Show . i clover. It makes its growth' early in the spring and 'flowers in the latter part of April or early May, depending upon the season and altitude. Occurrence White top was introduced into the United States about 50 years ago and is now extremely widespread. It is a problem in every county in Utah, is considered con-sidered a serious problem in 24 counties, and is the most serious seri-ous weed present in many of the counties. It occurs in cultivated cul-tivated fields and waste places, particularly thriving on somewhat some-what saline soils. The greatest infestation in Beaver County is the Pine Creek area. With some found in Manderfield and several patches in and around Beaver. A few small patches are found in Minersville and South Milford. Control White Top has been and can be controlled by clean cultiva-t'on. cultiva-t'on. To be successful, this must be done thoroughly every two to Ihree weeks during the growing season and will- take two to three years. A more practical method consists of a combination of cropping and chemicals. For example, white top on crop land has been effectively ef-fectively controlled by the following fol-lowing procedure: Plow the j land early in the spring and j prepare a good seedbed. This sets the weed back. Apply about 40 lbs available nitrogen nitro-gen per acre and seed immediately immedi-ately to grain. The fertilizer will help the grain crop to t;row rapidly and provide competition com-petition to the weed. Spray with l'2 lbs 2, 4-D per acre when the prain is between the stooling and booting stage. After the crop is harvested, plow and cultivate or spray with 2, 4-D as fall growth appears. ap-pears. This program should be followed as long as is necessary, probably three or four years for complete control. White top can be controlled COUNTY AGENT TELLS METHOD OF CONTROLLING WHITE-TOP WEED (This is another in a series of articles on noxious weeds j written especially for The j News by County Agent Grant Esplin. Other articles will appear in future issues). Description White top is a perennial noxious weed. It reproduces from seeds and extensive coarse underground rhizomes or root-stocks. root-stocks. As the name implies, it has white flcwers and a patch in bloom gives a snowy-white appearance. This weed produces pro-duces reddish - brown seeds which resemble radish seeds and are about the same size as alfalfa seeds, making it difficult diffi-cult to clean from alfalfa or in waste places such as ditch banks, fence lines, roadways, railroad right of ways, etc., by spraying with 2, 4-D twice each year for a number of years I This should be done in the spring and then in the fall if re-growth appears. Small patches in waste land I or even in crop land can probably prob-ably best be controlled by the use of a soil sterilant such as atlacide or a chlorate. Six to eight lbs per square rod mixed with water and sprayed on or broadcast dry is the recommendation. recommen-dation. This kills all vegetation vegeta-tion and nothing will grow here for a few years. Remember, good farming methods are the best tools in effective weed control. |
