Embodiment 1

[0018] Bioassay Example 1: Determination of the virulence of picoxystrobin and difenoconazole against Apple anthracnose

[0019] The indoor virulence of a mixture of picoxystrobin and difenoconazole on apple anthracnose bacteria was studied by the mycelial growth rate method. The experimental method used Sun Yunpei’s method to calculate the co-toxicity coefficient (CTC) to evaluate the mixed effect. When the CTC value is greater than 120, the mixture is considered to have synergistic effect, when it is less than 80, it is considered to be antagonistic, and when it is between 80 and 120, it is considered to have an additive effect. The specific method is as follows:

[0020] Take the prepared drug solution and place it in 100ml of 50-60℃ PDA sterilized medium, shake it, and pour it into a sterile petri dish with a diameter of 60mm. After cooling and solidification, transfer the bacteria cakes with a uniform growth and a diameter of 4mm. The sterile medium added with the same amount...

Abstract

The invention relates to a sterilization composition containing picoxystrobin and difenoconazole and application of the composition. According to the composition, the weight part ratio of picoxystrobin to difenoconazole is (40 to 1) to (1 to 40) and the weight percent of active ingredients is 1-90%. The composition has a synergistic effect by compounding picoxystrobin with difenoconazole and is used for preventing and controlling various diseases such as leaf spot disease, anthracnose, downy mildew, brown blotch, gummy stem blight, rice false smut and rust disease on various crops such as bananas, apples, paddy rice, watermelons and hot peppers.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a bactericidal composition containing picoxystrobin and difenoconazole and its application. technical background [0002] Picoxystrobin (picoxystrobin), chemical name: (E)-3-methoxy-2-[2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl]methyl acrylate. Methoxyacrylate fungicides are a class of low-toxicity, high-efficiency, broad-spectrum, systemic fungicides, which have almost all fungi (Oomycetes, Algae, Ascomycetes and Deuteromycetes) diseases such as Powdery mildew, rust, glume blight, net spot, downy mildew, rice blast, etc. have good activity, and can effectively prevent and control pathogens that are resistant to other fungicides. It is resistant to 14-demethylase Strains resistant to inhibitors, benzamides, dicarboxamides and benzimidazoles are effective. There is no cross-resistance with other fungicides currently used in the domestic market, and it can be quick...
