  Studies showed that both airborne seed infection of B.cinerea have been implied as major sources of primary inoculum in different part of lettuce plant. Results from quantitative real-time PCR and visual observations showed that seed infection was the main source of inoculum in the field trial conducted in this study. However, glasshouse studies established that the pathogen can be transmitted from infected seeds into roots, shoots and leaves without showing symptoms. Plants in the field trial remained free of infection for approximately four months before symptoms were observed in the crop. Covering the crop during part of the growing season was found to prevent the growth of the pathogen, despite the use of infected seed, which indicate that changes in the physiological condition of the plant and/or environmental conditions most especially over wate..
