چکیده

به منظور بررسی کارآیی برخی از علف­کش­ها بر کنترل علف ­­هرز اویارسلام زرد در چمن برموداگراس (Cynodon dactylon)، آزمایشی در سال 1393 در فضای سبز منطقه‏ چهار شهر اهواز انجام گرفت. آزمایش در قالب طرح بلوک­های کامل تصادفی با شش تیمار و چهار تکرار انجام شد. تیمارهای آزمایش شامل: 40 گرم ماده مؤثره متسولورون متیل + سولفوسولفورون (توتال WG80%) در هکتار، دو لیتر اکسادیازینون (رونستار EC12%) در هکتار، یک لیتر کلتودیم (سلکت سوپرEC12%) در هکتار، دو لیتر سیکلوکسیدیم (فوکوس EC10%) در هکتار، 175 گرم نیکوسولفورون+ریمسولفورون (اولتیما EC75%) در هکتار و   شاهد عدم کنترل بودند. علف­کش‌ها یک‏ بار در ابتدای رویش علف­ ­هرز و دو باردیگر، با فاصله زمانی یک ماه تکرار شدند. نتایج نشان داد که تیمارها، اثر معنی­داری بر تراکم و وزن خشک اویارسلام زرد داشتند. سه علف­کش رونستار، فوکوس و سلکت­سوپر به ترتیب با میانگین تأثیر 4/95، 42/93 و 9/90 درصد کنترل در سه مرحله سم­پاشی نسبت به شاهد عدم کنترل، تیمارهای برتر بودند. کاربرد علف­کش­های توتال، اولتیما و رونستار، به ترتیب باعث خسارت 3/22، 56/19 و 58/13 درصدی به چمن شدند. سایر علف­کش­ها، تأثیر سوء کمتری بر چمن برموداگراس داشتند. در مجموع و از میان علف‏کش‏ها، فوکوس به دلیل کنترل مناسب اویارسلام زرد و کمتر بودن اثرات سوء آن نسبت به سایر علف‏کش‏ها بر چمن آفریقایی (برموداگراس)، مناسب‏تر از سایر علف‌کش‌ها بود و بنابراین، قابل توصیه می‏باشد.

چکیده [English]

To evaluate the efficacy of some herbicides in the control of yellow nutsedge (Cyperus esculenthus L.) in Bermudagrass, an experiment was conducted in green zone of Ahwaz in 2014. Experiment was conducted in a randomized complete block design with 6 treatments and 4 replications. The treatments consisted of application of metsulfuron-methyl+sulfusulfuron (Total), oxadiazon (Ronstar), clethodim (Select Super), cycloxydim (Focus), nicosulfuron+rimsulfuron (Ultima) and untreated check. Herbicides were applied at the beginning of weed emergence and repeated two more times with one month intervals. The results showed that weed treatments had significant effects on the density and dry weight of yellow nutsedge. Ronstar, Focus, and Select Super, with the mean of 95.4%, 93.42% and 90.9% weed control compared to control treatment, respectively, were the best treatments. Application of Total, Ultima and Ronstar herbicides caused 22.23%, 19.56% and 13.58% damage to yellow nutsedge, respectively. Other herbicides had less adverse effects on Bermudagrass. Total and Focus were the most suitable herbicides because of its proper control on yellow nutsedge and its low level of adverse effects on African grass (Bermudagrass) than other herbicides and therefore, it is recommended.
