Super low volume liquid formulation containing trifloxystrobin

Abstract

The super low volume liquid formulation containing trifloxystrobin is prepared by using trifloxystrobin or trifloxystrobin and an active ingredient B as active components and adding auxiliary agent and solvent. The active ingredient B is selected from epoxiconazole, flusilazole, difenoconazole, propiconazole, myclobutanil, tebuconazole, tricyclazole, metalaxyl, chlorothalonil, carbendazim, prochloraz, isoprothiolane and fenoxanil. Weight percentage of each ingredient is as below: trifloxystrobin 0.5-15%, active ingredient B 0-20%, auxiliary agent 1-15% and solvent supplying to 100%. The invention has advantages of simple processing, high work efficiency, water saving, long persistent period, no target resistance generation, little environmental pollution and cooperation synergy, etc; and super low volume spraying, low volume spraying or super low volume electrostatic spraying can control a plurality of diseases of paddy rice, wheat, corn, vegetable, tobacco, tea tree, fruit tree and cotton, etc.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to ultra-low volume liquid preparations containing trifloxystrobin. Background technique [0002] Trifloxystrobin, chemical name: (2Z)-2-methoxyimino-2-[2-[[1-[3-(trifluoromethyl)phenyl]ethylideneamino]oxymethyl]benzene Methyl acetate, methoxyacrylate broad-spectrum low-toxicity fungicide, by locking cytochrome b and C 1 The electron transfer between them prevents the synthesis of cellular ATP, thereby inhibiting mitochondrial respiration and exerting an antibacterial effect. Trifloxystrobin is a new class of fluorinated fungicides successfully developed from the natural product Strobilurins as the lead compound of fungicides. It has the characteristics of high efficiency, broad spectrum, protection, treatment, eradication, penetration, systemic activity, resistance to rain erosion, and long lasting effect. It is effective against strains resistant to 1,4-demethylas...

AI Technical Summary

Problems solved by technology

[0017] 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

[0018] 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

[0019] 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:

[0020] (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 vivo of crops and targets, resulting in poor control effect;

[0021] (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 and become invalid;

[0022] (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

[0023] (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

[0024] The Chinese patent application number is: 200910074092.7, and the patent application document titled: "A Compound Fungicide and Its Application" discloses a compound of trifloxystrobin and prochloraz as the active ingredient, adding an emulsifier, dispersing The fungicide composed of agent, stabilizer and penetrating agent, the ratio of trifloxystrobin and prochloraz is 30:1~1:40, it can be prepared into wettable powder, emulsifiable concentrate, suspension concentrate, water dispersible granule, Water emulsion or microemulsion belongs to the conventional dosage form, and there are defects such as large water consumption in the process of use
