Problems solved by technology

[0002] In recent years, the occurrence of bacterial diseases of various crops has shown a trend of increasing year by year, and the area of ​​occurrence has increased year by year, which has brought great harm to agricultural production. At present, there is a lack of better agents for preventing and controlling bacterial diseases on the market or strong resistance. Reduced effectiveness
Secondly, in order to improve the control effect, farmers increase the dosage or mix another kind of pesticide at will. This kind of unscientific use of medicine not only fails to achieve synergistic effect and improve the control effect, but also leads to the waste of pesticides and the residue exceeds the standard.

preparation Embodiment

[0055] In addition to active ingredients, the fungicidal composition of the present invention may also include functional auxiliaries and fillers suitable for agricultural use in pesticide formulations. That is to say, the composition of the present invention can be added with functional additives, fillers and other auxiliary materials to prepare wettable powders, suspension concentrates, water-dispersible granules, and seed coatings.

[0056] In some embodiments provided by the present invention, the auxiliary agents include surfactants, wetting agents, dispersants, and if necessary, antifreeze agents, thickeners, stabilizers, defoamers, disintegrants, film forming agent, etc.

[0057] 1. Preparation of wettable powder

[0058] Mix mesycloconazole, zinc thiazole, wetting and dispersing agent, white carbon black, and filler evenly, pulverize in a jet mill, and stir for 30 minutes to obtain the wettable powder of the fungicide of the present invention.

Embodiment 1

[0060] 90% active compound (composition of 80% mesylconazole and 10% thiazole zinc), 5.0% sodium methylene bismethyl naphthalene sulfonate, 2.0% sodium lauryl sulfate, 1.0% white carbon black, Diatomaceous earth 2.0% was mixed thoroughly, pulverized by a jet mill, and stirred for 30 minutes to obtain a wettable powder with 90% active compound.

Embodiment 2

[0062] 32% active compound (30% mesycloconazole and 2% thiazole zinc composition), 2% sodium polyacrylate, 4% naphthalenesulfonate formaldehyde condensate sodium salt, 62% kaolin were fully mixed, and pulverized by a jet mill After that, stir for 30 minutes to obtain wettable powder with 32% active compound.

Abstract

The invention discloses a compound composition containing methanesulphonyl myclobutanil and zinc thiazole and a preparation. The compound composition takes the methanesulphonyl myclobutanil and the zinc thiazole as active ingredients, wherein the chemical name of the methanesulphonyl myclobutanil is 2-(p-fluorophenyl)-5-methylsulfonyl-1,3,4-oxadiazole; the weight ratio of the methanesulphonyl myclobutanil to the zinc thiazole is (20-1):(1-40); the active ingredient composition is 0.1-90% of the preparation in the aspect of weight. The compound composition is capable of effectively controlling various bacterial diseases such as citrus canker, rice bacterial streak and tobacco bacterial wilt, has the function of killing bacteria and fungi, is capable of efficiently supplementing zinc to correct the zinc deficiency and is an efficient therapeutic agent in plants. The compound of the methanesulphonyl myclobutanil and the zinc thiazole has remarkable synergistic interaction effect, is capable of decreasing the pesticide application dosage, decreasing the medicament dosage, reducing the cost and delaying the drug resistance and brings therapeutic effect to the plants.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition and preparation containing mesylconazole and zinc thiazole. Background technique [0002] In recent years, the occurrence of bacterial diseases of various crops has shown a trend of increasing year by year, and the area of ​​occurrence has increased year by year, which has brought great harm to agricultural production. At present, there is a lack of better agents for preventing and controlling bacterial diseases on the market or strong resistance. Reduced effectiveness. Secondly, in order to improve the control effect, the farmers increase the dosage or mix another pesticide at will. This kind of unscientific application will not only fail to achieve synergistic effect and improve the control effect, but will lead to the waste of pesticides and excessive residues. Therefore, there is an urgent need to develop a synergistic bactericidal composition. [...
