双酯灵的除草活性及对草坪草的安全性研究

Study on the Herbicidal Activity of Shuangzhiling and their Safety to Turf

双酯灵是西安近代化学研究所创制的新除草剂品种 ,初步试验表明 :双酯灵以 75 0～15 0 0 g/hm2 的用量对独行菜、泥湖菜、夏至草、反枝苋、马齿苋等阔叶杂草有良好的除草活性 ,但对禾本科杂草基本无效。在推荐剂量范围内对北方常见草坪草早熟禾、黑麦草、高羊茅基本安全 ,秋季使用优于春季使用。

Shuangzhiling is a new turf hebicide developed by Xi'an Modern Chemistry Institute.The preliminary result of trials showed that had good efficacy against broad-leaved weeds,such as purslane,amaranthus retroflexas,at the rate of 2500-6000g/ hm 2.Shuangzhiling did not show any efficacy to grasses.The rate recommended for turf was 750-1500g/hm 2,which was safe to turf,such as Merit,Accent and Crossfire.The best period to be applied is in the autumn.
