Bohu County has a long history of planting and processing tomatoes. The annual planting area accounts for 30-40% of the medium-upper arable land. The tomato plague is serious and the degree of disease damage is increasing year by year, which greatly affects the yield and quality of tomatoes.
Symptoms: Seedlings suffer from damage, resulting in water-stained dark green lesions on the stem base. One week after the stem, the diseased part curled into a thin line, the seedlings fell down and died, but the cotyledons remained green, causing serious dead seedlings and even seed destruction.
Pathogen: Fungal disease caused by Pythium infestans
Transmission routes and onset conditions: The bacteria can survive for a long time in soils rich in organic matter. The pathogens use oospore in the soil or the mycelium to overwinter on the sickness. Germs spread through soil and seeds. The temperature is low, humidity is high, or the incidence of pathogenic bacteria and soil carriers is heavy.
Control methods: Control by soil treatment and seed treatment. 0.3% Dixon was used for seed dressing; in the early stage of disease, 70% mancozeb Zinc wettable powder 50g plus potassium dihydrogen phosphate and dicalgin 20g against 15kg water spray were used. To reduce soil moisture, a thin layer of dry soil or ash can be sprinkled on the bed soil.
