Abstract
莫拉克颱風侵襲台灣，造成高屏地區的蓮霧產業嚴重損失。蓮霧的病害問題除了栽培過程中之炭疽病、果腐病、疫病、霉腐病、藻斑病、煤病及青枯病外，還有採收後貯運或儲藏時所發生的果實病變腐壞。蓮霧果園，應用田間衛生管理、適當的栽培管理，適時施用藥劑，噴藥後施行套袋保護，對蓮霧果實病可獲得良好的防治效果，對蓮霧之疫病、炭疽病以及黑腐病之防治率都可達 90%以上。颱風除造成蓮霧小果的傷害外，並提供適合的發病環境，颱風後連續降雨使藥劑防治工作效果不佳甚至無法進行，因而造成大規模的危害。此外，蓮霧預防寒害，可在寒流來襲之前葉面施用鈣、鉀肥，以增加細胞的溶質濃度，並活化細胞組織，提高耐寒力。
Typhoon Morac caused huge damage of Wax-apple in Kaohsiung and Pingtung areas of Taiwan. The reference recorded that seven major diseases have been found, i. e. anthracnose (Colletotrichum gloeosporiodies), black rot (Botryodiplodia theobromae), Phytophthora fruit rot (Phytophthora palmivora), fruit rot (Pestalotiopsis euginae), algal spot (Cephaleuros virescens), sooty mold (Capnodium sp.), and soft rot (Rhizopus stolonifer). An integrated control measure is suggested that one application of fungicidal spray during young fruit stage followed by bagging with silica gel showed 90% effective against diseases.
The typhoon rain falls not only cause young wax-apple fruit damage but also suitable for several major diseases developed, even disturbed fungicidal spray working. Foliar application of calcium before the cold weather comes, potash, to increase the solute concentration of cells, and activation of cells and tissues, improve chill tolerance.
