Fatty Alcohol 處理 時期와 濃度가 黃色種 담배의 下部腋芽의 除去에 미치는 影響 = Effect of Concentration and Spraying Time of Fatty Alcohol on the Ground Sucker Control of Flue-cured Tobacco

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the effects of concentration and spraying time of Fatty Alcohol(Anti-suc) on the ground sucker control of flue-cured tobacco (var. NC 82) in 1996. The results are as follows.
1.Though the higher concentration of fatty alcohol sprayed showed more effective in controlling ground suckers of flue-cured tobacco, 30 times dilution treatment showed satisfactory control of ground suckers as compared to the hand suckering.
2.Ten times diluted fatty alcohol treatment damaged significantly the harvestable leaf lamina, basal part of midrib(leaf axil) of the lower leaves and cortex of stem near soil surface. 30 times dilution treatment damaged little on the leaf and stem.
3.Spraying time of fatty alcohol solution in this experiment showed little differences of the effects on the control of ground suckers. It is likely that spraying solution 50 days after transplanting is more advantageous in working convenience and in labor saving than 40 days application.
4.Ground sucker control by fatty alcohol spraying saved labor hours and increase income significantly as compared to the hand suckering.
