Abstract
本年度在玉井檬果園於4~8月果實發育期間，以7種殺菌劑及殺蟲劑混合防治檬果潰瘍病、炭疽病及果蠅之效果觀察，每種藥劑分別以每隔7天防治10次，每隔10天防冶8次，每隔15天防冶6次。結果檬果炭疽病、潰瘍病及果蠅之綜合防治率已達到80%以上，如每10天防治之0.125% Orthocid WP. + 0.047% Sumithion WP.達86.94%，每15天防冶之0.175% Antracol WP. + 0.05% Lebaycide E.C.達86.45%，及0.2% Dithane M22 WP.+0.1% malathin EC.達85.62%，每7天防治之0.0165% Mon EC.+ 0.05% Anthic EC.達83.31%，每15天防治之0.2% Poly-ram Combi WP.+0.05% Perfekthion EC.達80.38%。
The tip-borer (Chlumetia transversa Walker), fruit fly (Chaetodacus ferrugineus dorsalis Hendel) and Anthracnose (Glomerella cingulata S. et. S.) Canker (Bacillus sp. ?) diseases are considered the most important pests of mango on this island. The combined attack of these pests on mango usually occasion enormous losses of the crop, especially on those newly introduced varieties such as Irwin. The present experiment is conducted to evaluate some conbinations of fungicides and insecticides for their pests controlling effect at Yu-Ching Tai-Nan district from April to August, 1970.
