Lesion Nematode: Pratylenchus spp. infestations cause brown lesions on surface and cortex of roots. Symptoms include wilting and chlorosis in heavy infestations. Lesion nematodes have a wide host range. Hemp-specific reports of nematode infestations are limited, likely resulting from limited nematology programs in the US. Many nematode species have broad host ranges, so one can assume that nematodes can become problematic at sites where nematode populations are high.
Stubby Root Nematode: Trichodorus spp. Infestations cause root damage that results in stubby roots. Plants become stunted and chlorotic. Stubby root nematodes have a wide host range, including vegetable crops. Hemp-specific reports of nematode infestations are limited, likely resulting from limited nematology programs in the US. Many nematode species have broad host ranges, so one can assume that nematodes can become problematic at sites where nematode populations are high.
Root Knot Nematode: Meloidogyne spp. Infestations cause galls on roots. Above-ground symptoms include stunting, chlorosis, and wilting. Root knot nematodes have a wide host range, including cannabis. Hemp-specific reports of nematode infestations are limited, likely resulting from limited nematology programs in the US. Many nematode species have broad host ranges, so one can assume that nematodes can become problematic at sites where nematode populations are high.
