摘要
将啶嘧磺隆和三氟啶磺隆钠盐用于马尼拉草坪上防除香附子,结果表明,啶嘧磺隆每667 m2有效成分用药量为1.3 g时,对香附子的防效为84.8%,当用药量为5 g时,防效可达到98.8%;三氟啶磺隆钠盐每667 m2有效成分用药量为1.5 g时,对香附子的防效为90.7%,当用药量在6 g以上时,防效则为100%;而对照药剂MCPA-Na每667 m2有效成分用药量为56 g时,防效只有49.4%。同时,试验结果表明两种磺酰脲类除草剂对马尼拉草坪安全。
The study on the Rhizoma cyperi （Cyperus rotundus L.） in Manilagrass turfgrass with two sulfonylureas herbicide showed that the control effect of 25% flazasulfuron was 84.8% at the dosage of 5 g per 667 m2, and reached 98.8% at the dosage of 20 g per 667 m2. The control effect of 75% Trifloxysulfuron was 90.7% at the dosage of 2 g per 667 m2, and reached 100% at the dosage of 8 g per 667 m2. The control effect of 56% MCPA-Na was 49.4% at the dosage of 100 g per 667 m2.
