Example Embodiment

[0016] Bioassay Example 1: Determination of the virulence of picoxystrobin and Dysenlion against Apple anthracnose

[0017] The indoor virulence of the mixture of picoxystrobin and dysenlion to the 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.

[0018] (CTC) to evaluate the effect of mixing. When the CTC value is greater than 120, the mixture is considered to have a synergistic effect, when it is less than 80, it is considered to have an antagonistic effect, and when it is between 80 and 120, it is considered to have an additive effect. The specific method is as follows:

[0019] 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 adde...

Abstract

The invention relates to a sterilization composition containing picoxystrobin and thioneb and application of the composition. According to the composition, the weight part ratio of picoxystrobin to thioneb 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 thioneb and is used for preventing and controlling various diseases such as leaf spot disease, anthracnose, downy mildew, brown blotch, gummy stem blight and rice false smut on various crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition containing picoxystrobin and disenlian and an application thereof. technical background [0002] In recent years, with the adjustment of the rural planting structure, the planting area of ​​fruit trees has been increasing, and the occurrence of many diseases on fruit trees has also increased. Because old agents have been used, such as thiophanate-methyl, mancozeb and other agents that have been used for many years, the resistance of pathogenic bacteria to these agents has increased rapidly, and the control effect has continued to decline, resulting in more and more diseases. It is very urgent to find new varieties of fungicides with excellent control effect. [0003] Picoxystrobin, chemical name: (E)-3-methoxy-2-[2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl]methyl acrylate. Methoxyacrylate fungicide is a kind of low toxicity, high e...
