Annual weed competition in young orchards and vineyards can often reduce first-year growth as much as 50 percent. In fields with extremely heavy weed populations and limited irrigation, trees and vines have been killed by weeds in the first year. Perennial weeds are even more harmful than annual weeds to newly planted trees and vines. Even though a persistent tillage program can give a practical control of perennial grasses, many growers still have serious problems with perennial weeds.
