Verticut / scarify
“Thatch” build up is one of the major contributory factors in the development of Fusarium Patch disease. “Thatch” provides un-decomposed organic material for the pathogen to exist during unfavourable conditions (e.g. dry conditions in summer). When more favourable environmental conditions return the Fusarium enters the pathogenic phase of its life cycle and attacks the living plants. The moisture retentive nature of the “Thatch” provides ideal conditions for the rapid infection of swards. Regular Verti-Cutting and scarification are important methods of preventing “Thatch” build up and are therefore important cultural methods for reducing the incidence/severity of Fusarium Patch.
