SUMMARY The control of volunteer soybean (Glycine max) plants between crop seasons is mandatory due to the increasing incidence of diseases, mainly Asian soybean rust (Phakopsora pachyrhizi). Moreover, competition from volunteer soybean plants can cause yield losses in other crops. The objectives of this study were to evaluate the control of volunteer soybean plants by sulfentrazone doses and selectivity in sunflower crop (Helianthus annuus). Two experiments were carried out under field conditions in the municipality of Rio Verde, Goiás State, Brazil. The experimental design was randomized complete blocks with four replications. Treatments applied in Experiment 1 were sulfentrazone 0, 25, 50, 100 and 150g·ha-1 and hoed check. The same treatments were applied in Experiment 2 plus sulfentrazone 200 and 250g·ha-1. Polynomial regression models were fitted to the data of percentage of sunflower phytotoxicity, percentage of soybean control, sunflower plant height, head diameter, sunflower grain yield and dry biomass of volunteer soybean plants. Doses ranging from 114.1 to 158.8g·ha-1 provided the highest sunflower yield, preventing the competition of volunteer soybean plants with the crop. Sulfentrazone did not completely eliminate the volunteer soybean plants, but there was a temporary stoppage of soybean growth that enabled the initial startup of the sunflower plants. |
