dc.description.abstract | Wild radish is a major weed in winter grain crops in Australia. This weed is poorly controlled by glufosinate. Therefore, factors influencing glufosinate efficacy in this species were examined. Dose–response studies conducted with three populations of wild radish collected from different parts of Australia and one from Europe showed poor control of all populations by glufosinate under Australian winter conditions. Studies conducted in controlled environmental chambers under night/day temperatures of 5/10, 15/20, and 20/25 C and various light intensities demonstrated that wild radish grown under cooler temperatures of 5/10 C were poorly controlled with 1,200 g ai ha⁻¹ glufosinate when the same rate was sufficient to cause 100% mortality under 15/20 and 20/25 C. Light intensity did not significantly influence glufosinate activity at low temperatures. However, under warm temperatures of 20/25 C, glufosinate efficacy was enhanced with low light intensities. Experiments examining absorption and translocation of glufosinate showed that temperature did not have a significant effect on absorption of glufosinate. However, basipetal translocation of glufosinate was greatly increased by higher temperatures. Therefore, the poor control of wild radish by glufosinate at low temperatures is probably because of reduced accumulation of glufosinate in the meristematic regions of the plant. | - |
