LONDERO, Eduardo Kneipp et al. Influences of different control periods and coexistence with weed in eucaliptus. CERNE [online]. 2012, vol.18, n.3, pp.441-447. ISSN 0104-7760. http://dx.doi.org/10.1590/S0104-77602012000300011.
This work studied the periods of control and coexistence of weeds with eucalyptus culture. The experiment was led in Candiota, RS, in the period from January to December, 2006. The treatments consisted of different control times and coexistence of the culture, these periods were divided in two groups; one was to determine the Period Previous to the Interference (PPI) and the other to define the Total Period of Prevention of the Interference (TPFI). In the two groups the tested periods were: 00, 28, 56, 84, 112, 140, 168, 210, 252, 294 and 336 days. The young trees of eucalyptus were susceptible to weed, presenting a period previous to the interference of 56 days. In order to guarantee its largest production, the total period of prevention of the interference was 140 days and the period previous to the interference was of 56 days.
