Disease prevention and control of ginseng fruit

Disease type

Leaf mold

Speaking of leaf mold, it usually harms the leaves of ginseng fruit. This disease first occurs on the leaves. White mold will appear on the back of the leaves. The leaves will gradually turn yellow and then curl. This phenomenon will start from the leaves at the bottom and spread upwards, causing a large area of ​​leaves to fall, greatly affecting the growth of the fruit.

Cotton blight

Blight is a disease that seriously affects fruit development, usually with light brown spots growing on the top of the fruit. White mold-like substances will gradually grow on the surface. This fungus will gradually corrode the inside of the fruit. After a humid rainy season, the diseased fruit will fall off from the neck, causing a large-scale reduction in fruit yield, which is extremely harmful.

Governance

When it comes to disease prevention and control, you can plant disease-resistant tree species. The seeds contain disease-resistant genes and only need to be slightly disinfected before sowing. Planting this tree species is beneficial to the prevention and control of fruit diseases and can effectively reduce the infection of fruit blight, which is a relatively good control method.

Another method is to strengthen the management of planting soil, select disease-free and insect-free seedlings for cultivation and propagation, clean the potting soil of the cultivated seedlings to avoid the growth of weeds and infection by diseases and insects. In addition, always pay attention to the condition of the seedlings and remove any diseased seedlings. When pruning the branches, keep the healthy branches and leaves, remove the weaker branches and buds, and spray pesticides appropriately to ensure the control of bacteria so that the ginseng fruit can grow normally.
