In papaya culture, there is little information on selective herbicides when pre-emergence applied. A field experiment was conducted to evaluate the selectivity and efficacy of herbicides pre-emergence applied to control weeds in papaya cultivation. The experiment was conducted in a randomized blocks design with four replications. The treatments were: ametryn (1500 g ha-1 i.a.), diuron (1500 g ha-1 i.a), ametryn + diuron (1500 + 1500 g ha-1 i.a.), flumioxazin (50 g ha-1 i.a.) and isoxaflutole (150 g ha-1 i.a.), applied […]
