Diseases: The main diseases occurring during seedling stage are black rot and downy mildew. The seed is treated by mixing the seedlings with warm soup and soaking the seeds. The seeds are placed in 50 ° C warm water for 10 minutes, and then the seeds are mixed with 50% thiram or 75% chlorothalonil with a seed weight of 0.4%. The field where the downy mildew disease occurs in the seedling stage can be controlled by spraying with 58% metalaxyl and mancozeb 600 times.
Pests: The pests that are harmful to cabbage in the seedling stage are mainly beet armyworm, Spodoptera litura, and alfalfa. Where conditions permit, seedlings can be covered with insect-proof nets to prevent pests from entering the hazard. The pests were found to be 2-3 times with a high (8% fluridazine urea high emulsifiable concentrate) 1500 times solution or 10% divided by 2000 times liquid spray. Use 1200 days before transplanting to get your medicine.
Grass damage: Soil treatment before sowing is an important measure to effectively prevent seedling damage. Generally, after sowing the cover soil, use 150% 200-200 ml of dichlorpyrifn per acre, or 60-80 ml of 33% applied fertilizer, or 40-50 ml of 96% Jinduer, and spray with 50 kg of water to prevent it.
