Infection with ginger blast is difficult to cure. How to control ginger blast?

Ginger blast is a soil-borne disease, which is easy to occur in the expansion period of ginger, resulting in plant death and rapid spread. Ginger blast should be based on prevention. Once infected, it is difficult to control and cure. The following measures can be taken to control ginger blast.

Ginger blast

First, ginger seed disinfection. Before planting, the ginger seeds were soaked in 600 times more than 80% carbendazim aqueous solution for 3 hours, picked up, dried, and then planted to kill the bacteria attached to the ginger seeds.

Second, soil disinfection. In the land where ginger is grown, when digging holes before planting, use 600 times 80% sodium sulfoxide aqueous solution to sprinkle the soil in the planting holes. It is about 1.5 kilograms of 1ml per hole. When cultivating soil to cover ginger seeds after planting, the covered soil was sprayed with 1000 times 80% zinc solution. To kill germs attached to the soil.

Third, the liquid medicine is infused into the root. After the ginger seedlings were exposed to the soil, the roots of ginger seedlings were irrigated with 600 times 50% pentachloronitrobenzene for about 2 kg per plant, which was evenly irrigated in the soil around the roots of ginger seedlings.

Fourth, apply biological bacterial fertilizer. Combined with soil cultivation and fertilization, biological bacterial fertilizer was added at the same time. Apply about 50 grams of ginger each time. It can improve the resistance of plants to ginger blast and effectively inhibit the occurrence and damage of ginger blast.

Fifth, foliar spraying, foliar topdressing. In the process of ginger growth and development, the old disease area was foliar sprayed once every 15 Murray for 20 days. Use 1000 times 0.5% dimethyl disulfide, 1000 times 80% mancozeb, 1000 times natural brassin, 1000 times amino acid sugar phospholipid mixture, etc., spray all stems and leaves of ginger evenly until water drops begin to drop. It can not only kill insects and prevent disease, but also supplement nutrition and enhance the disease resistance of ginger plants.
