Researchers Seeking New Ways To Control Nursery Tree Pest WOOSTER, Ohio From soil-applied systemic insecti cides to tree guards, Ohio State University entomologists are looking tor ways to control one of the most economically dam aging insect pests in the nursery industry in Ohio and neighbor ing states. The white pine weevil, a North American native that at tacks pine and spruce trees, has become more problematic over the past several years, threaten ing tree nurseries in Ohio and timber industries in states such as Pennsylvania and Michigan. “The white pine weevil has become the No. 1 pest encoun tered by Ohio Department of Agriculture nursery inspectors,” said Dan Herms, an Ohio State entomologist with the Ohio Ag ricultural Research and Devel opment Center. “Historically it’s been an important pest for the timber and Christmas tree industries in eastern Ohio, but the last couple of years it’s really taken off throughout the state, hop-scotching across ornamen tal landscapes and nurseries.” CSifCJ* See pages 823-835 We Now Accept Visa Lancaster Farming* 1 E Mam St Ephrata, Pa 17522 717-394-3047 or Lititz 717-626-1164 FAX 717-733-6058 Men , Tues , Wed & Fn 8 a m. to 5 p.m Thurs. 7 a.m. to 5 p m OFFICE HOURS.

The larvae hatch and feefl on the inside of the tree, causing die back. “The insect doesn’t kill the tree, but destroys the symmetri cal growth pattern that conifers exhibit. The tree forms multiple shoots, looking bushy and asym metrical,” said Herms. “It costs the nursery industry a tremen dous amount of money because companies can’t sell the tree until it re-establishes itself. A single insect attack can elimi nate two to four years of growth. Insect feeding also reduces the quality of trees as saw logs.” Herms said the white pine weevil is a threat to nursery and timber industries because the insect is not so easy to control. “Methods for control, mainly insecticides, are no longer avail able, either because the labels have been cancelled by the EPA (Environmental Protection Agency) or it’s not economically feasible for companies to carry CLASSIFIED AD ORDER BLANK £ LANCASTER FARMING J) V P.O Box 609, Ephmta, PA 17522 i NOTE: Please do not use this form for Mail Box Market Ads, see instructions with Mailbox Markets.

Researchers are currently studying systemic insecticides chemicals applied to the soil at the base of the tree that are ef fectively taken up by the plant and protect it from larval feed ing. “Other insecticides used arc extremely toxic, but the presence on the market of non-toxic sys temic insecticides is a new devel opment,” said Hcrms “The systemic insecticides otter the advantage ot being easier to time their application accu rately.
