Embodiment 1

[0014] Composition (all by weight%, the same below: Difenoconazole 1,

[0015] Copper Nonyl 50,

[0016] Fatty alcohol polyoxyethylene ether 3.5,

[0017] Span-80 4.5,

[0018] Glycerol 5,

[0019] Xanthan gum 0.25,

[0020] Water to make up.

[0021] Preparation: Using the conventional method, the solid original drug is sand-milled to a fineness of 1-4 microns, then the liquid original drug, surfactant, and solvent are added to mix, and then the high-shear disperser is used to cut for 30 minutes and then mixed to obtain Suspoemulsion type fungicide.

Abstract

Disclosed are a bactericide composition, a bactericide pesticide and an application of the bactericide composition and the bactericide pesticide. The bactericide composition is composed of difenoconazole and cuppric nonyl phenolsulfonate, and the weight ratio between the difenoconazole and the cuppric nonyl phenolsulfonate is in the range of (1:50)-(50:1), preferably (1:25)-(25:1). The composition is combined with a helper component which is receptive in the pesticide to compose the bactericide pesticide; and the bactericide pesticide has obvious synergism effects on preventing diseases of watermelon anthracnose, tomato early blight, celery leaf spot or Corynespora cassiicola of cucumbers, the application amount of the single bactericide composition or the single helper component can be reduced, the lasting time of the bactericide pesticide can be prolonged, the generation of insecticide resistance of microbe diseases can be postponed, and the popularization values of the bactericide pesticide are obvious.

Description

technical field [0001] The invention relates to a bactericidal composition, specifically a bactericidal composition composed of difenoconazole and nonylcopper, the corresponding bactericidal pesticide and its application in preventing and controlling crop diseases. Background technique [0002] Watermelon anthracnose can occur throughout the growth period, but it occurs most severely in the middle and late stages of plant growth, causing fallen leaves to die and fruits to rot. When the seedlings are onset, round brown lesions appear on the cotyledons, and develop to dark brown at the base of the young stems, constricted, or even folded. When the disease occurs in the adult stage, water-soaked circular light yellow spots appear on the leaves, and then turn brown, with purple-brown edges, light brown in the middle, and concentric ring patterns. Lesions expand and merge with each other, which can easily cause leaf perforation and dryness. On immature fruits, the initial dise...
