Show WHITE TOP CAUSES HEAVY CEOP LOSS ON UTAH FARMS Utah farmer.j are facing a serious w cd problem. At present they aie suffering a loes of approximately $2,000,000 a year and tlha tell is becoming be-coming greater with each succeeding succeed-ing year-, w-arns Professor J. C. Ho-gens.ri, Ho-gens.ri, extension agi'oncmlet cf the Ub h Scat" Agricultural colloge. Thii icss is caused by the weeds occupying th; ground that should be growing productive crops. They rob this so 1 cf plant food and moisture mois-ture which crops should receive, thus causing a lower yield of inferior in-ferior quality. They create aa ever increasing amount cf work to keep them in check. Probably the wor.t weed in Utah is) whitri top, a perennial which multiplies both by :ieed and by underground un-derground root stocks. Every inch of root stock no matter whether attached at-tached to the plant or cut off will produce a new thrifty plant, Pro-fesior Pro-fesior HogenexDn points out. Th 'r.ei are two ways of handling thi? white top. The method to be used thculd be determined by the size of the patch. If the patch is larga, cultivate; while if it is small, use a chemical spray. Thorough cultivation means that the operation should be done suf-fiently suf-fiently often to prevent new growth from appearing above the surface of the ground, begging in the spring and continuing u.itil the end of the growing teason in th? fall. During Dur-ing the year the patch should be watered frequently to keep the plants in the best growing condition. This will exhaust the food supply stored in this roots much more quickly than will be the caee if the plants are allowed al-lowed to remain dry during the growing season. When the food supply sup-ply stored in the rcots is exhausted and no ec,f is allowed to grow so that more food can be manufactured, manufactur-ed, the plants' die. If fft.e we'"d patch is small, then '-pray ;rufficiently cftenl during thf growing season with a solution of calcium chlorate using Sjout three peuleds cf the chlorate per square rod of weeds to keep the tcps killed down. Where the patches are-large are-large th;s method is altogether too expensive. |
