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 virulence determination of any combination of flumorph and iprocarbam, benthiocarbam, and propamocarb against 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%, tempe...

Embodiment 2

[0069] Embodiment 2: 40.4% flumorph · iprocarbam suspension concentrate

[0070] Flumorph 0.4%, Promethacarb 40%, Polycarboxylate (dispersant) 10%, Chaku powder (wetting agent) 3%, Polyvinyl alcohol (thickener) 2%, Bentonite (thickener) agent) 1%, ethylene glycol (antifreeze) 5%, and water to make up to 100%.

[0071] This embodiment is applied to control grape downy mildew. The test site is Yueyang, Hunan. Apply the first medicine at the early stage of the onset, and carry out the second medicine seven days later. Investigate the condition index before the medicine and seven days after the second medicine. Embodiment 2 is processed by 135g (a.i.) / ha, and the control effect of 14 days after the medicine is 93.1%; 50% flumorph wettable powder is pressed by 150g (a.i.) / ha and 30% propacarbamide wettable powder is pressed by 150g (a.i.) / ha treatment, the control effects were 82.5% and 81.4% respectively 14 days after application. The synergistic effect of flumorph and iproca...

Embodiment 3

[0072] Embodiment 3: 30.3% flumorph · benthiazil suspension concentrate

[0073] Flumorph 30%, Benthiopyram 0.3%, Lignosulfonic acid sodium salt (dispersant) 10%, saponin powder (wetting agent) 3%, xanthan gum (thickener) 2%, polyethylene Alcohol (thickener) 1%, propylene glycol (antifreeze) 5%, water to make up to 100%.

[0074] This embodiment is applied to the prevention and treatment of tobacco black shank. The test site is Yongzhou, Hunan. Apply the first medicine at the early stage of the onset, and carry out the second medicine ten days later. Investigate the condition index before the medicine and ten days after the second medicine. Embodiment 3 is processed by 65g (a.i.) / ha, and the control effect of 20 days after the medicine is 90.2%; 50% flumorph wettable powder is pressed by 150g (a.i.) / ha and 20% benthiazil wettable powder is pressed by 75g (a.i.) / ha treatment, the control effects were 78.3% and 81.7% at 20 days after treatment. The synergistic effect of flu...

Abstract

The invention relates to a fungicidal composition containing flumorph, of which the effective component is one of flumorph (A) and iprovalicarb, benthiavalicarb-isopropyl and propamocarb (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 20-80%. 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, iprocarbamide or benthienil or propamocarb. 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 fruits and vegetables. All stages can occur 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 of the disease, light yellow sub-circular to polygonal lesions are formed on the leaves. When the air is humid, a frosty mold layer is formed on the back of the leaves, and sometimes it can spread to the leaves. In the later stage, the disease spots are withered and contiguous, and they are yellowish brown. In severe cases, all the outer leaves are withered and yellow and die. ...
