Problems solved by technology

Due to the long-term use of these agents, they have produced different degrees of drug resistance, and the control effect is reduced.
At the same time, the extensive use of medicaments increases pesticide residues, endangers food safety, and aggravates environmental pollution.

Embodiment 1

[0026] Biological Assay Example 1: Indoor Toxicity Determination of Dikrysstrobin Combined with Penthiopyrad or Mandipropamid to Cucumber Downy Mildew

[0027] Test object: Cucumber downy mildew (Pseudoperonospora cubensis)

[0028] The potted method was used in this experiment. Two cucumber seedlings at the true leaf stage with the same growth were selected, and 5 pots of cucumber seedlings for testing were selected for each treatment, and the numbers were reserved for future use. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot. Five concentration gradients were set for each agent, and the same amount of water sprayed was used as the blank control. Spray and inoculate the sporangia suspension of cucumber downy mildew after 24 hours of chemical treatment. sporangia, the concentration is 3×10 5 sporangia suspension per mL. After inoculation, cucumber seedlings were placed in an artificial climate box (relative humidity 100%, temperature 15-20°C) for cul...

Embodiment 2

[0056] Example 2: 5% dikestrobin·mandiprodil suspension concentrate

[0057] Phenostrobin 1.5%, mandipropamid 3.5%, sodium methylnaphthalenesulfonate formaldehyde condensate (dispersant) 10%, sodium lauryl sulfate (wetting agent) 3%, polyvinyl alcohol (enhancer) thickener) 2%, xanthan gum (thickener) 1%, sodium chloride (antifreeze) 5%, and water to make up to 100%.

Embodiment 3

[0058] Example 3: 20.2% dikestrobin · penthiopyrad suspension concentrate

[0059] Dikestrobin 20%, Penthiopyrad 0.2%, Sodium methylnaphthalene sulfonate formaldehyde condensate (dispersant) 10%, Sodium lauryl sulfate (wetting agent) 3%, Xanthan gum (thickener 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 any one (B) selected from penthiopyrad and mandipropamid, wherein 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 5-80 percent. The compound can be prepared into any preparation allowable in agriculture, and better preparation forms include 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 of downy mildew and epidemic diseases 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 dikestrobin and penthiopyrad or mandiprodil. The composition has protective, preventive and therapeutic effects, and belongs to the field of agricultural fungicides. Background technique [0002] Downy mildew is one of the most important diseases in the production of melons, fruits and vegetables. Among melons, cucumbers, loofahs, bitter gourds, and muskmelons are common and severely damaged. Downy mildew is a highly prevalent disease. In the vegetable area where no disease-resistant varieties are planted, the disease can reduce yield by 30-40% when the disease is prevalent, and reach more than 70-80% in severe cases, and even destroy the seeds. [0003] Downy mildew can occur at all stages from seedlings to harvest, and the adult plants suffer the most. It mainly damages the leaves and develops from the base to the upper leaves. In the early s...
