Embodiment

[0031] Embodiment: Fungicide is to the growth inhibitory effect of banana fusarium wilt bacterial strain Fusarium oxysporum Cuba specialization type (Fusariumoxysporum f.sp.cubense) No. 4 physiological races

[0032] Compounds 1-4 of the present invention were ordered from Shenyang Sandu Pharmaceutical Technology Co., Ltd. Bacillus amyloliquefaciens G9R-3 was prepared and preserved by the inventor's laboratory.

[0033] Antibacterial experiments were carried out using conventional methods in the art. Briefly, after the Foc4 of Fusarium oxysporum was activated on the plate, it was cultured on a PDA plate at 28°C for 3 days, and a fungus cake with a diameter of 5 mm was punched at the edge of the colony with a puncher for use. Add fungicides respectively in the 50mL PDA after melting, pour it into the petri dish (90mm) and make the poisoned plate, inoculate the Foc4 bacterium cake after cooling the plate, inoculate the Foc4 bacterium cake with the non-toxic PDA plate as the bla...

Abstract

The invention provides a plant fungicide containing aminotriazole compounds for preventing and treating banana wilt. The aminotriazole compounds provided by the invention have the effect of inhibiting the plant pathogenic fungus Fusarium oxysporum f.sp. cubic (Fusarium oxysporum f.sp.cubense), and are used in the prevention and treatment of banana wilt caused by Fusarium oxysporum f.sp.cubense. has some potential. In addition, the present invention also provides a plant fungicide comprising an aminotriazole compound and Bacillus amyloliquefaciens, which has a synergistic effect in preventing and treating banana wilt caused by Fusarium oxysporum cuba-specific.

Description

technical field [0001] The invention provides a plant fungicide containing aminotriazole compounds for preventing and treating banana wilt. Background technique [0002] Banana Fusarium wilt, also known as Panama disease and yellow leaf disease, is a devastating banana fungal disease caused by Fusarium oxysporum f.sp.cubense (Foc). Soilborne diseases. Banana Fusarium wilt involves 4 physiological races, of which race 4 (FOC4) infects almost all the main varieties of bananas grown in my country, and has a great impact on banana production in my country. The disease has a wide transmission route, strong pathogenicity, rapid spread, high infection rate, difficult control, high mortality of infected plants, and is called "banana cancer". Once the banana wilt occurs, it will be extremely destructive and will seriously harm the banana industry. The disease was discovered in Australia in 1874, and it broke out in Panama and several countries in South America in the middle of the...
