Problems solved by technology

If the suspension rate is too low, the pesticide particles will quickly settle at the bottom of the sprayer, and the local concentration will be too high, resulting in uneven application concentration in the field, affecting the control effect, and even causing phytotoxicity
[0005] At present, there are many problems in the suspension rate of triadimefon water-dispersible granules: first, the FAO standard requires that the suspension rate test be carried out after the thermal storage stability test, while many enterprises only measure the suspension rate of the product at room temperature, and use it as a quality indicator
[0006] However, the ubiquitous problem of commercially available triadim

Abstract

The invention discloses triazolone water dispersible granules capable of increasing heat storage suspension rate and stability and a production method. The triazolone water dispersible granules are prepared from the following components in parts by weight: 5 parts of triazolone, 0.1 to 1 part of a wetting agent, 0.1 to 2 parts of a dispersing agent A, 0.1 to 5 parts of a dispersing agent B, 0.1 to 4 parts of an adsorbent, and 0.1 to 5 parts of a disintegrating agent; the dispersing agent A is selected from at least one of polyoxyethylene ether, phosphate polyoxyethylene and EO/PO (Ethylene Oxide/Propylene Oxide) segmented copolymer surface active agents; the dispersing agent B is selected from at least one of lignosulfonate, alkyl naphthalene sulfonate, alkyl naphthalene sulfonate formaldehyde condensates and polycarboxylate. The test shows that the effective suspension rate and mass suspension rate of the triazolone water dispersible granules at normal temperature reach more than 90% and are close to 90% under the thermal storage condition; compared with the prior art, the triazolone water dispersible granules have the advantages that the suspension rate is reduced a little, the mass suspension rate and the effective suspension rate are consistent, and the suspension rate in the thermal storing condition is high in stability.

Description

technical field [0001] The invention relates to the field of pesticide preparations and production thereof, in particular to a triadimefon water-dispersible granule with improved heat storage suspension rate and stability and a production method. Background technique [0002] Triadimefon is also known as Fenxioning and Beston, its chemical name is 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)-2 - butanone, a broad-spectrum triazole fungicide with high efficiency, low toxicity, low residue, long duration and strong systemicity developed by German Beyer company in the early 1970s, when it is used by plants After each part is absorbed, it can conduct in the plant body. Triadimefon has an excellent control effect on wheat powdery mildew, rust, smut, corn head smut, round spot, etc. It is effective against wheat take-all, moire, root rot, melons, fruit trees Powdery mildew in plants, vegetables, flowers, etc. has a high control effect. [0003] According to the ch...
