About 20 percent "rom New England to the of the corn acreage of Mid-West, says Nathan L. Pennsylvania is now infested Hartwig, weed scientist at with nutsedge, he claims, '.-'he Pennsylvania State and the figure is increasing P. L ROHRER & BRO., INC. annually. Strangely, nut sedge and quackgrass are never found growing together. Extensive experiments by Dr. Hartwig and associates have found four herbicides effective in controlling nutsedge-Sutan, Eradicane (a new eptam formulation, AAtrex, and a combination of AAtrex and Lasso. These herbicides will also control most annual weeds including witchgrass, crabgrass, fall panicum, and giant foxtail. One year’s treatment of cornfields will seldom remove nutsedge (nut grass), the studies have found. Large numbers of small underground bulbs, much like onions, can remain dormant in the soil for a number of years. This means herbicides must be used for several years to gain complete control of yellow nutsedge. Dr. Hartwig says Sutan and Eradicane are the most consistent herbicides of those recommended. -Sutan and Eradicane should be applied before planting com and should be worked into the soil immediately since they are volatile. Avoid applying Sutan or Eradicane to damp soil since as much as 40 per cent can be lost in 20 minutes after application. Use oae-half to two-thirds gallon per acre of Sutan, plus AAtrex SOW at a rate of one and one-quarter pounds per acre, or AAtrex 4L at the rate of 1 quart per acre. Work this into the soil twice by disking, the second time at a 45 degree angle to the first. Eradicane should be applied at a rate of one-half gallon per acre. Another effective treat ment is to use AAtrex SOW at 2.5 pounds per acre, or AAtrex 4L at 2 quarts per John J. Hess, 11, Inc. Ph. 442-4632 Paradise West Willow Formers Assn., Inc. Ph-464-3431 West Willow acre, right before planting. Work this into the soil with one disking. After the sur viving nutsedge reaches a height of 6 to 8 inches, treat again with one and one quarter to two and one-half pounds of AAtrex SOW or 1 to 2 quarts of AAtrex 4L per acre. This should be applied with a non-toxic oil or other “sticker.” A fourth effective treat ment is AAtrex SOW at one and one-quarter pounds per acre, or AAtrex 4L at 1 quart per acre, plus Lasso at 2 quarts per acre. As with Sutan, this herbicide should be applied before planting com. This treatment can be worked into the soil up to a week after application.

URI/VA HEIFER CHOW More and more local dairymen are proving that a small extra investment in heifer feeding can pay off when heifers freshen and begin contributing to the milk check. And research has proved that heifers which produce well in the first lactation continue to be high producers over a longer milking life than average cows. Purina* Heifer Chow* has been developed to help you grow big heifers fast, conveniently and at low cost. Heifer Chow is a palatable coarse 14 per cent protein ration, fortified with vitamins and minerals to stimulate fast, solid heifer growth. To build low-cost growth, you need feed only 3 pounds of Heifer Chow per heifer per day if your legume forages are of good quality. For best results, start your heifers on the Purina heifer growing program at six months of age until 90 days before freshening when they’ll be fed on the basis of their condition and on the quality of your forage. Drop in soon and pick up a copy of our Purina Heifer Growing Program folder. It explains the program to follow for fast growing, early-freshening heifers at low cost. *Reg Trademark—Ralston Purina Co Ira B. Landis Wenger's Feed Mill Inc.
