Herbicida indaziflam NO CONTROLE DE PLANTAS NA CANA-DE-AÇÚCAR

Abstract

The present work aimed to compare the efficiency of the new herbicide indaziflam with other registered herbicides of classical use in the control of important weeds on sugarcane culture. The study was conducted in the experimental area of ​​SGS of Brazil, Rio Verde unit - Goiás, Brazil, the experimental design adopted was in blocks randomized with plots subdivided into space, with 6 treatments (5 herbicides + 1 control) and 6 weed species with 4 replications. The demarcation of the plots with weed sowing, with each species sown in 0.25 m2 central region of each 6m 2 plot. In the subplots, the seeds were sown following weed species: Digitaria insularis, Eleusine indica, Urochloa decumbens, Euphrobia heterophyla, Merremia aegyptia and Ipomoea grandifolia. The amount of weed seeds of each species was determined to obtain 50 plants, based on the germination test of the acquired seeds. Subsequently, the herbicide application in pre-emergence of crop and weeds. The treatments herbicides were: sulfentrazone, diuron, indaziflam, s-metolachlor and tebutiurom Weed control efficiency evaluations were performed at 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 days after the application of the treatments. It was initially observed in Compared to other treatments indaziflam efficiently controlled only grass species, but maintained good residual control during the period evaluated. Being thus passes an option for action mechanism rotation.
