example 1

[0023] Bioassay Example 1: Indoor Toxicity Determination of Shenzimycin, Thiophanate-Methyl and Carbendazim to Rice Sheath Blight

[0024] Test object: Rice sheath blight (Rhizoctonia solani), collected from the field, separated and purified indoors.

[0025] Test method: Refer to "People's Republic of China Agricultural Industry Standard NY / T1156.5-2006", adopt broad bean leaf method. Choose susceptible faba bean potted plants, cut leaves with petioles in the same part, with the same growth, keep them moisturized, and place them in a petri dish. Dissolve the original drug with acetone, dilute with 0.1% Tween 80 water, and prepare 6 series of mass concentrations. Fully soak the leaves in the pre-configured medicinal solution for 5 seconds, drain off the excess medicinal solution, and after natural air-drying, use an inoculator to inoculate the side of the bacterium cake with a diameter of 5mm and the mycelium in the center of the treated leaves, and inoculate 30 leaves for ea...

[0036] Bioassay Example 2: Indoor Toxicity Determination of Shenzimycin and Benomyl Compound to Cucumber Blight

[0037] Test object: Cucumis sativus L., collected from the field, separated and purified indoors.

[0038] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. Dissolve the original drug with acetone, dilute with 0.1% Tween 80 water, and prepare 6 series of mass concentrations. Under sterile conditions, take 5 mL of the prepared medicinal solution and mix them with 75 mL of culture medium evenly to make 4 plates containing medicine, and mix an equal amount of sterile water with the culture medium as a control. Under aseptic conditions, the cultured cucumber blight was cut out from the edge with a sterilized puncher with a diameter of 5 mm. Use an inoculator to inoculate the fungus cake on the center of the drug-containing plate, with the mycelium facing down, and place it in a 25°C incubat...

[0047] Bioassay Example 3: Indoor Toxicity Test of Shenzimycin, Thiabendazole and Prochloraz on Watermelon Fusarium Wilt

[0048] Test object: watermelon wilt (Fusarium oxysporum f.sp. Niveum, FON), collected from the field, separated and purified indoors.

[0049] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. The test method and statistical method are the same as the biological assay example 2, and the toxicity assay results are shown in Tables 4 and 5.

Abstract

The invention relates to a plant disease control composition containing phenazino-1-carboxylic acid. Effective constituents are the phenazino-1-carboxylic acid (A) and one of thiophanate-methyl, carbendazim, benomyl, thiabendazole and prochloraz (B). The proportion of the constituents (A) and (B) is 50:1-1:50. The composition can be made to a suspending agent, wettable powder, seed coating, emulsion in water, microemulsion, missible oil, granules and water dispersible granule. The composition is used for preventing and treating one or more diseases of cucurbitaceous vegetables, field crops and fruit tree crops.

Description

technical field [0001] The present invention relates to a kind of plant disease prevention and control composition, especially one (B) compound of Shenzimycin (A) and thiophanate-methyl, carbendazim, benomyl, thiabendazole and prochloraz With composition. Background technique [0002] The high-density and high-intensity farming mode meets the society's demand for agricultural food and creates considerable economic value. Under this cropping system, chemical agents are necessary measures to control the increasingly serious pests and diseases, and play an extremely important role in ensuring normal agricultural production. A new compound will initially show excellent effects, but after long-term and single use, it will gradually lose its activity, especially systemic antibiotic fungicides are more likely to induce resistance of pathogenic bacteria. [0003] Shenzimycin is a fermentation product of Pseudomonas fluorescens M18, the main component is phenazine-1-carboxylic acid...
