Soil Borne Pathogens- Molecular methods • Nucleotide sequencing – most accurate method • ITS -internal transcribed spacer- non-functional RNA sequence. Widely used because it is easy to amplify even from small quantities and has a high degree of variation even between closely related species.
Most Common Strawberry Root and Crown Pathogens • Anthracnose – Colletotricum acutatum • Black Root Rot –Cylindrocarpon spp. • Fusarium Wilt – Fusarium oxysporum • Charcoal Rot –Macrophomina phaseolina • Phytophthora –several species • Verticillium Wilt – Verticillium dahliae • Nematodes – several species
