The rich tree trunk has mildew spots, no matter what the reason, it is unsightly. Therefore, it is necessary to prevent and cure as soon as possible.

The mildew spot on the trunk of the rich tree is estimated to be related to root rot.

Root rot is a common disease that seriously harms rich trees, also known as rot.

In this regard, we might as well first see if the trunk is still hard. If it is still hard, it means that the rich tree can still grow normally. Otherwise, the trunk will die and there will be no cure.

Prevention and control methods:

(1) keep the cultivation environment dry and attach importance to the disinfection of cultivation media and sites.

(2) after the semi-finished products are unloaded into the operation shed, the head of the wealth tree is sprayed with Sukeling to prevent the harm of Botrytis cinerea.

(3) cut off the sprained and rotten tissue at the top of the main root with a sharp knife before planting, then spray the wound with Sukeling, and plant it after drying.

(4) after a week of planting, the medium in the basin dries gradually, the healing tissue has been formed, and the new root has begun to grow. It is advisable to spray the smooth rod of the wealth tree with pluck, Anke or zinc and manganese (Redomir-manganese zinc) to flow into the basin soil along the pole. Since then, fungicides have been rotated once a week with Anke, carbendazim, Redomir or carbendazim.

(5) if Pythium is active, it should be sprayed with Pulek, carbendazim, Redomir or Phytophthorin, and the general effect is about two weeks. If the weather is still bad, different chemicals should be sprayed to prevent the development of drug resistance. If festering plants are found during this period, they should be discarded immediately.

Therefore, we must master the growth habits of the wealth tree, control the water, nutrients, sunshine, and so on, in order to make the wealth tree thrive.
