Embodiment 1

[0027] Bioassay Example 1: Indoor virulence determination of fenoxystrobin and propoxyquin or phenoxyquinoline against wheat powdery mildew

[0028] Test object: wheat powdery mildew (collected from the field, indoor live culture preservation)

[0029] Test method: Refer to "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". Potted wheat seedlings at the 3-4 leaf stage with consistent growth potential were selected, and 5 pots were selected for each treatment, numbered for use. Use Potter spray tower to spray at 50PSI pressure, 5mL per pot. See Table 1, Table 2, and Table 3 for the test treatment, and set 5 concentration gradients for each agent. The inoculation concentration after 24h is 3×10 5 A spore / mL conidia suspension of powdery mildew fungus. The wheat seedlings sprayed with the same amount of water were used as the blank control. After inoculation, the wheat seedlings are cultivated in a greenhouse. After 10 days, the disease index of the whol...

Embodiment 2

[0057] Example 2: 10% fenoxystrobin·phenoxyquinoline suspension

[0058] Difenoxystrobin 6.5%, phenoxyquinoline 3.5%, sodium methyl naphthalene sulfonate formaldehyde condensate (dispersant) 10%, sodium lauryl sulfate (wetting agent) 3%, polyvinyl alcohol (thickening) Agent) 2%, xanthan gum (thickener) 1%, sodium chloride (antifreeze) 5%, and water to make up to 100%.

Embodiment 3

[0059] Example 3: 20.2% fenoxystrobin·propoxyquin suspending agent

[0060] Diphenoxystrobin 20%, Propoxyquin 0.2%, sodium methyl naphthalene sulfonate formaldehyde condensate (dispersant) 10%, sodium lauryl sulfate (wetting agent) 3%, xanthan gum (thickening Agent) 2%, bentonite (thickener) 1%, glycerin (antifreeze) 5%, and water to make up to 100%.

Abstract

The invention relates to a sterilization compound containing ZJ0712. The effective components comprise ZJ0712 (A) and a quinoline bactericide (B), wherein the quinoline bactericide is proquinazid or benzoquinate, the weight ratio of A to B is 100:1 to 1:100, and the weight percentage of the active component in the compound is 10-80 percent. The compound can be prepared into suspending agent, wettable powder, water dispersible granules and the like. The sterilization compound is suitable for farmlands, orchards and the like and is used for preventing and treating multiple plant diseases especially powdery mildew of crops such as corns, vegetables, fruit trees, flowers and the like.

Description

Technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing fenoxystrobin and a quinoline bactericide, belonging to the field of agricultural bactericides. Background technique [0002] Powdery mildew is a plant disease caused by the Erysiphacesae family of fungi. Powdery mildew is widespread all over the world, and it is especially common to damage dicotyledonous plants. The main powdery mildews in China are cereal powdery mildew caused by Ery-siphe graminis; powdery mildew caused by Sphaerothecafuliginea in melons, beans, hemp and other plants; Grape powdery mildew caused by Uncinula necator; powdery mildew caused by Phyllactinia corylea in more than 80 trees including mulberry, pear, persimmon, walnut, chestnut, litchi, and papaya; The powdery mildew of rose flowers caused by Sphaerotheca pannosa. [0003] When powdery mildew first occurs, the leaves produce small yellow spots, and then expand into round o...
