Four cotton (Gossypium hirsutum) genotypes and three biweekly planting dates, beginning during late March, were examined for 3 yr in a split-plot field design to determine effects on Fusarium wilt development. Cotton genotypes included Acala SJ-2, susceptible to Fusarium oxysporum f. sp. vasinfecium and Meloidogyne incognita; Acala SJC-1, tolerant of F. o. vasinfectum and susceptible to M. incognita; N6072, susceptible to F. o. vasinfectum and resistant to M. incognita; and N8577, tolerant of F, o. vasinfectum and resistant to M, incognita. Fusarium wilt disease was low, moderate, and severe, for 3 yr, respectively. A planting-date effect of more Fusarium wilt in earlier plantings was found and was most evident in Acala SJ-2 [...]
