10.17 GOLF COURSE MANAGEMENT 67 thinking about turfgrass insects, a consider- ably less catchy but more fitting lyric might have been, "It's good to be the windshield; try not to be the bug." Matt Giese, M.S., is the Midwest field technical manager for turf and landscape at Syngenta and a 24-year veteran of the turfgrass industry. available treatment options, the program is ready to be implemented. Mapping and scouting histories will give the turfgrass man - ager clues about where and when to scout for the pest. Insect life stages provide information about when to target applications. Establish - ing a plan for implementation is just as critical as the program itself. A number of indicators can be used to determine when treatments should be applied to control or prevent insect infestations: turf response; growing degree day thresholds (numerous GDD calculators are available online; see Page 64 for a list of some); plant phenological indicators such as forsythia bloom; sampling population num - bers; or a combination of factors. No mat- ter which indicator signals action should be taken, proper planning and communication are essential to initiating the program in a timely manner. For recurring pests such as annual bluegrass weevil or mole crickets, it's important to evaluate all facets of an insect control program to improve and adjust the program throughout the season and in sub - sequent years. Assessing how well the program worked at the end of the infestation or season can provide a valuable opportunity for making adjustments to product selection and timing and even re-establishing damage thresholds. Additionally, a program approach should also account for time and money required and then be discussed with committee and/ or board members. These elements are use - ful in determining what changes, if any, should be made before the next period of in - sect activity. Final considerations Although every insect pest may not need a specific agronomic program, superinten - dents will certainly find it worthwhile to build a foundation of healthy turf, to have documented past pest occurrences to help simplify time of application, and to know the most effective practices and products. Un - derstanding insect life cycles and targeting development stages that are most susceptible with the appropriate insecticide mode of ac - tivity and mode of action are paramount to any program's success. Armed with this information, a superin - tendent can customize a plan of action for the golf course that is achievable and cer - tainly increases the likelihood of a success- ful outcome.
