'g—Lancaster Farming, Saturday, February 23, 1963 Corn Clinic At New Holland, “Today’s Answer to Yester day’s'Problems,” was the topic ot discussion at the Carden Spot Young Adult Farmers’ meeting last Tuesday evening. Mr. Phillip Koch, Area Pield man for Geigy Agricultural Chemicals, discussed the chem ical weed control in corn pro duction He stated that effect ive weed control is one of the most essential needs of every farmer who grows corn Here are some questions that were answered. How has modern chemical weed control been ac cepted among the farmers who pioduce top yields’ How do they use herbicides on their own farms’ What ai e the ben efits’ Why is effective chemical weed control so important for improving efficiency and pi ofit in com pi eduction It was stated that some of the newer herbicides used to control weed in lows with an application at planting, before ■weeds aie up Another piactice widely used is an application after planting, any time befoie weeds aie 1% in high. Weed killers can be sprayed the day after planting or at any time before weeds and grasses are IVz in high The herbicide is absorbed by weed seedlings through foliage and roots. Koch stated that good weed control is largely dependent up on these conditions; 1 Proper rate of application according to soil type; 2. Uniform distribu tion on soil surface, 3. Proper calibration of equipment at re commended rates, 4. Adequate moisture is needed to move herbicide into soil where it can be absorbed by weed roots; C For granules, good seedbed preparation that is smooth and compact, free of clods, is espec ially important.

Koch suggest ed the following treatment: 1. Make first broadcast appli cations to quackgrass in the spring, three weeks before plowing. 2 After planting corn make a second application for control of annual broadlea? weeds and grasses and to finish off any persistent quackgrass. It was recommended that corn should follow corn when these special treatments of higher-than normal dosage rat es are used. Maximum sunlight provides conditions for faster weed kill ing and warm temperatures re sult in taster weed growth and more rapid absorption of herbi cide by the weed Rain is nec essary to move the herbicide into the weed root zone. Ade quate moisture at the tune ot planting or shoitly afterwards, dissolves the herbicide and dis perses it lapidly through the soil making it readily available for absorption by weed roots Under high soil moisture con ditions, weeds tend to germin ate nearer the surface where they aie easily killed. In a dry spring, the farmer must cultivate as soon as weeds appear to move the chemical into the root zone. Rates of application, said Mr. Koch, should be carefully fol lowed from the label directions. Because some chemicals re main in the soil to work for you all season long, observes these four simples rules: 1. Do not use more herbicide than is recommended for your soil type. 2. To minimize possible inj ury to wheat or barley, plow or work the soil well. 3 Corn should follow corn when higher-than normal dos age rates are *used 4 Do not follow treated corn with sugar beets or vegetables m rotation.
