摘要

Carrot (Daucus carota L.) is a vegetable crop that is grown throughout the year across various regions of Brazil in rotation or in succession to other cultures. Herbicide residual effect has emerged as a concern, because of the possibility of carryover. Thus, the objective of this study was to evaluatethe effect of tembotrione and atrazine residues - in mixture and isolated - on carrot planted in succession to corn. The experiment was designed in randomized blocks with five replications. Treatments consisted of tembotrione (50.4 g ha~(-1)), tembotrione (100.8 g ha~(-1)), tembotrione + atrazine (50.4 g ha~(-1) + 2 L ha~(-1)), tembotrione + atrazine (100.8 g ha~(-1)+ 2 L ha~(-1)), and atrazine (2.00 L ha~(-1)) applied eight months before carrot seeding, plus a control treatment with no herbicide application. Investigated variables were shoot dry mass, productivity, and classification of carrot roots. The presence of atrazine and tembotrione decreased dry mass in the area, and only tembotrione reduced total root productivity. Thus, there is a carryover effect to tembotrione application that reduces the dry matter accumulation of shoot and total productivity, and an atrazine + tembotrione (100.8 g ha~(-1)) mixture reduces the total productivity after application of these herbicides to soil.
