Problems solved by technology

The long-term use of Sclerotin to prevent and control rice sheath blight has also led to a significant decline in the current efficacy, which can no longer meet the needs of preventing and controlling rice sheath blight and ensuring the normal growth of crops.

Embodiment 1

[0022] Sclerotia net 60%, propiconazole 1.5%, sodium lignosulfonate 5%, methylnaphthalenesulfonic acid formaldehyde condensate 3%, sodium dodecylbenzenesulfonate 3%, white carbon black 15%, kaolin supplement Remain. The original drug, various additives and fillers are fully mixed and then crushed by airflow to obtain a 61.5% wettable powder product.

Embodiment 2

[0023] Preparation Example 2: (Sclerotinia: propiconazole=40:5)

[0024] Example 2

[0025] Sclerotinia net 30%, propiconazole 1%, sodium butyl naphthalene sulfonate 3%, alkyl naphthalene sulfonate formaldehyde condensate 7%, thilone 1%, light calcium carbonate supplement. The preparation method is the same as in Example 1 to obtain a 31% wettable powder product.

Embodiment 3

[0027] Sclerotia net 40%, propiconazole 2%, sodium alkylsulfonate 1%, sodium alkylsulfate 2.5%, sodium lignosulfonate 8%, kaolin supplement preparation method is the same as embodiment 1, obtains 42% wettability Powder products.

Abstract

The invention relates to a sterilizing pesticide composition, which uses dimethachlon and propiconazole as active drug components which are mixed together with the additives allowed to be used in farm chemicals, wherein the weight ratio of the dimethachlon to the propiconazole is 40:1-1:20, preferably 30:1-1:15. By properly mixing the two bactericides with different action mechanisms, the invention can provide the sterilizing composition which has the advantages of synergism, good sterilization effect, high safety and reduced use cost, which is particularly applicable to controlling the diseases of cereal crops including rice diseases, and the like.

Description

technical field [0001] The invention relates to a bactericidal pesticide composition with synergistic effect, more specifically a bactericidal pesticide composition for preventing and treating cereal crop diseases, especially rice sheath blight. Background technique [0002] Dimetachlone and Tricyclazole are two compounds with different mechanisms of action and bactericidal activity that have been reported and used in agriculture. [0003] The chemical name of sclerotin is N-(3,5-dichlorophenyl)succinimide, and its structure is shown in formula (I). The chemical name of propiconazole is 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2-methyl]-1hydro-1,2, 4 Triazoles, the structure of which is shown in formula (II). [0004] [0005] Propiconazole is a new type of systemic broad-spectrum fungicide with dual functions of treatment and protection. It can be absorbed by roots, stems and leaves, and can quickly conduct upwards in plants to prevent and control ascomycetes a...
