Sensibility of plant species to herbicides aminocyclopyrachlor and indaziflam
Aminocyclopyrachlor and indaziflam are under development in Brazil and there is no information about their behavior in Brazilian soils. This study aimed to evaluate the sensitivity of plant species to these new molecules, trying to select plants that can be used as bioindicators for testing the behavior of these herbicides in the soil. Two experiments were conducted, one for each herbicide. The treatments were arranged in a 8 x 6 factorial design, the factors being represented by eight species used as bioindicators cotton, maize, soybean, sorghum, sunflower, millet, cucumber and beet, and six doses of herbicides (aminocyclopyrachlor - 0, 10 , 20, 30 , 40 and 50 g ha-1 and indaziflam 0 , 20, 40 , 60, 80 and 100 g ha-1). Among the species studied, soybean and beet were quite sensitive to the two new herbicide molecules, being great alternatives for bioassays in order to detect low concentrations of aminocyclopyrachlor and indaziflam in the soil.
