The objective of the ECOCANNE project is to develop an integrated agroecological strategy for weed control using cover crops and stem borer control using push-pull mechanisms, possibly combined with biological control. This is a dataset from the P25_LEG trial studying sugarcane in association with cover crops. An irrigated trial on sugarcane in regrowth 4, was set up in 2015 and harvested in 2016, at the La Mare experimental site.
