  • Laboratory and greenhouse studies were conducted to evaluate effects of spray volumes and surfactants, L-77 and Triton CS-7 on leaf retention of glyphosate in Zea mays, Hordeum vulgare, Artemisia princeps, Trifolium repens and Equisetum arvense. Leaf retention was increased when glyphosate with L-77 or Triton CS-7 was applied in a spray volumes of 10-20 l/10a in Zea mays and 40 l/10a in Artemisia princeps but decreased when spray volumes were higher than above volumes and 40-80 l/10a in Trifolium repens. Hordeum vulgare leaves retained more spray when glyphosate with L-77 or Triton CS-7 was applied in all spray volumes tested. Equisetum arvense retained higher amount of spray by application of glyphosate with L-77 compared with Triton CS-7 and no surfactant treatments.

Application Methods for Enhancing Phytotoxicity of Glyphosate II. Effects of Surfactants, Spray Volumes and Simulated Rain on Herbicidal Efficacy of Glyphosate (Glyphosate의 살초효과(殺草效果) 증진(增進)을 위한 살포방법(撒布方法)에 관한 연구(硏究) II. 계면활성제(界面活性劑), 살포량(撒布量)과 강우요인(降雨要因)이 Glyphosate의 살초효과(殺草效果)에 미치는 영향(影響))

  • Field and greenhouse trials were conducted to evaluate application variables including spray volume, surfactant, and simulated rain affecting phytotoxicity of glyphosate for enhancing efficacy of postemergence herbicides. Glyphosate phytotoxicity was increased by addition of surfactants, L-77 and Triton CS-7 to glyphosate solution in Artmesia princeps and Equisetum arvense and addition of Triton CS-7 to glyphosate solution enhanced control of Trifoliurn repens. Simulated rain within 4 or 8 hours after glyphosate application reduced glyphosate phytotoxicity. However, addition of L-77 and Triton CS-7 to glyphosate solution increased glyphosate phytotoxicity reduced by simulated rain in Artmesia princeps and Trifolium repens.

  • This study was conducted to investigate the effect of Hijikia fusiforme extracts on serum lipid and liver antioxidative enzyme activities in triton-induced hyperlipidemic rats. Sprague-Dawley male rats divided into 7 groups : We injected saline to a normal group (N), saline and tween 80 to control groups (CS, CT) and tot extracts to experimental groups (CSA, CTEtOH, CTE, CTH) for 7 days and then injected triton at the last day. Serum and liver free cholesterol contents were significantly lower in hexane-treated group (CTH) than control group (CT) whereas serum HDL-cholesterol content was higher in aqueous extract group (CSA) than control group (CS). Total cholesterol and phospholipid contents in serum and liver were lower in aqueous extract group (CSA) than control group (CS). Serum and liver triglyceride contents were significantly lower in ethanol (CTEtOH) and hexane treated group (CTH) than control group (CT). Thiobarbituric acid reactive substances of liver were lower in tot extract groups (CSA, CTEtOH, CTE, CTH) than control groups (CS, CT). Superoxide dismutase activities in liver were significantly lower in aqueous extracts group (CSA) and hexane treated group (CTH) than control groups (CS, CT). Liver catalase activity was the lowest in ethylacetate extract group. These results showed that some Hijikia fusiforme extracts have reduction effect of lipid and antioxidative effect in triton-induced hyperlipidemic rats.
