Sclerotinia sclerotiorum can harm leaves, petioles and stems. The first leaf is usually diseased, with dark stains, and a dense layer of white mold on the surface when wet. Then spread downward causing petiole and stem disease. The affected part was brownish water-stained. When the speed was high, soft rot was formed. White mycelium grew on the surface. Finally, the stalk tissue rotted and hollowed out in the fibrous stem, forming rat urine-like black sclerotia. At present, it is conducive to the occurrence of the disease and must cause a high degree of attention to early detection, early prevention and control, and reduce losses. The law of incidence Ascospores are spread by wind and rain, invade the old leaves that are debilitating in their ability to live, and contact with diseased leaves and robust leaves and stems can spread mycelium. High temperature and humidity are conducive to the occurrence and epidemic of the disease. It is easy for celery to connect with fleas or cruciferous vegetables that are prone to sclerotinia. Poor drainage during the rainy season, with a heavy nitrogen fertilizer. Control methods 1. Agricultural control. Implement more than three years of rotation. Seed disinfection before sowing. During the rainy season, timely drainage will reduce the humidity in the field. The diseased leaves were removed from the fields in a timely manner, concentrated deep, and prevented from spreading. 2. Chemical control. At the beginning of onset, 70% thiophanate-methyl wettable powder 600 times, 50% carbendazim wettable powder 500 times, or 65% triamcinolone wettable powder 1000 times, spray once every 5-7 days Continuous prevention and treatment 2-3 times. The above pesticides are used alternately to avoid drug resistance.
