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

[0029] Biological Assay Example 1: Indoor Toxicity Determination of Flumorph and Benzamid or Penthiopyrad or Mandipyrad Compounded to Cucumber Downy Mildew

[0030] Test object: Cucumber downy mildew (Pseudoperonospora cubensis)

[0031]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...

[0067] Embodiment 2: 10.1% flumorph Penthiopyrad suspension concentrate

[0068] Flumorph 0.1%, penthiopyrad 10%, polycarboxylate (dispersant) 10%, tea dry powder (wetting agent) 3%, polyvinyl alcohol (thickener) 2%, bentonite (thickener) agent) 1%, ethylene glycol (antifreeze) 5%, and water to make up to 100%.

Embodiment 3

[0069] Example 3: 30.3% flumorph·mandipropamid suspension concentrate

[0070] Flumorph 30%, mandipropamid 0.3%, sodium lignosulfonate (dispersant) 10%, sodium lauryl sulfate (wetting agent) 3%, xanthan gum (thickener) 2 %, polyvinyl alcohol (thickener) 1%, propylene glycol, (antifreeze agent) 5%, water to make up to 100%.

Abstract

The invention relates to a fungicidal composition containing flumorph, of which the effective component is one of flumorph (A) and fenamiphos-sulfone, penthiopyrad and mandipropamid (B), the mass ratio of A and B is between 100:1 and 1:100, and the mass percentage of the active components in the composition is 10-80%. The composition can be prepared to suspending agent, wettable powder and water dispersing granule. The fungicidal composition can be applied in the farmland and orchard and is used for preventing various plant diseases, particularly the downy mildew and epidemic disease on the crops such as grain, vegetables, fruit tree and flowers.

Description

technical field [0001] The invention relates to a bactericidal composition, especially a bactericidal composition containing flumorph and benzamid or penthiopyrad or mandiprod, the composition has protective, preventive and therapeutic effects, and belongs to agricultural fungicides field. 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 stage ...
