First, the blight is mainly harmful in the seedling stage, causing the plant to wither. The ventilation is poor and the disease is serious when there is stagnant water in the field.

Second, aphids occur in early summer. The sap is absorbed from the tender leaves, stems and buds, which makes the plants wither and grow poorly. Control methods: (1) clean the countryside, eradicate weeds in the field, and reduce the overwintering insect population; (2) during the occurrence period, spray 1000-2000 times of 50% fenitrothion or 1500 times of dichlorvos EC every 7-10 days for several times in a row.
