Corn growers expecting trouble from the ravenous rootworm this season may be better off bypassing traditional at-planting treatments of granular insecticides, says a university entomologist. Instead, he says, consider piggybacking a liquid formulation of a labeled insecticide with nitrogen solution and banding them together at lay-by (cultivation). “ We’ve always known that lay by treatments, if properly timed, would give as good and often better control than traditional at-planting treatments,” says Dr. Marlin r 3TT y/ I i ' I ii I I '"'l T .IK AHEAD... ures Market* on Page 3, THII Road Futi Leslie Yoder RD 2 ParKesburg PA 19365 PH 215-857-3744 John Peachy RD 2 Box 73 Mifflmburg PA 17844 PH 717-966-0465 Dan Martin RD 1 Box 395 8 Black Creek Dev East Earl PA 17519 PH 215-445-7161 Star Rt.-Millersburg, Ohio 44654 Telephone 215-893-2732 Lay-by insecticide treatment controls rootworm Bergman of Purdue University. “It’s just that now, with more and more com growers banding liquid N at cultivation to improve fertilizer efficiency, we have a new and possibly better opportunity to get the job done. One provides a free ride for the other.” In the Corn Belt and mid- Atlantic states, where rootworm infestations have been most pronounced, larvae usually begin feeding in early to mid-June and continue up until late July. Most rootworm insecticides applied at planting today remain active in the soil up to 12 weeks, usually long enough to hold larvae in check until mid-summer, when they stop feeding. However, Bergman says, several un controllable environmental con ditions including microbial ac tivity in the soil or heavy rains could cause at-plantmg treatments to lose their punch before larvae finish feasting on plant roots. “In recent years, many com growers have been disappointed with the performance of their at Why You Should Use Silo Sym On Baled Hay: allows you to bale tougher a definite hedge against the weather saves more leaves higher protein con tent enhances palat ability of hay easy to apply with Gandy Applicator Silo Sym can also be applied on haylage SPECIAL EARLY ORDER PRICES IN EFFECT NOW.

It’s good in surance, and it gives you better cashflow.” The key to this control program’s success, says Bergman, is to apply the msecticide/fertilizer tank mix shortly before larvae start feeding, usually not later than the first week of June.
