Weed control and crop quality; the conflicting demands in organic and conventional farming systems

摘要

Weeds can effect crop quality through a number of routes. These include direct contamination by seed, fruiting bodies, buds and flower structures through to indirect contamination where the weed has provided a host to a pest or disease contaminant. The level of weed control required to achieve an acceptable level of contamination depends upon the end market and the production system, organic or conventional, used to grow the product.
