Paraconiothyrium tiliae

Tilia leaf spot fungus

Description

Paraconiothyrium tiliae, also known as Asteromella tiliae or Didymosphaeria petrakiana, is a harmful pest that affects Tilia (linden or lime) trees. It causes leaf spot disease, leading to distinct lesions on the foliage. The lesions expand, merge, and result in irregular-shaped patches. Net-like margins. Infected leaves turn brown or yellow and may fall down prematurely. The pathogen spreads through spores carried by wind, rain, or insects. The severity of the infestation depends on various factors. Cultural practices like proper tree spacing, pruning, and debris removal help reduce the risk. Maintaining optimal soil moisture is crucial. Chemical treatments can be considered in severe cases. Early detection and professional consultation are important for effective management.
