Embodiment 1

[0023] Rice blast spirit 40%, propiconazole 2%, calcium dodecylbenzenesulfonate (Nongru 500 # ) 4.5%, castor oil and ethylene oxide condensate (nong milk BY-140#) 5%, heparinate 1%, xylene is supplemented to 100% (all are weight %, following examples are the same). According to the formula requirement, add solvent, original drug and emulsifier respectively, mix evenly, and heat and dissolve in a hot water bath if necessary, to obtain a transparent emulsifiable concentrate with a content of 42%.

Embodiment 2

[0025] Rice blastling 0.5%, difenoconazole 15% (, Nongru 500 # 5%, alkylphenol formaldehyde resin polyoxyethylene ether (Nongru 700 # )3%, condensates of phenethylphenol and different proportions of ethylene oxide and propylene oxide (Nongru 602 # ) 2%, and xylene was added to 100%. The preparation method is the same as in Example 1 to obtain a transparent emulsifiable concentrate with a content of 15.5%.

Embodiment 3

[0027] Rice blast spirit 1%, triadimefon 15%, agricultural milk 500 # 5%, Farm Milk 700 # 3%, anyylphenol polyoxyethylene ether 4%, cyclohexanone 10%, toluene to make up to 100%. The preparation method is the same as in Example 1 to obtain a transparent emulsifiable concentrate with a content of 16%.

Abstract

The invention relates to a sterilization pesticide composition, which comprises effective drug ingredients of isoprothiolane and triazole fungicide as well as pesticide-acceptable auxiliary components, wherein the weight ratio of the isoprothiolane to the triazole fungicide is 40:1-1: 60. By the synergy generated by the combination of two effective drug ingredients with different sterilization mechanisms, the sterilization pesticide composition can improve the sterilizing effect and the using safety remarkably, and can reduce the using cost. The composition can be prepared into different dosage forms of missible oil, wettable powders, suspensions, emulsions, granules, and the like for preventing and treating plant diseases caused by the majority of pathogenic fungi such as ascomycetes, basidiomycetes and imperfect fungi, in particular cereal crop diseases such as rice blast and sheath blight, wheat sheath blight, and the like.

Description

technical field [0001] The invention relates to a fungicidal pesticide composition, in particular to a fungicidal pesticide composition compounded with rice blastyl and triazole fungicides. Background technique [0002] Isoprothiolane (isoprothiolane), the chemical name is 1,3-dithiolane-2-ylidene-diisopropyl malonate, and its structure is as shown in formula (I). It is a systemic drug with special effects on rice blast Sexual fungicides. The drug absorbed by the rice plant can accumulate in the leaf tissue, especially concentrated in the cob and branch, inhibiting the invasion of pathogens, especially inhibiting the phospholipid N-methyltransferase, thereby inhibiting the growth of pathogenic bacteria and playing a corresponding control role. Due to the long-term and repeated use of Daoblastin in rice production areas and other crops, the resistance of pathogenic bacteria to it has gradually increased, resulting in an increase in the use of Daoblastin for disease control a...
