摘要

Aesthetic and economic characteristics of different turfgrass fertility and pesticide programs were compared in an effort to provide a framework for lawn care professionals to evaluate, market, and implement alternative management strategies. Programs included a consumer program (CP), an integrated pest management program (IPMP), a natural organic program (NOP), and a no-input program (NIP). All programs significantly improved visual appearance compared with the NIP, and although the IPMP and CP consistently had the highest ratings, the NOP produced lawns of similar quality on the majority of rating dates. The NOP also resulted in canopy greenness levels similar to or significantly greater than those provided by the IPMP and CP on most dates. Aside from the NIP, the lowest total maintenance costs were associated with the IPMP during both study years. Although the NOP was the most expensive program when white grub (Coleoptera: Scarabaeidae) populations exceeded treatment thresholds, it was less expensive than the CP when white grubs were below thresholds. Incorporation of scouting into different fertility and pesticide programs resulted in short-term economic benefits without significantly compromising turfgrass aesthetic quality.
