除草剂在农业中的需求将会增加，其在世界各地的使用也越来越多。随着数以百万计的人从农村向城市迁移，印度、中国、孟加拉国等许多发展中国家面临着手工除草工人短缺的问题。在这些国家，除草剂比手工除草更便宜，也更容易获得。不可避免的是，除草剂在世界农业中的使用量将会增加，这不仅是因为数百万人离开农村地区，造成手工播种机短缺，而且还因为需要提高作物产量。人工除草从来都不是一种非常有效的杂草控制方法，往往进行得太晚，而且不够频繁。在世界许多地区，为了改善环境条件，除草剂正越来越多地被用来取代耕作。与耕作相比，除草剂的使用减少了侵蚀、燃料消耗、温室气体排放和养分流失，并节约了水资源。本文重点介绍了除草剂的使用现状及其在全球农业中的应用情况。J.孟加拉Agril.大学。2015年6月13日(1)：19-30
The demand of herbicide in agriculture is going to be increased and its use is increasingly being adopted around the world. Many developing countries like India, China, Bangladesh are facing shortages of workers for hand weeding crop fields as millions of people are moving to urban from rural areas. In these countries, herbicides are cheaper and more readily available than labor for hand weeding. It is inevitable that, herbicide use will increase in world agriculture, not only because millions of people are leaving rural areas, creating shortages of hand weeders, but also the need to increase crop yields. Hand weeding has never been a very efficient method of weed control often performed too late and not frequently enough. In many parts of the world, herbicides are being increasingly used to replace tillage in order to improve environmental conditions. In comparison with tillage, herbicide use reduces erosion, fuel use, greenhouse gas emissions and nutrient run-off and conserves water. This review article focuses on the status of using herbicides and its adoption in global agriculture. J. Bangladesh Agril. Univ. 13(1): 19-30, June 2015
