Rust occurs frequently in vegetables. Broad bean rust is a highly susceptible disease, mainly harmful to leaves and stems. The prevention methods are as follows: 1. Sowing at the right time to prevent the incidence of pre-winter, reduce the number of pathogens, and avoid the rust period during the late growth period. 2. Use early maturing varieties to harvest when the rust is large before harvest or near maturity. 3. Reasonable close planting, ditching drainage, timely pruning, reducing field humidity. 4. Do not plant summer broad bean or early broad bean, reduce the source of winter and spring bacteria; water washing during winter sowing can also reduce the incidence. 5. Start spraying 30% solid stone sulphur 150 times solution or 15% triazolone wettable powder 1000-1500 times solution, 25% tebuconazole 1500 times solution, 50% sulfur suspension agent 200 times solution, 25% Enemy de-emulsion 3000 times liquid, 25% enemy de-emulsion 4000 times liquid plus 15% triazolone wettable powder 2000 times liquid, once every 10 days or so, continuous control 2 to 3 times. Once the rust is prevented, it can be difficult to prevent it. It can be treated with a proper amount of pesticide bactericide before sowing. It can also be used to disinfect the soil with 1000 times of the carbendazim or the carbamide, and to prevent the disease in advance.
