Monitoring phytopatogens in soybean and maize crops in the ilpf system of Embrapa Agrosilvopastoral.
Abstract: Since the 2011/2012 crop season, Embrapa Agrosilvopastoral in Sinop/MT has conducted na experiment of crop-livestock-forest integration, consisting of 10 treatments. The objective of this work was to monitor the incidence and severity of diseases in soybean and corn crops. The treatments studied were: LAV (soybean crop followed by corn + brachiaria), ILPF1 (crop-livestock-forest integration, crop rotation with livestock every 2 years); ILPF2 (crop-livestock-forest integration, with crop and animal entry after the corn harvest, every year); ILP (crop-livestock integration, crop and rotation with livestock every 2 years) and ILF (crop-forest integration). A randomized complete block design was used, with 4 replications. Analysis of variance and the means were compared using the Tukey test at 5% probability. In the soybean crop, in the 2011/2012 and 2012/2013 harvests, there were no diseases. In subsequent harvests, the incidence of target spot was always observed in the R5.1 phase. In the corn crop, in the years 2014, 2016 and 2019 the incidence of diseases was not observed. Bipolar spot was observed in 2017 and cercosporiosis was observed in the years 2015, 2017, 2018 and 2020. In both cultures, the incidence of diseases did not differ between treatments.
