Abstract
Chestnut blight has become a permenant threat to chestnut cultivation of Turkey.
The disease was first recorded in the Marmara Region of Turkey in 1967. Since then its occurrence has been reported from various chestnut producing areas of Turkey and finally from the Aydın Province which is the leading chestnut producer of Turkey.
In Turkey yield losses due to chestnut blight has not been assessed so far, but the gradual loss of total chestnut production since 1992 was mainly attributed to chestnut blight.
In Turkey most of the studies on chestnut blight and its agent have been conducted since the reduction in production became noticeable and significance of its damage on chestnut population was recognised.
Basic and applied researches mainly on its spread, characterization of Turkish isolates and control of the disease have been conducted.
Unfortunately so far no method has been implemented into practice in order to achieve a succesfull control of the disease in Turkey.
So that most of the chestnut producers have been trying to cobmat the disease their own way or by taking the recommendations of other producers.
The attemps and efforts to sustain chestnut and to slow down the spread of the pathogen, before reaching to uncontrolable levels will help to reduce the destruction and the yield loss in Turkey.
These practices are also crucial in reducing the risk of disappearance of the present genetic constitution of the current Turkish chestnut population.
So that legislative and phytosanitary measures should be immediately applied in order to reduce the impact of C. parasitica while waiting the completion of long term projects such as introduction of suitable hypovirulent strains, selection and breeding blight resistant cultivars.
