Also, benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated (cells have normal features).Benign tumors are typically surrounded by an outer surface (fibrous sheath of connective tissue) or remain with the epithelium.lso, benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated (cells have normal features).
Instructions. Cut off any unwanted suckers or shoots that are growing from the root system using a sharp spade. Remove the sucker, then cut and gouge the remaining underground bud with the spade.If the internal bud is not killed, the sucker will regrow. Too many of these shoots can crowd plants and reduce productivity. Banana trees are somewhat sensitive to frost, which can cause roots to freeze. 2  Do not apply herbicide to tree roots of plants that you wish to retain, as the chemicals can seep into other parts of the banana.
Mechanical Removal. Very young banana plants can be killed simply by digging them up. This process is more difficult with older plants, which have a larger root system. To remove the banana plant, dig up a circle of soil about 1 foot around the base.Insert the blade of a sharp shovel into the disturbed dirt at a 45-degree angle to sever any underground roots, working all the way around the plant. After the roots have been severed, you can easily pull the young banana plant up.Leave the roots exposed to kill the plant completely.o remove the banana plant, dig up a circle of soil about 1 foot around the base.
