Biological parameters to control of walnut anthracnose agent Gnomonia leptostyla (Fr.) Ces et de Not. in Central Anatolian conditions
Abstract
The main disease of walnut is anthracnose caused by Gnomonia leptostyla (Fr.) Ces et de Not. The disease is very destructive when the conditions are favorable for disease growth. This study was conducted in Oğuzlar district of Çorum province, one of the largest walnut growing regions of Turkey from 2005 to 2011. Biological parameters (phenological stage of walnut, the dates of perithecia maturing and infection, climate etc.) to control the disease were obtained during the study. Walnut trees were damaged due to the late spring frost in 2006 and hail in 2007, and their effects continued in 2008. During these years, yield was low in trees and the trees turned to vegetative growth. According to years, perithecia matured from March 21 to April 6; primer infections occurred from April 17 to May 8; seconder infections happened from May 15 to June 12. These stages were beginning to burst of buds, and cat ear stage; the stage when the leaves passed half the size; the stage when the fruits were big hazelnut, respectively.
