[0031] Biological Assay Example 1: Indoor Toxicity Determination of the Combination of Benhexamid and Zinc on Grape Downy Mildew

[0032] Test object: Grape downy mildew collected from the field

[0033] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.7-2006", pot method. Use a brush to dip distilled water at about 10°C to wash the sporangia collected from the back of grape leaves with downy mildew in the field, and make 3×10 5 sporangia / mL suspension. Select two grape seedlings at the true leaf stage with the same growth, and select 5 pots of grape 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 agent, and the same amount of water sprayed was used as the blank control. Spray and inoculate grape downy mildew 24 hours after the chemical treatment. After inoculation, put the grape seedlings in an artificial climate box (100...

[0045] Biological Assay Example 2: Indoor Toxicity Determination of the Combination of Benhexamid and Propineb against P. infestans

[0046] Test object: Pseudomonas infestans collected from the field

[0047] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. Cultivate P. infestans infestans with PDA medium. When the colonies just cover the petri dish, use a puncher with an inner diameter of 7 mm to punch holes from the edge, and the punched mycelium blocks are used as 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 the net mycelial growth and mycelial...

[0055] Bioassay Example 3: Indoor Toxicity Determination of Botrytis cinerea against Cucumber Botrytis in combination with benzamide and mancozeb

[0056] Test object: Cucumber Botrytis cinerea collected from the field

[0057] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. The test and statistical methods are the same as those in the biological assay example 2. The results of the toxicity test are shown in Table 3.

[0058] The test results showed that benzamid and mancozeb had a significant synergistic effect on cucumber Botrytis cinerea at a ratio of 50:1 to 1:50, especially at a ratio of 10:1 to 1:20. The synergistic effect is more obvious, and the co-toxicity coefficient is above 165.

Abstract

The invention relates to a pesticide composition which contains the active ingredient being compound composition of benzoyl bacteria amine and any of dyson fungicides which have the mass proportion of50:1-1:50 with better proportion of 10:1-1:20, and the rest components are auxiliary elements that are allowed to be used in pesticide and can be accepted. The dyson fungicides are selected from zineb, maneb, amobam, mancozeb, propineb, polyram, etc. As the benzoyl bacteria amine is compounded with any of the dyson fungicides according to a certain proportion, the pesticide composition has remarkable synergistic effect and can be used for controlling diseases of multiple plants such as vegetables, fruit trees, grain, ornamental plants, etc.

Description

technical field [0001] The invention relates to a pesticide composition, especially a compound composition containing dyson fungicides. Background technique [0002] In the actual process of agricultural production, chemical control is the main effective means of disease control. However, due to single and unscientific drug use in recent years, many pathogenic bacteria have developed resistance to the currently used pesticides, such as powdery mildew, gray mold, and downy mildew, which are very common and have become a major problem in chemical control . Due to the resistance of the bacteria, the frequent application of pesticides by farmers has increased the burden and environmental pollution. Therefore, there is an urgent need for new varieties of fungicides with high efficiency, safety and environmental protection. [0003] Zoxamide is a highly effective protective amide fungicide with long-lasting effect and good resistance to rain erosion. Its mechanism of action is ...
