Embodiment 1

[0017] Embodiment 1, a kind of bactericidal composition, comprises following material: Isotianil 1g, Wuningmycin 30g, difenoconazole 5g, fatty alcohol polyoxyethylene ether 10g, glycerol 20g, xanthan gum 6g , water 30g. Preparation: adopt the conventional method, after the solid original drug is sand-milled to a fineness of 2-3 microns, add the liquid original drug, surfactant, solvent and mix evenly, use a high-shear disperser to shear for 30 minutes, and then mix evenly to obtain Suspoemulsion type fungicide.

Embodiment 2

[0018] Embodiment 2, a bactericidal composition, comprising the following materials: Isotianil 30g, Wuningmycin 1g, difenoconazole 5g, fatty alcohol polyoxyethylene ether 10g, glycerol 20g, xanthan gum 6g , water 30g. Preparation: adopt the conventional method, after the solid original drug is sand-milled to a fineness of 2-3 microns, add the liquid original drug, surfactant, solvent and mix evenly, use a high-shear disperser to shear for 30 minutes, and then mix evenly to obtain Suspoemulsion type fungicide.

Embodiment 3

[0019] Example 3, a bactericidal composition comprising the following substances: 10 g of Isotianil, 1 g of Wuningmycin, 7 g of sodium lignosulfonate, 15 g of silicone oil, 8 g of glycerol, 2 g of xanthan gum, and 19 g of water. Preparation: adopt conventional method, mix each component such as active ingredient, dispersant, wetting agent and water according to the ratio of the formula, and obtain the bactericidal combination suspension concentrate after grinding and / or high-speed shearing.

[0020] The control effect of Example 1 on cucumber anthracnose is as follows: first count the total number of cucumber anthracnose, and then use the pesticide composition with a concentration of 30g / mu. After one week of use, the control effect accounts for 85.2% of cucumber anthracnose, and use it for 2 weeks The post-control effect accounts for 93.2% of cucumber anthracnose; using the pesticide composition with a concentration of 40g / mu, the control effect accounts for 86.5% of cucumber ...

Abstract

The invention belongs to the technical field of fungicide and relates to a sterilization composition. Effective components in the sterilization composition comprise isotianil and tetramycin and the weight ratio of the isotianil to the tetramycin ranges from (1 to 30) to (30 to 1). According to the sterilization composition provided by the invention, two effective components including the isotianiland the tetramycin are compounded, so that the sterilization composition has a good effect of preventing and controlling watermelon anthracnose, tomato early blight, celery leaf spot or corynespora cassiicola, and a pesticide spraying process in a process of planting different vegetables in a large area is greatly convenient to realize; the utilization amount of each pesticide single dosage is reduced, and the sterilization composition has the advantages of prolonging the drug resistance of plants, prolonging the effective time of drugs and the like, and has very high actual application valueand popularization value; meanwhile, the sterilization composition has a wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of fungicides and relates to a fungicide composition. 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, shrinking, or even reversing. 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 the immature fruit, the initial lesion is water-soaked, light green round spot, and on the mature fruit, it starts to be a raised lesion, which expands into a brown depression i...
