Fertilization and Irrigation Effect on Botryosphaeriaceae Canker Development in Intensively Managed Sweetgum (Liquidambar styraciflua)
The influence of irrigation and fertilization on the response of sweetgum (Liquidambar styraciflua L.) to branch inoculation by species in the Bo - tryosphaeriaceae family, Botryosphaeria dothidea (Moug.:Fr.) Ces. & De Not and Lasiodiplodia theobromae (Pat.) Griffon & Maubl., was tested over summer and winter seasons for 2 years. Sweetgum planted in South Carolina received irrigation, fertil - ization, fertilization + irrigation, or no amendments April to September each year. Both Botryosphaeriaceae inoculants caused larger cankers compared with the water agar control with the exception of one winter season, in which L. theobromae canker development was insignificant. The irrigation and fertilization amendments, on an individual level, did not directly affect canker development of these Botryosphaeriaceae pathogens on sweetgum; however, an interaction did occur between the amend - ments and season. By the summer of 2004, plots with the amendments had larger trees than plots with no amendments, leading to more crown closure. The resulting shading of inoculated branches in these plots likely contributed to larger cankers.
