- Abstract
Conservation tillage methods have become increasingly popular in World due to increasing fuel cost and environment-conscious. But, the sustainability of conservation tillage systems depends on the development of economical and effective weed management systems. Poor understanding of weed population dynamics and lack of suitable control alternatives often result in insufficient weed control and increased herbicide use in conservation tillage systems. The objective of this paper is to review the researches on weed population dynamics and control in conservation tillage systems. The studies showed that successful weed control in conservation tillage systems needs accurately identifying weeds. Conservation tillage systems resulted in shifts in weed populations from annuals to perennials. However, reports of weed species shifts have been inconsistent. The rotations and cover crops were considered to be essential components in reducing weed problems and the dependence on herbicide usage in conservation tillage systems. The availability of herbicides suitable for control of a wide range of dicotyledonous and monocotyledonous weed species was a paramount requirement for any conservation tillage system. However, the use of herbicides with the same mode of action (belonging to the same herbicide group) year after year can result in weeds that are resistant to those herbicides. Consequently, certain types of weeds are more common in conservation tillage systems and may require special consideration.
