Embodiment 1
[0113] Embodiment 1 control cucumber downy mildew test
[0114] The potted cucumber seedlings at the two-leaf stage of "Shandong Mici" were sprayed with an aqueous solution (concentration as described below) of the active component. After 24 hours, the cucumber downy mildew spore suspension was inoculated on the cucumber leaves, and then placed Cultivate in a climate chamber with a temperature of 18±1° C. and a relative humidity of 90±5%, and measure the development degree of pathogen infection on the leaves after 3 days. See Table 1 and Table 2 for the activity data results of each individual active component and the composition of the present invention on cucumber downy mildew.
[0115] The results show that the actual control effect values of the composition are greater than the theoretical control effect values, and the composition exhibits a synergistic effect within the range of the test proportion.

Embodiment 2
[0123] Example 2 Control of Cucumber Powdery Mildew Test
[0124] Potted cucumber seedlings (variety: Xintaimici) with uniform growth and the same leaf age were selected, and sprayed on the crop sprayer according to the designed dosage, and a blank control without pesticide was set up. After 24 hours, the pathogenic bacteria were inoculated, and then moved to the greenhouse for normal management. The culture conditions (temperature: 23-28°C during the day and 18-20°C at night) were cultivated for 8 days before the results were investigated. Investigate the degree of development of the fungal infestation on each leaf. See Table 3 and Table 4 for the activity data results of each individual active component and the composition of the present invention for controlling cucumber powdery mildew.
[0125] The results show that the actual control effects of the compositions are greater than the theoretical control effects, and the compositions show a synergistic effect within the tes...

Abstract
The invention discloses a fungicide and a composition thereof, which comprises compound A as a single agent or a compound of compound A and other fungicide active ingredients, and the compounding weight ratio of compound A and other fungicide is 1:100-100:1 . In the present invention, compound A is used as a single agent or compound A and other fungicides are compounded in two or three components, so that the obtained single agent or composition has excellent control effect. At the same time, the composition expands the bactericidal spectrum and has a synergistic effect. In the present invention, compound A is applied to fungicides and compounded with other fungicide active ingredients, which can improve the effect of disease prevention and control, and make it difficult for bacteria to develop drug resistance. It can be used to prevent and control vegetables such as cucumbers, cabbage, spinach, peppers, tomatoes, etc., and Downy mildew, late blight, blight, damping-off, powdery mildew, rust, anthracnose, etc. on crops such as potatoes, grapes, citrus, and bananas, as well as soybean root rot, tobacco leaf blackleg, etc.
Description
technical field [0001] The invention belongs to the field of agricultural fungicides, and in particular relates to a fungicide and a composition thereof. Background technique [0002] Downy mildew, powdery mildew and blight are common and frequently-occurring diseases of melons, fruit trees, vegetables and other crops, which seriously affect the yield and quality of products and often become devastating diseases. [0003] Downy mildew is a plant disease caused by downy mildew in fungi. Downy mildew can occur at all stages from seedlings to harvest, and the adult plants suffer the most. It mainly damages the leaves and develops from the base to the upper leaves. In the early stage of the disease, light yellow sub-circular to polygonal lesions are formed on the leaves. When the air is humid, a frosty mold layer is formed on the back of the leaves, and sometimes it can spread to the leaves. In the later stage, the disease spots are withered and contiguous, and they are yello...
