PREVENTIVE CONTROL OF WHITE GRUBS ON A GOLF COURSE ROUGH, 2008

The Maximum Throughput on a Golf Course

W e develop stochastic models to help manage the pace of play on a conventional 18-hole golf course. These models are for group play on each of the standard hole types: par-3, par-4, and par-5. These models include the realistic feature that k 2 groups can be playing at the same time on a par-k hole, but with precedence constraints. We also consider par-3 holes with a “wave-up” rule, which allo...

Identifying and Managing White Grubs in Turf

White grubs are the larval stage of several scarab beetle species that feed on grass roots causing wide variation in damage. Last fall, we saw an abundance of white grub damage around Vermont, so it is likely, that we will see more damage this spring and summer. However, grub damage can vary significantly from year to year and we know that turf that receives adequate water and has a healthy roo...

Maximizing ‘Cimarron’ Little Bluestem Establishment as Secondary Rough for a Golf Course

Native grasses are an important design component in secondary roughs of golf courses due to minimal maintenance requirements and aesthetics. However, problems with seed germination and subsequent establishment limit their use. Two 2-year studies on ‘Cimarron’ little bluestem were conducted in 2000 and 2002 at Mississippi State University. In each study, seed was planted at five rates: 12.7, 25....

Effects of spring imidacloprid application for white grub control on parasitism of Japanese beetle (Coleoptera: Scarabaeidae) by Tiphia vernalis (Hymenoptera: Tiphiidae).

Imidacloprid, a relatively long residual neonicotinoid soil insecticide, is often applied to lawns and golf courses in spring for preventive control of root-feeding white grubs. We evaluated effects of such applications on spring parasitism of the overwintered third-instar Japanese beetle, Popillia japonica Newman, by Tiphia vernalis Rohwer, an introduced solitary ectoparasitoid. Natural rates ...
