Description

(1) Technical field [0001] The invention belongs to the field of pesticides and relates to a fungicide composition. (2) Background technology [0002] Wheat rust, including wheat stripe rust, leaf rust and stem rust, is a type of disease that occurs widely and causes the most serious damage to wheat in my country. In my country, the three rust fungi are all infected by uredia spores on wheat-based wheat crops generation by generation and complete the annual cycle, and they are typical distant airborne diseases. When the uredia spores fall on the leaves of the host and germinate under the conditions of appropriate temperature (stripe rust 1.4-17°C, leaf rust 2-32°C, stem rust 3-31°C) and a water film, germ tubes are formed along the leaf surface. Growth, the top of the stomatal germ tube expands to form appresses, and then invades the stomata, forms a substomatal pouch under the stomata and grows several infected hyphae, spreads in the space between the mesophyll cells and p...

Problems solved by technology

[0003] At present, the pesticides used in the field for preventing and treating wheat rust include 15% fenxining WP, 20% fenxining EC, 12.5% ​​Subaoli wettable powder, etc. The control effect is always unsatisfactory. Due to long-term frequent or unscientific use of these pesticides , so that the resistance of wheat rust is serious, and the amount of application increases, which leads to the increase of control cost, which is not ideal
