During ginger cultivation, the following pests and diseases need to be controlled:
Stem diseases (ginger blast, ginger rot, etc.); when diseased plants are found in the field, promptly dig out the diseased plants and the soil around them, carry them out of the field for deep burial, apply 125 grams of bleaching powder in the hole or pour 1% bleaching powder solution, then seal the mound with sterile soil. The control effect is good.
Leaf diseases (ginger anthracnose, leaf blight, etc.): when diseased leaves are found in the field, promptly pick them off and place them in plastic bags, carry them out of the field to burn or bury deeply. At the same time, as early as possible, use 70% thiophanate-methyl wettable powder at 1000 times solution plus 75% chlorothalonil wettable powder at 600-700 times solution for foliar spraying control, once every 7-10 days, for 2 consecutive sprays. Be careful to spray evenly and finely. Stop using the chemicals 20 days before harvest.
Ginger borers and aphids: when ginger borers and aphids are found in the field, promptly spray Yangkang No. 3 suspension concentrate (Grade AA green food production material) at 750 times solution or use abamectin preparation (1.8% Miechongling) at 6000 times solution for control, and appropriately change the dosage according to the size of the ginger growth and the pest situation. At the same time, turn on high-pressure mercury lamps at night to trap and kill adult insects.
