Abstract
Efficacy of allelopathic crop water extracts to control weeds can be enhanced by integrating them with other phytotoxins. The effects of allelopathic crop water extracts and their combinations along with lower rates of Atlantis 3.6 WG were studied to control weeds in rainfed wheat through field experimentation during 2009-2010 and 2010-2011. Treatments included weedy check, hand weeding, Atlantis 3.6 WG @ 14.4 g a.i. ha -1 , sorghum water extract, sunflower water extract, sorghum + sunflower water extract and combinations of sorghum + sunflower water extracts with 25, 50 and 75% rates of Atlantis 3.6 WG arranged in randomized complete block design. Results revealed that combination of allelopathic extracts with lower rates of herbicide decreased weed density, fresh and dry weights by 42-70%, 38-62% and 37-63%, respectively. Atlantis 3.6 WG @ 14.4 g a.i. ha -1 reduced these parameters by 59-66%, 52-53% and 52-56%. The maximum numbers of fertile tillers, number of grains spike -1 and grain yield were recorded from hand weeding. Statistically, similar yields were obtained from allelopathic water extracts combined with 50-75% rates of herbicide and full dose of herbicide. Relatively lower wheat grain yields were recorded during second year compared with first due to moisture stress. The maximum net benefits were achieved from sorghum and sunflower water extracts mixed with 75% dose of Atlantis 3.6 WG followed by mixture of allelopathic extracts with 50% herbicide and recommended rates of Atlantis 3.6 WG (14.4 g a.i. ha -1 ). Marginal analysis exhibited dominance of all treatments except combination of extracts with lower doses of herbicides. The study concluded that sorghum and sunflower water extracts can be used in combination with 50-75% rates of Atlantis 3.6 WG to control weeds economically in wheat crop under rainfed conditions.
