Ultralow-volume solvent containing Flusilazole

Abstract

The invention discloses an ultralow-volume solvent containing Flusilazole. Flusilazole or an active ingredient compounded by Flusilazole and an active component B, an accessory ingredient and a solvent are prepared into the ultralow-volume solvent. The ultralow-volume solvent containing Flusilazole comprises the following ingredients in percentage by weight: 1-10% of Flusilazole, 0-20% of active component B, 1-15% of accessory ingredient and the balance of solvent. The ultralow-volume solvent containing Flusilazole is suitable for ultralow-volume spraying, low-volume spraying and electrostatic spraying, has the advantages of high work efficiency, water conservation, good quick effect, long persistent period and rain scouring washing resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an ultra-low volume liquid containing silazole. Background technique [0002] Fluosilazole, chemical name: bis(4-fluorophenyl)-(1H-1,2,4-triazol-1-ylmethyl)silane, belongs to triazole systemic fungicides, can inhibit sterols Demethylation destroys and prevents the biosynthesis of ergosterol, resulting in the failure of cell membrane formation and the death of pathogens. It is mainly used for the prevention and control of Ascomycetes, Basidiomycetes, half-knowledge fungi, apple scab, powdery mildew, cereals, Septoria spp., hookworms, etc. Various pathogenic bacteria on fungi and sweet berries, peanut leaf spot, but ineffective against oomycetes, and have special effects on pear scab. [0003] Difenoconazole, chemical name: 1-{2-[4-(4-chlorophenoxy)-2-chlorophenyl]-4-methyl-1,3-dioxolan-2-ylmethyl Base}-1H-1,2,4-triazole, which belongs to triazole systemic fungici...

AI Technical Summary

Problems solved by technology

[0013] 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; with the implementation of my country's land transfer policy, the land presents a trend of intensive management, and more and more The large agricultural planting households in my country have increased the continuous planting area of ​​crops; and with the aging of the population and the emergence of labor shortages in China, labor is gradually becoming a scarce resource, and the cost of labor is constantly increasing, and the cost of agricultural production is increasing; the seasonality of agricultural production is obvious , Pests and diseases often require a lot of manpower to control in a short period of time

[0014] 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

[0015] 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:

[0016] (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;

[0017] (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;

[0018] (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

[0019] (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

The invention improves the control effect to a certain extent, delays the resistance speed, and reduces the cost of use, but it is prepared into a conventional dosage form, and there are defects in the conventional dosage form
