Abstract
To quantify the weed detrimental effect during the first two growing seasons, two field experiments were conducted at Portezuelo (72°24' Long W - 36°31' Lat S) and Pemuco (72°11' Long W - 36°58' Lat S). Also, the required weed control intensity and the accumulative effect of the two first years of weed control were determined. The pine plants' biomass index (D2H) decreased 65% when weeds were not controlled during the second year. A broad weed control programme was not necessary during the second year, being strip application of herbicides enough. When the area controlled was only equivalent to a "spotgun" application, pine plants grew as poorly as the ones in the weedy area during the second year.
