Deciding whether or not there is a brush problem, or whether a brush problem will develop within the next few years are key decisions in the development of a brushing prescription. Such decisions are currently based on a subjective evaluation of present and expected competition levels. The evaluation is generally based on field experience and background technical information. Objective techniques are needed for evaluating competition levels and describing their effects on crop seedlings to facilitate communication and to serve as guidelines for inexperienced staff.
Results from several studies in B.C. and elsewhere have contributed to our understanding of interactions between crop and non-crop vegetation. A variety of competition indices have been proposed as a basis for field assessment of competition. I will present only a few examples which I feel are most applicable to field use in B.C.
