[0025] Biological Assay Example 1: Indoor Toxicity Determination of Compositions to Cucumber Downy Mildew

[0026] Test object: Cucumber downy mildew (collected from the field)

[0027] Test method: The flat plate leaf method was used to determine the indoor toxicity of the combination of oxafecondone, disenlian and benzin against cucumber downy mildew. Select disease-free cucumber leaves with the same leaf position, 10 pieces per treatment, soak in the medicinal solution of each treatment, take out and dry after fully infiltrating, and put them in a petri dish covered with moisturizing paper. After 24 hours, the fresh sporangia suspension of cucumber downy mildew fungus (Pseudoperonospora. cubensis) was evenly sprayed on the entire leaf surface. The preparation process of the sporangia suspension of cucumber downy mildew fungus is as follows: take fresh cucumber downy mildew leaves with typical symptoms, moisten and cultivate them at about 18°C ​​for one day to promote the f...

[0053] Biological Assay Example 2: Indoor Toxicity Determination of Compositions against Cucumber Powdery Mildew

[0054]Test object: Cucumber powdery mildew (collected from the field)

[0055] Test method: Select two cucumber seedlings at the true leaf stage in pots with the same growth potential, and use 5 pots for each treatment, numbered for future use. The powdery mildew diseased leaves of cucumber collected from the field were evenly shaken off the conidia above the cucumber seedlings for inoculation, and treated with chemicals 24 hours later. See Table 3 and Table 4 for the test chemicals. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot. Five concentration gradients were set for each drug. The cucumber seedlings sprayed with the same amount of water were used as the blank control. After the spraying treatment, the cucumber seedlings were cultivated in the greenhouse. After 7 days, according to the incidence grading standard of cucumber powdery mi...

Abstract

The invention relates to a sterilizing composite. The active ingredients are (A) famoxadone and (B) one of zineb, amobam, propineb, polyram, thiram and chlorothalonil, wherein the mass ratio of (A) to (B) is 50:1-1:50. The sterilizing composite can be prepared into wettable powder and water dispersing granules by a known method. The sterilizing composite has an obvious synergistic action and can be used for controlling diseases of crops such as vegetables, melons and fruits, grains and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing oxafeconone. Background technique [0002] In recent years, due to monotherapy and other unscientific medication methods, pathogenic fungi such as powdery mildew, rust, downy mildew, leaf spot, and scab have developed resistance to some commonly used agents, and have become the mainstay of chemical control. A big problem. 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. If some highly effective new 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 a new fungicidal composition with synergistic effect, low cost and environmenta...
