Impact of Timing and Frequency of In-Row Cultivation for Weed Control in Dry Bean (Phaseolus vulgaris)

摘要

Effectiveness of rotary hoeing with cultivation and comparison of an in-row cultivator with a sandard row-crop cultivator were determined in dry edible bean. The effectiveness of in-row cultivation conducted at various timings and frequencies was examined. The in-row cultivator was more effective in reducing weed populations than the standard cultivator, although at least two me- chanical weeding operations were needed to reduce weed populations to levels of the herbicide check (EPTC [S-ethyl dipropyl carbamothioate] plus ethalfluralin).
