최근(最近) 재배(栽培) 면적(面積)과 수요(需要)가 급증(急增)되고 있는 구기자(拘杞子) 재배시(栽培時) 치명적(致命的) 피해(被害)를 주는 구기자(拘杞子) 탄저병(炭疽病)에 대한 약제(藥劑) 시험(試驗) 결과(結果) 1. 탄저병(炭疽病) 발병(發病) 시간(時間)는 7월 중순(中旬)과 8월 중순이 가장 심(甚) 하였으며 평균온도(平均溫度) 25℃ 전후(前後)의 조건하(條件下)에서 발병율(發病率)이 가장 높았다. 2. 운곡면(雲谷面)과 대치면(大?面) 모두 프로피 수화제의 방제가(防除價)가 81.5%와 93.4%를 나타내어 약효(藥效)가 가장 우수(優秀)하였다. 3. 디치돈 수화제와 프로피 수화제 모두 기준량(基準量)과 배양(倍量) 공히 약해(藥害)가 발생(發生)하지 않았다.
This study was carried out to select chemicals those are effective for the control of Colletotrichum gloeosporioides of Lycium chinense Miller. Dithidone and Propy wettable powders (WP) were treated to Chungyang native variety for the test of control effect The effect was examined after dilution the solution with 500 times, and chemicals injury was treated with 250 times of diluted solution. The results were as follows ; 1. Occurrence of the disease was most serious in min- Ju1y and in mid- August, and the attacking of the disease was highest at about 25℃ of growing temperature. 2. The control of Propy WP was most effective and its control value was average 81.5% in the treated area. 3. Chemicals injury of Dithidone and Propy was not occurred at the double-diluted solution trestment.
