Problems solved by technology

[0004] In recent years, due to single drug use and unscientific drug use methods, many pathogenic bacteria such as powdery mildew and downy mildew have developed resistance to many currently used pesticides, and the resistance is becoming more and more serious. The increase in dosage and frequency of spraying not only increases the cost of prevention and control, but also aggravates the environmental pollution, which has become a major problem in chemical prevention and control.

Embodiment 2

[0041] Biological Assay Example 2, Indoor Toxicity Determination Test for Tomato Late Blight Compounded by Benthiopyram and Ningnanmycin

[0042] Test object: Tomato late blight pathogen

[0043] The potted method was used in this experiment. When the tomato pot grows to the stage of 2-4 true leaves, the number is reserved. Cultivate the pathogenic bacteria used in the test on a suitable medium. After the sporangia are produced, wash the sporangia with sterile water and filter them with double-layer gauze to make 1×10 5 sporangia / mL suspension. According to the drug activity, set 5-7 serial mass concentrations. Spray the liquid medicine evenly on the leaf surface until it is completely moistened, and wait for the liquid medicine to dry naturally for later use. For each treatment, 3 pots were repeated 4 times, and the treatment containing only solvent and surfactant but no active ingredient was set as a blank control. After 24 hours of chemical treatment, use a crop spraye...

Embodiment 3

[0055] Biological Assay Example 3, Indoor Toxicity Determination Test on Cucumber Powdery Mildew Bacteria Combined with Benthiopyram and Ningnanmycin

[0056] Test object: Cucumber powdery mildew

[0057] The potted method was used in this experiment. The potted plants grow to 4-5 true leaves, numbered for later use. The fresh spores of powdery mildew fungus produced on the leaves of the infected cucumber within 24 hours were evenly shaken off and inoculated on the cucumber seedlings to be tested. According to the drug activity, set 5-7 serial mass concentrations. After 24 hours of inoculation, spray the medicinal liquid evenly on the leaves until they are completely wet, and wait for the medicinal liquid to dry naturally for later use. For each treatment, 3 pots were repeated 4 times, and the treatment containing only solvent and surfactant but no active ingredient was set as a blank control. The inoculated test materials were moved to an artificial climate box (relative ...

Abstract

A sterilizing composition containing benthiavalicarb-isopropyl and ningnanmycin is disclosed. The composition includes the benthiavalicarb-isopropyl and the ningnanmycin, as effective components, in amass ratio of 50:1 to 1:50, with the balance being allowable and acceptable auxiliary components for pesticides. The composition can be prepared into suspension concentrates, wettable powder, water dispersible granules, microemulsion, emulsion in water, granules and suspension concentrates for seed dressing through known methods. The composition has obvious synergistic effects, can be used for controlling a plurality of plant diseases on vegetables, fruits and other crops, and is particularly suitable for controlling downy mildew, late blight and powdery mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing benthiazil and ningnanmycin and its application for preventing and controlling crop diseases, belonging to the technical field of pesticides. Background technique [0002] Benthiacarb, English name: Benthiavalicarb-isopropyl, chemical name: [[(6-fluorobenzothiazol-2-yl)-ethylcarbamoyl]-2-methylpropyl]carbamate isopropyl. Benthiopyram is a new type of fungicide jointly developed by Japan Combination Chemical Company and Ihara Company in 1992. Its active point is the substituted fluorine atom on the benzene ring and the amino acid peptide structure. This compound has high selectivity and is mainly effective for crops. Late blight and downy mildew caused by oomycetes have good preventive and therapeutic activities. [0003] Ningnanmycin, English name: Ningnanmycin, molecular formula: C 16 h 23 o 8 N 7 ,. Ningnanmycin is an innovative biopestic...
