Key Management Points for Greenhouse Potatoes from Sowing to Planting Out
1. Use 75% thiophanate-methyl at 600-800 times dilution or 75% chlorothalonil at 1000 times dilution to control damping-off; spray the seedbed with 72.2% propamocarb aqueous solution at 5-7.5 ml per sq m to control Pythium damping-off, which also controls early blight, anthracnose, and other diseases. 2. During the seedbed stage, spray per 667 sq m with two bags of Wu's chili pepper powder, or 500-800 times dilution of kebingling, or 400 times dilution of virus A wettable powder to control viral diseases. Spray once every 7 days, for 3 consecutive sprays. All can achieve good results.
