Tolfenpxrad-containing smoke agent

Abstract

The invention discloses a tolfenpxrad-containing smoke agent, which contains an active component, an auxiliary agent, a solvent and a cosolvent. The invention is characterized in that tolfenpxrad is used as an active component, or tolfenpxrad and an active component B are compounded to form an active component, and the auxiliary agent, the solvent and the cosolvent are added into the active component to obtain the smoke agent. The active component B is any one selected from the group consisting of avermectin, emamectin benzoate (emamectin benzoate chlorfenapyr), acetamiprid, imidacloprid, nitenpyram, thiamethoxam, thiacloprid and beta-cypermethrin. The invention relates to a pesticide which has a long persistent period and is rainwash resistant. With the combination of the smoke agent, the pesticide is used to control sugarcane aphid, banana tortrix, Basilepta fulvipes and the like, is simultaneously suitable for big trees and facility agriculture, and has characteristics of labor and drug conservation, pollution reduction, no water source limitation and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an aerosol containing tofenpyrad. Background technique [0002] Aerosol means that the original pesticide is dissolved in a solvent with an appropriate flash point and viscosity, and then other additives are added to prepare a preparation of a certain specification, and the preparation is quantitatively mixed with a high-temperature and high-speed hot air flow into the atmosphere by means of a fog machine. Forms micron-sized mist or smoke. Aerosols have the following properties: [0003] 1. The mist droplets are extremely fine, evenly dispersed, and have good permeability, which improves the deposition of pesticides on target crops. [0004] 2. The dosage is less, which reduces the pollution of pesticides to the environment. [0005] 3. Long duration, strong adhesion to the target and strong resistance to rain erosion. [0006] 4. High efficiency, no need to add water, sui...

AI Technical Summary

Problems solved by technology

[0020] At present, the commercially available preparations are mainly emulsifiable concentrates, and there is no aerosol agent of tofenpyrad.

Secondly, the active ingredient (B) abamectin, abamectin benzoate, acetamiprid, imidacloprid, nitenpyram, thiamethoxam, thiacloprid, and beta-cypermethrin are commonly available in the market as emulsifiable concentrate, suspension Agents, microemulsions, wettable powders, and water-dispersible granules. The long-term single and large-scale use of such active ingredients makes pests develop strong resistance, which is not conducive to the further improvement of drug efficacy and increases the difficulty of pest control. Increasing the amount of medicine and the frequency of spraying will not only increase the labor intensity but also increase the cost of prevention and control

In addition, the large-scale use of pharmaceuticals will inevitably lead to an increase in the amount of residues in the environment
