Researches on weed control in vegetable and fruits are reviewed in the aspects of technical dissemination of research results and problems to be solved for the establishment of integrated weed control measures. The future researches in relation to the possible changes of cultivation pattern in horticultural crops are also discussed. The current situation of weed control in horticulture in general is classed as a primitive stage comparing to other food crops and is well behind of other advanced countries. It is strongly suggested that only steady and extensive researches in this field will produce a significant contribution to the minimization of labor cost in horticultural crop production.
