PREVENTIVE TREATMENTS TO CONTROL WHITE GRUBS IN A FIELD-GROWN NURSERY, 2000

Toxicity of botanical formulations to nursery-infesting white grubs (Coleoptera: Scarabaeidae).

The toxicity of eight botanically based biopesticides was evaluated against third instars of the scarab larvae (Coleoptera: Scarabaeidae) Popillia japonica Newman, Rhizotrogus majalis (Razoumowsky), Anomala orientalis Waterhouse, and Cyclocephala borealis Arrow. Soil dip bioassays were used to obtain concentration-mortality data 7 d after treatment of larvae, leading to the calculation of LC50 ...

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...

Growth and Development of First-year Nursery-grown White Oak Seedlings of Individual Mother Trees

White oak (Quercus alba L.) acorns from individual mother trees at Arrowhead Seed Orchard (ASO, Milledgeville, GA), Beech Creek Seed Orchard (BSO, Murphy, NC), and Savannah River Site (SRS, Aiken,SC) were sown in December 1999 at Whitehall Experiment Forest Nursery (Athens, GA). All 6 mother trees from BSO were grafted. By early April, germination exceeded 80percent for all but six families. Fi...
