摘要:

Two alternatives to chemical control ofBotrytisin strawberries were assessed, post-harvest defoliation and finger harrowing, the latter being used primarily in weed control but also claimed to affect the occurrence ofBotrytis.Post-harvest defoliation, though having some positive effect on marketable yield, did not reduce the incidence ofBotrytissignificantly. This was the case regardless of whether or not cut leaf material was removed from the plots. Finger harrowing, though in some instances having a negative effect on yield, did not controlBotrytissignificantly either. However, it was clearly demonstrated that, in organic strawberry growing, the incidence ofBotrytisincreases with plant age. Therefore, a short-term cropping system may be more important in controllingBotrytisthan either post-harvest defoliation or finger harrowing. In conclusion, the combined use of several cultural methods may be needed when controllingBotrytisin organically grown strawberries.
