NEW HAMPSHIRE PLANT GROWERS ASSOCIATION |UNE AND |ULY I 998 w.re have a special name for the trees that come from our farms—^ArcticMist.™ When you order

ArcticMist,^^' you are not just buying a tree, but all of the time, attention, and care—from seedling to shipping— that goes into creating a safe, healthy, and

beautiful Christmas tree.

We plant from seed to achie\ e maximum ciualirs

control. All ArcticMistT^^' trees are heavily needled and

have dense conical shapes. Their lovely blue color, rich

fragrance, and good needle retention make them ideal

Christmas trees. Fraser, balsam, white spmce, and pine

(white, scotch, and red) are available. In addition, we

are introducing fralsam, a fraser-balsam cross. Wreaths are

also available.

Since our farms are in New Hampshire and

Vemiont, we harvest our trees later in the season than

many other growers. We also do everything we can to

minimize moisnire loss after harvest and during shipping.

^'ou can order the number of trees that is right for

\ t)u— from 25 to a trailer load. We can arrange shipping or you may pick up the trees yourself We respect your schedule and guarantee on time delivery. Our trees ani\ e

individually wrapped and ready for sale. All you need to

do is remove the wrappers and set the trees out—no

broken branches, no last minute trimming.

THE PL A NTSM A N Control of Black Vine Weevil in Potted Nursery Plants

DR.. STANLEY R. SWIER, ALAN ROLLINS, RACHAEL LAMARCHE, AND MEGGAN HODGSON

C'ontrol of the black vine weevil is very difficult. The weevil emerges from overwintering sites in spring and seeks out host plants. The adult chews on leaves, causing characteristic notches. These notches are particularly common on taxus and rhododendron. The larvae feed on the roots, reducing growth and predisposing the plant to winter kill. If the plants are kept warm, larvae Treatment will feed during the win- ter. Since the adult is active all summer, con- trolling the adult re- quires frequent sprays to the foliage through- out the growing season.

A better strategy is to target the larvae which do the most severe dam- age. We investigated some promising chemical and biological controls for larval control in 1997. Van Berkum's Nursery generously provided us with 160 potted plants (Bridget bloom, Heucherella alba) at no cost. FMC Corp. provided financial support for labor. Nema- todes were obtained from The Green Spot. The black vine weevil eggs were obtained from the Con- necticut Agricultural Experiment Station in Windsor. The trial was conducted at the UNH Kingman Farm. Ten replications of six treatments were applied to seven-inch pots. Talstar granules were incorporated into the media based on the bulk density (0.24 g/cc). Merit was applied according to pot size. Both these granules were incorporated into the pots on June 10 and the plants repotted. Surface applications of Tal- star Flowable and Lorsban granules were done on June 30. The first application of nematodes was ap- plied July 13 and repeated every two weeks for a to- tal of four applications. We chose the nematode Heterorhabditis bacteriophora because of its ability to ac- tively seek out prey in soil. The liquid formulations and nematodes were poured over the surface of the — MEMBER PROFILE
