Abstract: | The objective of this study was to estimate the effects of tillage systems and cover crops on the incidence of root rot in melon and to identify the fungal pathogens associated with the disease. Two consecutive trials were carried out in a randomized complete block design with four replications in each trial. The treatments were arranged in split-plots. Two tillage systems (no-tillage (NT) and conventional tillage (CT)) were assigned in the main plots and in the subplot the six types of ground cover crops were tested (sunn hemp, pearl millet, sunn hemp + pearl millet, corn + brachiaria, spontaneous vegetation, spontaneous vegetation + polyethylene film) or bare soil. At the end of the trials all melon plants were collected and assessed for disease incidence, isolations from symptomatic plants were made for fungal identification. Root rot incidence was lower in the NT treatments with sunn hemp, pearl millet, and spontaneous vegetation. The main fungi isolated from symptomatic roots were Fusarium solani, Macrophomina phaseolina, Monosporascus cannonballus and Rhizoctonia solani, but F. solani was the most frequently isolated fungus in both tillage systems. The results suggest that the NT system has the potential to control incidence of root rot of muskmelon, but is necessary to realize crop rotation between the planting cycles. |
