Potential use of the new herbicide indaziflam in banana orchards
Weed control is one of the capital requirements to provide suitable growth and establishment of banana orchards. However, very few options of herbicides are available for this crop. From this context, the objective of this work is to evaluate weed control and selectivity of the new herbicide indaziflam apllied pre-emergence in a directed spray to the inter rows area of banana orchards, targeting the weeds hairy flebane (Conyza bonariensis), Jamaican crabgrass (Digitaria horizontalis) and spiny sandbur (Cenchrus echinatus). A field experiment was carried out in a randomized blocks desingn, with four replicates. Treatments were composed by indaziflam applied pre-emergence of weeds at doses of 50, 75, 100 and 125 g ha-1; glyphosate applied post-emergence at 1920 g a.e. ha-1, and two controls: weedy and absolute (weed-free, with no herbicide application). Indaziflam at 75, 100 and 125 g ha-1 provided excellent control of all main weeds in the experimental area for a period of 120 days. All rates of indaziflam applied pre-emergence of weeds were considered as selectives for banana trees, since no visual injury or crop yield effect was observed. Indaziflam presents potential as a new herbicide alternative in banana orchards.
