In Brazil, there are several stains and rusts, many of which occur silently, but which reduce productivity. Among these multiple foliar diseases most commonly found, seven occur in the cooperative network trials (Figure 1). The importance of each of them, as well as the best period for monitoring, varies, depending on the crop and the region of cultivation and hybrid (Figure 2). This requires producers and technical assistance to improve the positioning of fungicides for control.
