Pyraclostrobine and tebuconazole compound suspending agent and preparation method thereof

Abstract

The invention discloses a pyraclostrobine and tebuconazole compound suspending agent and a preparation method thereof, and relates to the technical field of wheat scab prevention and control. The pyraclostrobine and tebuconazole compound suspending agent is prepared from at least 10 parts of pyraclostrobine, 30 parts of tebuconazole, 3 parts of primary alcobol ethoxylate, 3 parts of styrylphenol polyoxyethylene ether, 0.3 part of xanthan gum, 0.4 part of sodium benzoate, 0.3 part of defoaming agent and the balance being deionized water. All raw materials are pumped into a preparation reactor, and then are mixed and stirred, ground primarily by a colloid mill, and ground fine by a sand mill; the ground substance is sampled and analyzed until being qualified; and the qualified substance is then filtered, metered, packaged and put into storage. The 40% pyraclostrobine and tebuconazole compound suspending agent prepared from pyraclostrobine and tebuconazole according to the ratio of 1:3 has the advantage of expanding range of action significantly, which is incapable of being achieved by the preparation prepared from pyraclostrobine and tebuconazole according to the other ratio.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of wheat scab, in particular to a compound suspending agent of pyraclostrobin and tebuconazole and a preparation method thereof. Background technique [0002] At present, the existing fungicidal composition for preventing and treating wheat scab, for example, Chinese patent CN 105439727 A discloses a kind of "biological organic fertilizer for preventing and treating wheat scab", and its raw materials include: crop straw 30-40 40-60 parts of traditional Chinese medicine dregs, 3-5 parts of functional bacteria, 1-6 parts of urea, 0.5-2.5 parts of straw fermentation bacteria agent, 1-2 parts of cellulase, and 0.5-2 parts of brown sugar. Another Chinese patent CN 104106580 A discloses a "composite fungicide for preventing and treating wheat head blight", which uses albazole and tebuconazole as base materials, and according to the ratio of albendazole and tebuconazole 7:1 to 1:7 It is...

Problems solved by technology

For example, wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and causes precipitation in the sprayer, resulting in uneven spraying

[0006] 3), the problem of compounding, through the toxicity test, heat storage stability test and the determination of the mixed co-toxicity coefficient of several specific proportions disclosed by the above-mentioned several bactericidal compositions, it was found that no obvious synergistic effect could be achieved
