Abstract

Integrated pest management has been implemented as a general practice by EU legislation. As weed control actually is the most important crop protection measure in maize for Western Europe, the new legislation will have its impact. The question is of course which systems can be successfully implemented in practice with respect to labour efficiency and economical parameters. During 3 successive growing seasons (2007, 2008, 2009) weed control in maize was evaluated, the main focus was put on different techniques of integrated weed control and was compared with chemical weed control. Additionally, during 4 successive growing seasons (2011, 2012, 2013 and 2014) two objects based on integrated weed control and two objects based on mechanical weed control were compared to about twenty different objects of conventional chemical weed control. One of the objects based on mechanical weed control consisted of treatment with the flex-tine harrow before and after emergence in combination with chemical weed control at a reduced rate in 3-4 leave stage. The second one consisted of broadcast mechanical treatments before and after emergence followed by a final in-row application of herbicides and an inter-row cultivation at 6-7(8) leave stage. All trials were conducted on the Experimental farm of Bottelare HoGent-UGent on a sandy loam soil. Maize was growing in 1/3 crop rotation. The effect on weed growth as well as the economic impact of the different applications was evaluated. Combining chemical and mechanical weed control is a possible option in conventional farming but the disadvantages must be taken into account. A better planned weed control based on the real present weed-population in combination with a carefully thought-out choice of herbicides should also be considered as an IPM--approach.

玉米杂草综合防治。
有害生物综合治理已被欧盟立法作为一种普遍做法加以实施。由于杂草控制实际上是西欧最重要的玉米作物保护措施,新立法将产生影响。当然,问题是在劳动效率和经济参数方面,哪些系统可以在实践中成功实施。在连续3个生长季(2007、2008、2009)对玉米的杂草防治进行了评价,重点评价了不同的综合防治技术,并与化学防治进行了比较。在连续4个生长季节(2011年、2012年、2013年和2014年),将2个综合除草目标和2个机械除草目标与约20种不同的常规化学除草目标进行比较。机械除草的目标之一是在出苗期前后用柔时耙进行处理,并在3-4叶期减少化学除草率。第二种方法是在出苗期前后进行撒播机械处理,最后在行施用除草剂,并在6-7(8)叶期进行行间栽培。所有试验均在沙质壤土上的波特雷HoGent-UGent试验农场进行。玉米以三分之一的轮作方式生长。评价了不同施用方式对杂草生长的影响及经济效益。在传统农业中,化学和机械结合控制杂草是一种可能的选择,但必须考虑到缺点。根据现有杂草种群的实际情况,结合仔细考虑除草剂的选择,更好地规划杂草控制也应被视为一种IPM方法。
