Weeds in Forestry and Possibilities of Their Control

However, all weeds do not have equal significance. When considering weed control attibutes, perennial weeds present are far greater challange due to difficulties employing mechanical means, because perennials are often stimulated to grow and disperse even more intensively. Perennial weed species, such as Sorghum halepense, Convolvulus arvensis, and Cynodon dactylon, have well-developed underground organs and are great problems not only in agriculture, but also in nursery production of forest planting materials.
