狗牙根草坪杂草化学防除研究进展

Research Progress on Chemical Control of Weeds in Bermudagrass Turf

狗牙根是全球利用最为广泛的暖季型草坪草,大量用于高尔夫球场、运动场、庭院草坪与园林绿化等。杂草的入侵和竞争会导致其草坪质量下降,尤其是在建植早期,杂草问题会导致建植延迟甚至失败。对狗牙根草坪杂草化学防控研究进行总结,结果表明成熟的狗牙根草坪对大部分常用草坪除草剂有很好的耐受性,苗期狗牙根对唑草酮、二氯喹啉酸、甲酰胺磺隆等常用草坪除草剂耐受性较好。合适的除草剂或除草剂组合能较为安全高效地防除狗牙根草坪常见阔叶类、莎草类以及一年生禾本科类等杂草。

As the most widely used warm season turfgrass in the world,bermudagrass is often used in golf courses,sports fields,courtyard lawns and landscaping.The invasion and competition of weeds will lead to the decline of turf quality,especially in the early stage of establishment,weed problems will lead to the delay or even failure of establishment.This article summarized the literature researches on weed chemical control of bermudagrass turf.The results showed that mature bermudagrass turf had good tolerance to most common turf herbicides,and the bermudagrass seedling had good tolerance to common turf herbicides such as carfentrazone,quinclorac,and foramsulfuron.Suitable herbicide or herbicide combinations can safely and efficiently control common broad-leaved,sedge and annual gramineous weeds in bermudagrass.
