Abstract: 

Weeds impair the productive efficiency of agricultural crops, a species that has shown an increase in occurrence is the melon-de-são-caetano (Momordica charantia L.), and this causes losses due to competition for water, light, nutrients and space. Therefore, a treatment with an effective herbicide to control this species is of utmost importance for the reduction of the damage caused. Therefore, the present work aimed to evaluate different herbicide molecules associated with irrigation intervals in the control of são caetano melon (Mormodica charantia L.). The experiment was conducted at the Agricultural Engineering and Sciences Campus of the Federal University of Alagoas (CECA / UFAL). The design used was completely randomized in a 5x5 factorial scheme, with three replications. The study species Mormodica charantia was subjected to four combinations of herbicides [alion + jump, alion + sencor, alion + ametrina, alion + boral, being represented by H1 H2 H3 H4, respectively and a control without herbicide (H5)] associated with five irrigation intervals [0, 7, 14, 21 and 28 days after application (DAA)]. The treatments H1, H2 and H4 were combated 100% of Mormodica charantia in all the analyzed irrigation intervals, showing to be efficient in the control of this species.
