[0034] Bioassay Example 1: Indoor Toxicity Determination of Benhexamid and Hexaconazole or Fluquinazole to Wheat Powdery Mildew

[0035] Test object: Wheat powdery mildew bacteria collected from the field

[0036] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.4-2006". Wheat powdery mildew diseased leaves collected from the field were evenly shaken off the conidia above the wheat seedlings for inoculation, and 24 hours later, they were treated with chemicals. See Tables 1 and 2 for the test chemicals. Select wheat seedlings at the three-to-four-leaf stage with consistent growth potential, and select 3 pots of wheat seedlings for each treatment, and spray them with a Potter spray tower at a pressure of 50PSI, about 5mL per pot. Five concentration gradients were set for each drug. The same amount of water was sprayed as the blank control. After spraying, the wheat seedlings were put into the greenhouse for cultivation. After 7 days,...

[0044] Biological Assay Example 2: Indoor Toxicity Determination of Botrytis cinerea against Cucumber Botrytis Cinerea with Difenoconazole

[0045] Test object: Cucumber Botrytis cinerea collected from the field

[0046] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. Cucumber Botrytis cinerea was cultivated with PDA medium. When the bacterial colony was just overgrown with the petri dish, a puncher with an inner diameter of 7 mm was punched from the edge, and the resulting mycelium block was used as an inoculum. Take 5 mL of the prepared drug solution and mix them with quantitative 75 mL of sterilized medium to make 4 drug-containing plates, and use the same amount of sterile water mixed with the medium as a control. Put the hyphae upside down and connect them to the center of the plate, and culture them in a 28°C incubator. After 7 days, the colony diameter was measured by the cross method, and t...

Abstract

The invention relates to a sterilization composition which comprises the effective ingredients of one of (A) zoxamide and (B) triazole compounds, wherein the triazole compounds are selected from tebuconazole, hexaconazole, difenoconazole, epoxiconazole, flusilazole, myclobutanil, penconazole, fluquinconazole, diniconazole, triazolone, propiconazole, triadimenol, flutriafol, bitertanol and cyproconazole, the mass ratio between A and B is 50:1-1:50, and the balance is auxiliary ingredients that are allowable and acceptable in pesticides. The sterilization composition can be used for preparing wettable powders, missible oils, suspending agents, water dispersible granules, emulsion in water and microemulsion by adopting known methods. The zoxamide has remarkable synergic effect after being compounded with any one selected triazole compound according to a certain proportions; and the sterilization composition can be used for preventing and treating diseases on crops, such as grains, vegetables, fruit trees, and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing benzamid and triazole compounds. Background technique [0002] In recent years, due to single drug use and other unscientific drug use methods, many pathogenic bacteria such as powdery mildew, gray mold, and downy mildew have developed resistance to many currently used pesticides, which has become a major problem in chemical control. Due to the resistance of the bacteria, the frequent application of pesticides by farmers has resulted in increased cost of pesticides and aggravated environmental pollution. However, if some currently effective drugs are used alone for a long time, they also face the risk of drug resistance. In addition, due to the high price of newly developed drugs, it is difficult to fully promote and apply them in the market. Therefore, it is necessary to find synergistic, low-cost and environmentally friendly fungicide...
