Prevention and cure method of celery soft rot
1. Rotation. Celery soft rot spreads mainly through soils, etc. It is easy to accumulate a large number of germs in the soil of heavily populated land, and it is easy to become sick and aggravate the condition. Therefore, more than two years of rotation should be implemented.
2. Cultivation management. Because the soft rot pathogen first invades from the wound of the plant, the plant wound is one of the important factors of the disease. In the process of planting, cultivating, weeding and other operations, we should avoid injuring the roots or causing the plants to cause wounds. In time, spraying new high-fat membranes can prevent invasion of pathogens. Planting should not be too deep, soil should not be too high, so as to avoid the petiole embedded in the soil; timely drainage after the rain; found diseased plants in time to remove, and sprinkled lime and other disinfection; the onset of reduced or stopped watering to prevent flooding irrigation.
3. timely pest control. Insects can also cause wounds on plants, leading to morbidity. Therefore, pest control should be timely.
4. Chemical control. At the beginning of the disease, spraying the new high-fat film 500 times solution with 72% of agricultural streptomycin sulfate soluble powder or neomycineomycin 3000-4000 times solution or 14% metham ammonium water solution 350 times or 50% ampicillin fertilizer acid Copper wettable powder 500-600 times, spraying once every 7-10 days, continuous spray 3-5 times.
