我地水稻秧田常发性的主要杂草是稗草,其次是莎草,80年代及以前均是用除草醚防除,防效不理想。为了有效控制秧田主要杂草,我们于90年代初引进禾大壮防除秧田稗草,1993年又用禾大壮与多效唑混用进行防除试验,既取得了防除杂草的理想效果,又促进了水稻壮秧的形成。 一、材料与方法 (一)供试药剂:(1)96％禾大壮乳油(英国卜内门公司产):(2)扫茀特乳油(瑞士汽巴嘉基公司产);(3)50％神锄可湿性粉剂(昆山化工厂产);(4)15％多效唑可湿性粉剂(建湖农药厂产)。
The main weedy rice in paddy field was barnyardgrass, followed by sedge. In the 1980s and before, weeding herbicide was used to control weeds and the control effect was not satisfactory. In order to effectively control the main weed seedling, we introduced in the early 90’s Wo Zhuang strong barnyard grass seedling control in 1993 with the Wo strong Zhuang and mixed with paclobutrazol control trials, both to achieve the desired effect of weed control, but also to promote rice Strong seedling formation. First, the materials and methods (a) for the test agents: (1) 96% Wo big strong EC (British Bu Neimeng company production): (2) sweat EC special cream (Swiss Ciba-based company) 50% God hoe WP (Kunshan Chemical Plant); (4) 15% Paclobutrazol WP (Jianhu Pesticide Factory).
