Problems solved by technology

At present, insecticides containing dihalogenated pyrazole amide can only control insect pests, while fungicides containing thifuramide can only control diseases, but diseases and insect pests in the field often occur at the same time, such as the late stage of rice (cracking stage) Diseases such as rice blast and sheath blight occur at the same time as rice leaf rollers and other pests all year round. Farmers need to purchase insecticides and fungicides at the same time when rice breaks. Excessive use will cause waste and increase environmental pollution, that is, insufficient use will affect the quality of prevention and control
Moreover, some fungicides and insecticides are not suitable for mixing together due to chemical reactions and other reasons. Improper mixing can easily lead to problems such as a decline in the control effect
[0006] At present, there is no report on the simultaneous control of diseases and insect pests in rice by the combination of thifuramide and dihalogenated pyrazole amide

Embodiment 1

[0018] Example 1: 30% Thiofuramide · Dihalogenated Pyrazoleamide Suspension Concentrate

[0019] The following substances are all in weight ratio: Thiofuramide 15%, Dihalogenated Pyrazole Amide 15%, Alkylphenol Polyoxyethylene Ether 10%, Pulling Powder BX 10%, Hydroxymethyl Cellulose 2%, Glycerol 2% %, silicone oil 0.1%, and deionized water make up 100%. Mix the above active ingredients, dispersant, wetting agent, thickener, antifreeze, defoamer and deionized water, disperse with high speed shearing, and sand mill in a sand mill to form a highly dispersed and stable The suspension system can be used to prepare 30% Thiofuramide · Dihalogenated Pyrazole Amide Suspension Concentrate.

Embodiment 2

[0020] Embodiment 2: 40% Thiofuramide Dihalogenated Pyrazoleamide Emulsion in Water

[0021] The following substances are all in weight ratio: Thiofuramide 25%, Dihalogenated Pyrazole Amide 15%, N-Pyrrolidone 20%, Alkylphenol Polyoxyethylene Ether Sulfosuccinate 10%, Fatty Amine Polyoxyethylene Ether 5% %, resorcinol 1%, glycerin 1%, deionized water make up 100%. Mix the above active ingredients, solvents, emulsifiers, dispersants and stabilizers to form an oil phase, dissolve the antifreeze in water to form a water phase, slowly add the oil phase to the water phase under the action of a shearing machine, and continue to shear for about In 30 minutes, a 40% aqueous emulsion of thiofluxamide·dihalopyrazole amide can be prepared.

Embodiment 3

[0022] Embodiment 3: 25% Thiofuramide·dihalogenated pyrazole amide microemulsion

[0023] The following substances are all in weight ratio: Thiofuramide 15%, Dihalogenated Pyrazole Amide 10%, Cyclohexanol 10%, Methanol 5%, Nonylphenol Polyoxyethylene Ether 15%, Sodium Citrate 2%, Silicone 1.5%, double kill 2.5%, deionized water make up 100%. Dissolve the active ingredients completely in a solvent, then add emulsifier, stabilizer, penetrant, and synergist and mix evenly, and finally add deionized water, and after fully stirring, 25% thiofluxamide dihalopyridine can be prepared Azolamide microemulsion.

Abstract

The invention discloses a pesticide composition containing thifluzamide and dihalo-pyrazole amide, comprising a first effective ingredient thifluzamide, a second effective ingredient bis(halogenopyrazoleamide), and common auxiliary ingredients, wherein the mass ratio of thifluzamide to bis(halogenopyrazoleamide) is 10:1 to 1:10. The pesticide composition can provide effective prevention and treatment for various diseases and pests on rice, such as Chilo suppressalis, Cnaphalocrocis medinalis and banded leaf and sheath blight, and has the advantages such as wide control spectrum, low resistance developing speed, significant synergy and low control cost.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a binary compound compounded with thifuramide and a dihalogenated pyrazole amide as active ingredients, which is mainly used in the prevention and control of agricultural diseases and insect pests. Background technique [0002] Thiofuramide: It belongs to the thiazole amide fungicides, has strong systemic conductivity and long-lasting effect, and is a succinate dehydrogenase inhibitor. It is active against pathogenic fungi such as Rhizoctonia, Puccinia, Stiltia, Tilletia, Puccinia, and Sclerotinia, especially for diseases caused by Basidiomycetes such as striae Blight, blight and other special effects. [0003] Dihalogenated pyrazole amide: it belongs to 3-halogenated ethoxypyrazole amide compounds, which can efficiently activate the ryanodine receptor in insect cells and bind to it, causing the receptor channel to open abnormally for a long time, thereby Exc...
