Embodiment

[0063] The following examples are only to further illustrate the present invention, but are not intended to limit the present invention to these specific examples. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

Embodiment 1

[0066] Embodiment 1: 44% erythrostrobin · rice blastling suspension concentrate

[0067] Weigh 4g of the original drug of fenoxastrobin, 40g of the original drug of Daobunling, 5g of FS3000 (phosphate ester anionic surfactant), 1g of TXC (sulfonate anionic surfactant), 0.3g of xanthan gum, and 1g of magnesium silicate Aluminum, 4g of ethylene glycol, 0.2g of BIT (1,2-benzisothiazolin-3-one), 0.3g of organomodified silicone defoamer, and deionized water were added to 100g. Add the above-mentioned raw materials into a high-shear emulsifier and shear for 10 minutes, and then grind them with a sand mill to obtain a suspending agent.

Embodiment 2

[0068] Example 2: 42% erythrostrobin · rice blastin emulsifiable concentrate

[0069] Weigh 2g of the original drug of fenoxastrobin, 40g of the original drug of Daobunling, 4g of calcium dodecylbenzenesulfonate, 1g of styrene ethylphenol polyoxyethylene ether, 2g of nonylphenol polyoxyethylene ether, and add xylene to 100g. Mix to a homogeneous liquid to make a composition emulsifiable concentrate.

Abstract

The invention belongs to the field of pesticides, and particularly relates to an agricultural sterilization composition with fenaminstrobin and isoprothiolane as active ingredients. The composition is mainly used for preventing and treating fungal diseases such as rice blast, and meanwhile has the characteristics that the crop quality is improved and the crop yield is increased. The composition has more acting mechanisms and sites, can effectively delay the occurrence and the development of drug resistance of pathogens, is simple in preparation process, is low in cost and has an obvious economic benefit.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular is a pesticide composition using enoxistrobin and rice blastin as active ingredients; it is used for preventing and treating fungal diseases of crops, especially for preventing and treating rice blast. Background technique [0002] Fenaminstrobin is a methoxyacrylate fungicide developed by Shenyang Research Institute of Chemical Industry in 1999 and obtained a Chinese invention patent in 2003; its chemical name is (E, E, E)-N-methyl-2 -[2-((((1-methyl-3-(2,6-dichlorophenyl)-2-propenyl)imino)oxy)methyl)phenyl]-2-methoxyphenyl Aminoacetamide, CAS number 366815–39–6. Has the following structural formula: [0003] [0004] Enoxastrobin has a good control effect on a variety of plant diseases on grains, fruit trees, vegetables and other crops, especially for powdery mildew, rust and leaf spot. It has a wide bactericidal spectrum and high activity, and has preventive and therapeutic ef...
