Zeytinde Verticillium solgunluğu

Zeytin ağaçlarında Verticillium dahliae' nin neden olduğu solgunluk, Akdeniz ülkelerinde zeytinin en önemli hastalıklarından biridir. Hastalık dallarda kuruma veya ağacın tümden ölmesi biçiminde ortaya çıkar. Yaşlı ağaçlar da Verticillium solgunluğundan etkilenebilirler ancak hastalığın yaygınlığı ve şiddeti, özellikle etmenle bulaşık arazilerde tesis edilmiş genç zeytinliklerde genellikle en yüksektir. Diğer bazı ağaç türlerinde olduğu gibi VerticiUium solgunluğundan etkilenen zeytin ağaçlarının da iyileşmeleri sık rastlanan bir olaydır. Henüz hiçbir fungisid zeytinlerdeki Verticillium solgunluğunu önleyemediği veya kontrol edemediği için, hastalığın mücadelesi koruyucu önlemler ve kültürel yöntemleri içeren bir entegre stratejiye dayanmalıdır.

Verticillium wilt of olive

Verticillium wilt of olive, caused by Verticillium dahliae, is one of the most serious diseases of olive trees in several Mediterranean countries. The disease is characterised by dieback of twigs or death of entire trees. Although old trees may be affected by Verticillium wilt, disease incidence and severity are usually the highest in irrigated young orchards, especially those established in V. dahliae-infested soil. As in some other tree species, recovery of the affected olive trees from Verticillium wilt is a very common phenomenon. Since any fungicide is still unable to prevent or control Verticillium wilt in olive, control of the disease should be based on an integrated strategy, involving the application of preventative measures and cultural methods.
