Embodiment 10

[0038] Embodiment 10.5% prothioconazole ultra-low volume liquid

[0039] According to the following weight ratio:

[0040]

[0041] Preparation method: at normal temperature and pressure, weigh the raw materials according to the weight percentage, first put the solvent into the reaction kettle, put in the active ingredients at a stirring speed of 60 rpm, and put in the co-solvent and the surface after the active ingredients are completely dissolved. The active agent was stirred for 60 minutes to obtain a homogeneous and transparent oily product.

Embodiment 23

[0042] Embodiment 23% prothioconazole ultra-low volume liquid

[0043] According to the following weight ratio:

[0044]

Abstract

The invention discloses ultra-low-volume liquid containing prothioconazole. The ultra-low-volume liquid adopts a first active ingredient or the first active ingredient and a second active ingredient as effective ingredients, and the balance comprises surfactants, cosolvents and solvents supplemented to 100 percent. The first active ingredient is prothioconazole, the second active ingredient is any one kind of materials from difenoconazole, hexaconazole, isoprothiolane, pyraclostrobin, metalaxyl, chlorothalonil and dimethomorph. The first active ingredient accounts for 0.5 to 10 weight percent, the second active ingredient accounts for 0 to 20 weight percent, the surfactants account for 1 to 15 weight percent, and the cosolvents and the solvents are used for supplementing the volume to 100 percent. The ultra-low-volume liquid has the advantages that the efficacy is high, pesticide can be saved during the spraying, the medicine effect is good, the effect lasting period is long, prevention and treatment cost is low, in addition, the synergetic effects are realized, and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an ultra-low volume liquid containing prothioconazole. Background technique [0002] Ultra-low volume liquid is a pesticide formulation suitable for ultra-low-volume spraying. Ultra-low-volume spraying is an advanced new technology for pesticide application with the emergence of ultra-low-volume spraying equipment, because its droplets are uniform in fineness The oily mist droplets are easy to adhere to the crops, and the loss of mist droplets is small, so the utilization efficiency of pesticides is high. Compared with conventional spray-applied pesticide formulations, it has the following characteristics: [0003] 1. The spray volume is low, 60-330mL / mu, which is one hundredth of the conventional spray volume; [0004] 2. The droplets are fine, and the particle size range of ultra-low volume liquid is 20-100 μm, while the diameter of conventional droplets is 200-600 μm. The...
