Pay attention to flood control vegetable diseases in the rainy season
Leek disease is an important disease in the current production of leeks. The disease occurs in all parts of the country, especially in severe rainy seasons, and can result in a direct reduction of production by 30% to 40%. In addition, the disease can also harm onions, onions, garlic and other vegetables. I. Symptoms Symptoms After the leaves and buds of leeks are affected, many dark brown spots begin to appear on the lower part of the leeches and gradually expand upward to half of the leaves and buds. The diseased part of the disease contracted after dehydration, and the leaf blade and calyx drooping above the contraction rotted. When the air is wet, sparse white mould grows on the affected area. The pseudo-stem suffers from water-stained, light-brown, soft rot that grows gray and mold, and the leaf sheath is easily shed. The damage to the bulbs caused light brown or dark brown rot in the root plate, and pale brown in the internal tissues. The roots were rotted brown with few root hairs. Second, the incidence of law Pathogens: The leek disease is a fungal disease that is caused by the infestation of P. infestans. The oocysts were overwintering in the soil with the diseased plant residues and became the first source of infection in the second year. 2. Mode of transmission: The germs were initially infested by sporangia and oospore germination, and the diseased parts produced sporangia under wet conditions. They spread through wind and rain, repeated infections, and caused disease epidemics. 3. Incidence conditions: The optimum temperature for field disease is 25°C to 32°C, high humidity, and heavy onset. Generally, the rainy season is long, the rainfall is large, the temperature is high, the terrain is low, and the rain is ravaged. The ventilation of the protection area is not timely or the time is not enough. Over-close planting or partial application of nitrogenous fertilizer is easy to cause. Third, control methods 1. Strengthen cultivation and management: arrange 3 to 4 years of dumping to avoid continuous cropping for a long time; after harvest, remove and destroy the diseased body to prevent the spread of germs; keep leeks and rakes clean, refurbish irrigation and drainage system, facilitate drainage and prevent flooding to avoid excessive application of nitrogen fertilizer, and diligently cultivating; Protected areas to take timely measures such as air release, so that the sporangia is not easy to germinate, thereby reducing the accumulation of pathogens and reduce the incidence. 2. Chemical control: Spray 70% mancozeb 500 times before the onset of disease prevention and use the following agents to spray at the beginning of the disease: 64% imported antivirus (produced by Swiss Syngenta company) WP 500 times, 72.2 % Precizer (Germany Bayer) 800 times, 69% decanoyl morpholine Mn-Zn wettable powder 800 times, 75% chlorothalonil wettable powder 600 times, 58% metalaxyl Manganese bell WP 500 times, 50% methicone wettable powder 600 times and so on. Spray once every 7-10 days and spray 2 or 3 times. (Yongqing County Vegetable Management Bureau, 065600)
