摘要

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%。其中Anthio加Mon之處理，不但加深果皮紅色，且採收後炭疽病之罹病率較少。同時於4月下旬使用Antibiotic之Poimy加殺蟲劑處理之紙袋與一般使用之耐水紙袋，套果防治潰瘍病、炭疽病及果蠅之比較結果，以耐水紙袋套果者，潰瘍病之發生較爲嚴重，但以藥劑處理紙袋套果者，即未發見病蟲害之爲害。總之，4~6月之果實發育期，因果蠅尚未爲害則不必套袋，應以0.175% Antracol WP.及0.0165% Mon EC.混合殺菌劑，每隔7~10天防治3~6次即可抑制潰瘍病、炭疽病及害蟲之爲害。6~7月果實成熟期，爲防果蠅產卵爲害，以0.05男Anthio EC.及0.047% Sumithion WP.混合殺菌劑，每隔7~10天防治3~4次，即可減少果蠅及炭疽病之爲害。

並列摘要

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.
The results of the experiments were shown that the treatments of 0.05% Anthio EC.+0.0165% Mon EC. spraying at 7-day intervals; 0.047% Sumithion WP. + 0.125% Orthocide WP. spraying at 10-day intervals, or 0.05% Lebaycid EC.+ 0.175% Antracol WP. 0.10% Malathion EC. + 0.20% Dithane M22 WP. and 0.05% Perfekthion EC.+0.20% Poly-ram combi spraying at 15-day intervals get more than 80% of the pests controlling effect. Among them, the combination of 0.05% Anthio EC.+0.0165% Mon EC. had the effect on deepenning red color on mango fruit. Wraping fruit with paper could against the damage of fruit fly, however, it caused severely damage of Anthracnose and Canker diseases.
