Common diseases and prevention methods of ground rooting

Common diseases of ground rooting: Botrytis cinerea

The seedlings infected with gray mold are light in color, and the leaves and petioles are grayish white and water-soaked. The tissues soften and rot, and gray mold grows on the surface when the humidity is high.

Young stems often initially develop irregular water-soaked spots at the base of the petiole, which quickly become soft and rotten, and then shrink or break. Finally, the diseased seedlings rot, wither and die.

Prevention and control methods: Manually cut off diseased leaves or apply pesticides. The agent can be sprayed with 1000 times diluted 70% methyl thiophanate wettable powder.

Common diseases of ground rooting: powdery mildew

Powdery mildew mainly harms wheat leaves, but also stems and ears. Small yellow spots begin to appear on the leaves, then expand into round or oval spots with a white powdery mold layer on the surface. Generally, there are more leaves on the bottom than on the top, and more leaves on the back than on the front.
