Growth Performance and Field Evaluation of Herbicide-Resistant Transgenic Creeping Bentgrass Lee, Ki-Won; Lee, Byung-Hyun; Seo, Bo-Ram; Kim, Jin-Seog; Lee, Sang-Hoon;
This study examined the growth performance and field evaluation of the dual herbicide-resistant transgenic creeping bentgrass plants. The effect of glyphosate treatment on the herbicide resistance of the transgenic creeping bentgrass plants was determined, and the non-transgenic control plant withered at the concentration or higher whereas the transgenic creeping bentgrass plants survived the treatment at the concentration of , and the increase of the plant length was repressed as the glyphosate treatment concentration was increased. At field evaluation, glufosinate-ammonium and glyphosate were simultaneously treated to investigate the weed control effect. The results showed that more than 90% of the weeds withered four week after herbicide treatment, while the transgenic creeping bentgrass plants continued to grow normally. Therefore, the dual herbicide-resistant creeping bentgrass plants may be able to greatly contribute to the efficiency of weed control and to the economic feasibility of mowing in places such as golf courses.
