Ultra-low volume liquid agent containing hexaflumuron

Abstract

An ultra-low volume liquid agent containing hexaflumuron of the invention takes hexaflumuron, or hexaflumuron and active component B as active ingredient, the active ingredient is 0.1% to 30% and the rest is auxiliary agent and solvent to make 100% ultra-low volume liquid agent. The active component B is any one of bifenthrin, ethofenprox, cyfluthrin, diazinon, abamectin, emamectin benzoate, pleocidin, spinetoram, spirotetramat and ethiprole. The invention has simple and convenient production, high working efficiency, less water amount, long effective period, uneasy drug resistance of target, low environment pollution and strong synergism. Insects to wheat, corn, vegetables, tobacco, tea plant, fruit plant, cotton, wood and sugarcane can be prevented by ultra-low volume spray, low volume spray and low volume static electric spray.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an ultra-low volume liquid containing hexaflumuron. Background technique [0002] Hexaflumuron, molecular formula: C 16 h 8 Cl 2 f 6 N 2 o 3 , chemical name: N-[(3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenylaminocarbonyl]-2,6-difluorobenzamide, or 1- [3,5-Dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea; it kills by stomach, contact It works mainly by inhibiting the synthesis of chitin, hindering the normal peeling of insects, causing eggs to hatch, larvae peeling and pupae to develop abnormally, adult emergence is blocked, the drug effect is high, and the speed of action is slow. Highly active in Pteroptera, Coleoptera, Hymenoptera, Diptera, etc. Hexaflumuron has low toxicity and has no phytotoxicity to plants under effective dosage, and is beneficial to beneficial organisms such as birds, fish, frogs, bees, ladybugs, and carapac...

AI Technical Summary

Problems solved by technology

[0005] 1. The work efficiency of the conventional spraying method is low, and the work efficiency per capita is usually only 2-5 mu / day, which is difficult to meet the needs of large-scale planting

[0006] 2. Conventional spraying method needs a lot of water to control diseases and insect pests, usually the water consumption is 450~900L / hm 2 , and in many areas far away from water sources and arid and water-scarce areas, conventional spraying methods are difficult to implement or cannot achieve the desired control effect

[0007] 3. The medicines used in the conventional spraying method have a short duration of action. Since the dosage forms of the medicines used in the conventional spraying method are usually emulsifiable concentrates, water preparations, wettable powders, suspension concentrates, and water-emulsions, there are certain defects in use:

[0008] (1) Due to the addition of a large amount of water for dilution, the concentration of the medicinal solution is very low, and the surface tension is often high. The adhesion, wettability, and permeability on the surface of the crop or target with a waxy layer are poor, and it is difficult to effectively enter In crops and targets, resulting in poor control effect;

[0009] (2) In the natural environment of light, high temperature, and dryness, the water in the liquid medicine is easy to evaporate, causing the medicine to only remain on the surface of the crops, and it is easy to fall off from the crops after photolysis and drying to become ineffective;

[0010] (3) The droplet size of conventional spraying is relatively large, reaching 200-600 μm, which leads to the easy loss of the liquid medicine sprayed on the surface of crops or targets

[0011] (4) For a long time, the single and frequent use of pesticide varieties has increased the resistance of biological targets to the pesticide itself, which is not conducive to the prevention and control of harmful organisms

[0012] (5) Agricultural and forestry crop pests such as locusts and tree loopers are explosive crop pests. Once they break out, they will bring a major threat to human food security and the ecological environment, and conventional pesticide application methods are difficult to work

The composition prepared by the invention is a conventional dosage form, requires a large amount of water, and is not practical enough for areas lacking
