Abstract/Contents: | SUMMARY: "The performance of fluazifop-butyl against Elymus repens (L.) Gould was significantly influenced by the environmental conditions in which the plants had grown prior to treatment as follows: soil moisture deficit (greatest reduction of herbicide performance) > cool temperatures > low light intensity. The level of control under conditions in which none of these factors was reduced (so-called 'standard' conditions) was similar to that observed for 'low light' regime plants. Significant effects of environment on spray retention, foliar uptake and amounts of herbicide translocated to the roots and rhizomes were observed. The lowest rates of herbicide uptake were found with plants grown under cool conditions, the greatest amount of basipetal herbicide translocation being associated with low light intensities. Rates of herbicide de-esterification were much lower in plants grown under low light intensities, cool temperatures, or soil moisture deficits than in those plants grown under the 'standard' conditions. This result was confirmed by studies of herbicide de-esterification using cell-free leaf homogenates." |
