| ABSTRACT: The repetitive use of glyphosate in the control of weeds in eucalyptus plantations has selected tolerant species such as Commelina benghalensis. Therefore, the use of herbicides of other mechanisms of action, such as saflufenacil, in rotation or combination with glyphosate, is necessary to reduce damages caused by C. benghalensis, whose sensitivity to herbicides can be influenced by the shading caused by the eucalyptus crop. This study aimed to assess the efficiency of saflufenacil in the management of C. benghalensis at different shading levels. Three experiments were carried out regarding a certain shading level (cultivation environment with 0, 40, and 55% shade). The experimental design was a randomized block design with five herbicide doses... |

| ABSTRACT: Herbicide drift, due to application failures, can cause intoxication in eucalyptus plants, compromising their growth. However, the addition of protective products such as Fertiactyl Pós® to the syrup has been shown to be efficient in reducing intoxication of eucalyptus plants exposed to herbicide drift. Given this, the objective of the present study was to evaluate the protective effect of Fertiactyl Pós® on the reduction of damage caused by the herbicides glyphosate, 2,4-D and the glyphosate + 2.4-D mixture in eucalyptus plants. The experiment was conducted in a 3 x 2 + 1 factorial scheme, corresponding to three herbicides: glyphosate (1,440 g ha-1), 2,4-D (680 g ha-1), glyphosate + 2.4- D (1,440 g ha-1 + 680 g ha-1); two doses of Fertiactyl... |
