| Abstract/Contents: | "Goals: Develop and test concise indicators of volatilization hazard that can be used by turf managers to determine the likely degree of health hazard associated with pesticide applications.; Develop and test alternative models of turfgrass pesticide volatilization.; Progress: Two models were tested for their abilities to predict volatile pesticide fluxes from turf. The Pesticide Root Zone Model (PRZM), version 3 (Carsen et al., 1998), which combines soil and foliage volatilization models with components for pesticide leaching and runoff. The Modified Two-Compartment Model (M2CM) was used by Weed et al. (1999) to estimate alachlor dissipation from soil covered by a corn stubble. However, the model would also appear to be a reasonable approximation to pesticide volatilization from turfgrass, with compartment one consisting of the grass and thatch and compartment two made up of the underlying soil. In this case it is assumed that volatilization from the soil negligible. Model predictions and field measurements of pesticide volatilization losses are compared in Table 1. Field measurements are data from 0.2-ha turf plat experiments at the University of Massachusetts, Amherst, MA. The M2CM obviously preformed much better than PRZM. The PRZM deficiencies are particularly serious because the model may also be used to estimate runoff and leaching losses of pesticides. When applied to turf, the very high, and inaccurate volatilization from foliage removes pesticide from the turf system, limiting the chemical available for other loss mechanisms. As a result, PRZM may badly underestimate pesticide runoff and leaching." |
