Embodiment 1

[0079] To determine the virulence of copper thiazide and metalaxyl mixed in proportion to the pathogen of cucumber downy mildew, the test object was cucumber downy mildew, and repeated 4 times. The test results showed that the mixed pair of thiadiazepine copper and metalaxyl had an obvious synergistic effect on the activity of cucumber downy mildew, and the ratio of thiadiazepine and metalaxyl was between 5-40:1-60 when used alone in the same ratio. It has high activity, more preferably 10-40:2-60, especially at 30:45, it has obvious synergistic effect. The mixed use can also reduce the usage of both. See Table 1.

Embodiment 2

[0084] To determine the virulence of thiazolium copper and dipropystrobin in proportion to the ginger blast fungus, the test object is the ginger blast fungus, repeat 4 times. The test results showed that the mixed pair of thiamethoxam and dipropynyl had an obvious synergistic effect on the activity of ginger blast fungus: the ratio of thiadimethoxen and dipropynyl was between 5-40:1-60 under the same ratio alone. The use of the sum has high activity. More preferably, the ratio is 10-40:2-60, especially at 32:45, which has obvious synergistic effect. The mixed use can also reduce the amount of both. See Table 2.

Embodiment 3

[0088] The virulence of thiazide copper and fluopyram were mixed in proportion to the pathogen of bacterial angular leaf spot of cucumber. The test object was pathogen of bacterial angular leaf spot of cucumber, repeated 4 times. The test results show that: the mixed pair of thiazolin and fluopyram has an obvious synergistic effect on the activity of Cucumber bacterial angular leaf spot disease. The ratio of thiazolin and fluopyram is between 5-40:1-60 under the same ratio. The combined use alone has high activity. More preferably, the ratio is 10-40:2-60, especially at 24:43, which has a significant synergistic effect. The mixed use can also reduce the amount of both. See Table 3.

Abstract

The invention relates to the field of pesticides, and particularly relates to a compound fungicide containing thiediazole copper. The compound fungicide is characterized by comprising active components and an auxiliary component, wherein the active components comprise thiediazole copper A and a sterilizing active compound B; the sterilizing active compound B is any one of sterilizing active compounds of a triazole fungicide, a carboxylic acid amide fungicide, an imidazole fungicide, a dicarboximide fungicide, a carbamate fungicide, an antimicrobial fungicide, an oxazole fungicide, a pyrimidine bactericide, a quinoline fungicide, a dithiocarbamate salt fungicide, a morpholine fungicide or other selected bactericides. According to the compound fungicide disclosed by the invention, the problem that the sterilizing active compound cannot meet the overall requirements of comprehensive control in plant resistance and activity is solved, and bacteriosis and fungal disease can be comprehensively prevented and treated. The auxiliary component also comprises an additive, so that the fungicide disclosed by the invention is long in effective drug duration and few in application frequency, and the disease prevention and control processes of crops are effectively regulated.

Description

Technical field [0001] The present invention relates to the field of pesticides, in particular to a compound fungicide containing thiazolium copper. Background technique [0002] In today's agricultural field, due to single medication and other unscientific medication methods, some bacterial and fungal diseases have become resistant to many drugs, which has become a major problem in the agricultural sterilization process. Due to the resistance of pathogens, farmers' frequent application of pesticides has resulted in increased drug costs and increased environmental pollution. Some high-efficiency new medicines, if used alone for a long time, also face the risk of drug resistance. In addition, the newly developed medicines are difficult to promote and apply in the market due to their high prices. Therefore, it is an urgent problem for those skilled in the art to find a novel bactericidal composition with high efficiency, broad bactericidal spectrum, low cost and environmental prot...
