Show WHITE TOP. White top is a perannial weed -which produces from seeds and under ground roots. It reproduces the same way as morning glory and Canadian thistle. It is carried to new fields by water, animals, wind, etc. In cultivation, if a root is broken off and carried to another part of the field it may grow and be the means of starting a new patch of the weed. We have now but few patches of white top in Iron county, and those i who own land where it has a start should adopt methods of controll- j ing it immediately. One method oscd is intensive cultivation in which the leaves arc not allowed to reach the i surface of the ground; another ? which is becoming more prevalent is ) spraying with sodium arsenate two t or three times during the summer when the plants are young. |
