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] Bioassay Example 1: Indoor virulence determination of any combination of activated esters and iprocarbam, benthiazil, 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 5sporangia suspension per mL. After inoculation, cucumber seedlings were placed in an artificial climate box (relative humidity 100%, temperatu...

Embodiment 2

[0067] Embodiment 2: 30.3% activated ester · iprocarbam suspension concentrate

[0068] 0.3% of activated ester, 30% of iprocarbam, 10% of polycarboxylate (dispersant), 3% of tea dry powder (wetting agent), 2% of polyvinyl alcohol (thickener), bentonite (thickener) ) 1%, ethylene glycol (antifreeze) 5%, and water to make up to 100%.

Embodiment 3

[0069] Embodiment 3: 30.3% activated ester · benthiazil suspension concentrate

[0070] Activated ester 30%, benthiazil 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 sterilizing composition containing active ester, which comprises effective components such as active ester (A) and one (B) of iprovalicarb, benthiavalicarb and propamocarb, wherein the weight ratio of the A and B is 100:1-1:100, and the content of the active component in the composition is 10-80 in percentage by weight. The composition can be prepared in to suspending agents, wetting powder, water dispersible granules, and the like. The sterilizing composition can be applied to farmlands, orchards and the like and is used for controlling various plantdiseases of grains, vegetables, fruit trees, flowers, and the like, in particular downy mildew and epidemic diseases.

Description

technical field [0001] The invention relates to a fungicidal composition, especially a fungicidal composition containing activated esters, iprocarbam 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....
