The experiment aimed to evaluate the clomazone (alone or in mixture with atrazine) drift off simulation, on quantitative and qualitative aspects of the sweet orange production when occurred at developmental plant stages of fruit growing (fruits of 2 until 4 cm diameter). Crescents doses, until commercial rate, of clomazone, in two formulations, and in mixture with ametryne were tested. The experimental design was completely randomized blocks, with 15 treatments and 3 replications. It was evaluate: fruit morphological feature, fruits abortion and leaf chlorophyll content. Clomazone alone at of commercial rate and in mixture with ametryne at 50 and 100% promoted clorotic and/or necrotic spots in the fruit skin and promoted the death of new sprouting stems. There were no qualitative effects on juice.
