⚡ TL;DR(Too Long; Didn't Read)

It was concluded that C. chrysosperma infects poplars at the nursery stage and it can infect healthy trees via vectors, wind and rain, and the distribution of the disease spreads out in regional scale via the delivery of the infected poplar saplings; due to be a wound parasite, the disease infects poplars at the scars caused by insects and other factors; and it is an important factor in high infection ratio of the disease that control methods not being well known.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:This study is carried out in 2003-2005 in order to determine the biology and control of Cytospora canker Cytospora chrysosperma “Pers” Fr. and Poplar Clearwing Moth [Paranthrene tabaniformis (Rott.)] and their control methods in poplar sites in Çankırı.It was determined that C. chrysosperma’s spor release dates and the flight period of P. tabaniformis were similar and the hibernation studies on the pathogen showed that it overwinters actively in Çankırı, and P. tabaniformis adults could be trapped in pheromone traps after the sum of the effective temperatures reaches 120 degree-days and the mean temperature reaches 17°C.

Abstract

This study is carried out in 2003-2005 in order to determine the biology and control of Cytospora canker Cytospora chrysosperma “Pers” Fr. and Poplar Clearwing Moth [Paranthrene tabaniformis (Rott.)] and their control methods in poplar sites in Çankırı.It was determined that C. chrysosperma’s spor release dates and the flight period of P. tabaniformis were similar and the hibernation studies on the pathogen showed that it overwinters actively in Çankırı, and P. tabaniformis adults could be trapped in pheromone traps after the sum of the effective temperatures reaches 120 degree-days and the mean temperature reaches 17°C. It was concluded that C. chrysosperma infects poplars at the nursery stage and it can infect healthy trees via vectors, wind and rain, and the distribution of the disease spreads out in regional scale via the delivery of the infected poplar saplings; due to be a wound parasite, the disease infects poplars at the scars caused by insects and other factors; and it is an important factor in high infection ratio of the disease that control methods not being well known.

Özet

Çankırı kavak alanlarında Cytospora Kavak Kanseri’nin biyolojisi ile Saydam Kanatlı Kavak Kelebeği (P. tabaniformis)’nin popülasyon seyri ve bunların mücadele imkanlarını araştırmak üzere ele alınan bu çalışma 2003–2005 yılları arasında yürütülmüştür. C. chrysosperma’nın piknitlerden spor salınım tarihleri ile P. tabaniformis’in uçuş periyotlarının tamamen örtüştükleri; patojen ile yapılan kışlama çalışmalarında, Çankırı bölgesinde patojenin kışı aktif olarak geçirdiği bulunmuştur. Etkili sıcaklık toplamının 120 gün-dereceye ve hava sıcaklığının 17°C’ye ulaşmasından sonra feromon tuzaklarda P. tabaniformis erginlerinin yakalanabileceği anlaşılmıştır. C. chrysosperma hastalığının, kavak fidan üretim alanlarında özellikle üretim aşamasında bulaştığı, yayılmasında hastalığın vektör, rüzgar ve yağmurla sağlıklı ağaçlara bulaştığı; hastalık ve zararlılarla bulaşık fidanların üreticilere ulaşmasıyla yayılış alanlarının bölge düzeyinde genişlediği; fungal etmen yara paraziti olduğundan böcek ve/veya başka faktörler nedeniyle meydana gelen yaralardan giriş yaparak hastalık oluşumuna neden oldukları, bulaşıklılığın yüksek olmasında, bu hastalıkla mücadele yöntemlerinin yeterince bilinmemesinin de etkili olduğu kanısına varılmıştır.
