prevention and control of chemical pesticides such as bifenthrin, deltamethrin, acetamiprid and the like to a great extent, and because of long-term improper use, the tea garden geometrid pests have higher resistance to partial insecticides. Moreover, the limit standard of pesticide residues in the tea is continuously updated at home and abroad, and the alternative pesticide application for preventing and controlling the ectropis griseus, which has less pesticide, high toxicity and low efficiency, has great influence on the production and export of the tea.

According to the invention, the spearmint plant essential oil is selected, the contact activity of the spearmint plant essential oil on the 2-instar larvae of the looper obliqua is researched, the synergistic effect of the spearmint plant essential oil on 98% bifenthrin insecticide is determined, and an important theoretical basis is provided for the application of the plant essential oil in pest control.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Disclosure of Invention

The invention aims to provide a pesticide composition of spearmint essential oil and bifenthrin, so as to overcome the defect that the control effect of the current medicament on the ectropis grisescens is poor due to different degrees of drug resistance of the current medicament.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:

the invention provides application of spearmint essential oil as a botanical pesticide.

The invention also provides a pesticide composition of the spearmint essential oil and the bifenthrin, and the effective components of the pesticide composition are compounded by the spearmint essential oil and the bifenthrin.

Preferably, the mass ratio of the spearmint essential oil to the bifenthrin is 1-10: 200.

preferably, the mass ratio of the spearmint essential oil to the bifenthrin is 1: 200.

preferably, the mass ratio of the spearmint essential oil to the bifenthrin is 10: 200.

compared with the prior art, the invention has the following beneficial effects:

the pesticide composition of the spearmint essential oil and the bifenthrin has no mutual resistance among the effective components, has good synergistic effect, can improve the control effect on the ectropis grisescens, reduce the pesticide application dosage, reduce the pesticide residue, relieve the environmental pressure, effectively delay the generation of the drug resistance of pests and reduce the control cost of the ectropis grisescens.
