Abstract
Fruit rot in loquat (Eriobotrya japonica) was suppressed effectively by covering the roof of the plastic greenhouse with polyethylene film early in the season. Early roof covering intercepted rain during the flowering stage of loquat. The fungi that caused fruit rot were primarily Pestalotiopsis sp. and Colletotrichum sp., although other fungi were also observed on some rotten fruits. This control practice was statistically estimated to reduce the risk of fruit rot to as low as 20% of that using conventional practices.
