RESUMO

ABSTRACT There are several techniques for the control and removal of invasive species that can be applied, and there is a demand among restoration practitioners for plant control methods. This study compared two methods for the control of jackfruit tree: mechanical method of trunk girdling and chemical method of herbicide injection into the trunk. It was evaluated both methods in terms of effectiveness in 10 plots (80 × 80 m). For the chemical method, triclopyr in concentrations of 2%, 6% and 8% was used. The progress of treatments was evaluated accordingly for the phytosanitary conditions. Method of trunk girdling proved to be ineffective and it had a low mortality rate (12%). The proportion of dead trees by chemical treatment was 100%. The results showed that chemical control of jackfruit trees was much faster and more effective.
