| Abstract/Contents: | "Field studies were conducted in 1989 and 1990 to determine the potential of Aposphaeria amaranthi as a biocontrol agent for tumble pigweed (Amaranthus albus L.) and redroot pigweed (A. retroflexus L.) Tests were designed to compare the efficacy of two different isolates, and the effects of conidial concentration and application rate on plant mortality. Seedlings at the 2-8 true-leaf stage were spray inoculated with conidial suspensions ranging from 1 X 105 conidia/ml to 6 x 106 conidia/ml with a carbon dioxide backpack sprayer a either 281 Ll/ha or 1076 L/ha or with a pump sprayer until run-off (1372 L/ha). Ninety-nine percent of tumble pigweed seedings and 73% of redroot pigweed seedlings were killed within 3 wk with the most virulent isolate when sprayed until run-off at a condial concentration of 6 X 106 conidia/ml. These results suggest that A. amaranthi may have potential as a mycoherbicide for pigweed." |
