Here’s the new issue of the Wisconsin Crop Manager.

• New Corn and Soybean Herbicides for 2008
  This season brings several new corn and soybean herbicides to the market. While some of these herbicides are marketed specifically for use in herbicide-resistant crops, others can also be used to reduce the risk of early-season weed competition. All but one of these herbicides contain active ingredients that have been previously marketed.
• Orion: Another New Wheat Herbicide
  In addition to the wheat herbicides reviewed in the last issue, Orion (Syngenta) has recently received its registration. Orion is a postemergence broadleaf herbicide for wheat, barley and oats and contains the ingredients florasulam and MCPA.
• Early and Reduced Rate Applications of Foliar Fungicides for Wheat
  In the past few weeks, there has been much discussion among Extension Specialists in the U.S. regarding recommendations for early and reduced rate applications of foliar fungicides for wheat. Based on results around the U.S., we recommend that growers actively scout their fields for the presence of wheat diseases before making a foliar fungicide decision.

• Early Season Wheat Stand and Yield Assessment
  Near record wheat commodity prices coupled with increasing input costs for corn and soybean prompted many Wisconsin growers to increase their wheat acres in 2007. As the ice and snow begins to dissipate over the next few weeks it is critical that we accurately assess the winter injury to the wheat crop and make the appropriate management decisions regarding the wheat stand, nitrogen timing, and yield potential.
• Seed Treatments Containing Lindane: Time is Running Out!
  EPA issued final orders in 2006 cancelling the registrations of all products containing the pesticide lindane, including those products used as a seed treatment on grain. Although end-use products containing lindane no longer can enter the channels of trade, end users (i.e., co-ops, applicators, etc.) have until October 1, 2009 to use existing products already in the channels of trade.
