Chemical phytotoxicity testing facility for warm-season turfgrasses

The registration of new agricultural chemicals (particularly herbicides) for turf use requires supporting data on their possible phytotoxic effects across a representative range of turfgrass species and cultivars. This process has been streamlined by the establishment of dedicated phytotoxicity testing site. This facility has enabled phytotoxicity screening of new chemicals to be conducted more quickly, thoroughly and economically than the previous piecemeal ad hoc approach. During the three years of this project, 39 products were screened on the site.
