dc.description.abstractThe main objective of this investigation was to determine if satisfactory weed control in vegetable crops (scallions) could be achieved and overall chemical use reduced by very repeated low dose applications of contact and contact residuals herbicides. The trials showed that scallion crops could tolerate certain post-emergence herbicides better than weed populations earlier in their life cycle provided the first true leaf of the crop had reached 1.5- 2cm in length . Various combinations or cocktails of herbicides of cyanazine, oxyfourfen, ioxynil and gesagard were tested both at Kinsealy and in several commercial locations in Co. Dublin at very low rates varying from 17 to 70g/ha and these were compared with current standard post-emergence recommendation of single rate ioxynil at 0.4-0.7 kg/ha. Each of the cocktail combinations apart from ioxynil and cyanazine produced highly satisfactory weed control when repeated at 7-12day intervals commencing when the first true leaf averaged 2cms long, over a wide range of conditions. The most effective and satisfactory weed control was achieved from either the oxyflourfen (17- 35g/ha) plus cyanazine (35-70g/ha) or the ioxynil(17-35g/ha) plus gesagard (17-35g/ha) combinations. These matched the weed control given by the standard recommended treatment of ioxynil with the advantage of a reduction of up to 50% chemical usage.en_GB
