subtropical
A temperate and subtropical wilt of cucumber which caused up to 40% losses in Florida in 1949. The pathogen causes pre-emergence and post-emergence damping-off and wilt of older plants. In Florida mature plants with runners may first show wilt in a single crown branch, followed by collapse of the whole plant. Vascular necrosis may extend into the vine for 6-8 nodes (35: 265, 266). A cortical decay, absent from older plants, occurs in seedlings. In England, wilt symptoms have been described as beginning in the lower leaves and the vascular system of the lower nodes becomes prominent, standing out as white lines (45, 3013)
