| Abstract/Contents: | "Tri-calcium arsenate (TCA) was widely used for control of Poa annua, other annual grasses, and as an insecticide prior to 1977. Revised OSHA regulations in the middle 70's were not attainable by the then current manufacturers, and TCA became unavailable. Turf-Cal is now back in the market because of our ability to meet OSHA standards via the new flowable formulation and the efforts of turf researchers. Turf-Cal's introduction represents a unique situation in that strong demand for the product preceded its development. The use of TCA is predicated on a programmed approach for gradual replacement of Poa annua by desirable overseeded turfgrass. Although TCA has some post-emergent foliar activity, its soil and preemergent activity is more important and is maximized by timely application. TCA is selective for the warm and cool season turfgrasses presented, although not equally so between all species. TCA's selectivity is partly positional due to predominanatly shallow rooting of annual weeds but is also largely a function of differential uptake. The modes of action within the plant include uncoupling oxidative phosphorylation, effects on enzyme activation and alternation of membrane integrity. Data presented from previous investigations have shown TCA to be the most effective chemical control available for Poa annua. Safety to desirable turfgrasses has also been demonstrated when the conditions required for TCA use have been met. The next speaker will address in detail a ten-point program to ensure effective use of Turf-Cal." |
