As will be noticed in the engraving, the THS LOOSE SMUT 101 relative growth of the three plants is practically thesame as it was after the seeds were three days in thegerminator. In Kansas Professor Kellerman made a special seriesof experiments, which showed that there was an increase. FIG. 80. OATS PLANTS TWO WEEKS OLD. ONE-HALF NATUKAL SIZE. of from four to eio-ht bushels per acre over that ac-counted for by the mere prevention of the smut, whenthe seed was treated with hot water. Professor Arthur has shown that the oats may betreated with hot water long before the time of planting,with as good results, both as to prevention of smut andincrease in yield, as when treated just before planting. 192 FCifG] AKD FUXGICIDES • Tlie following method of treatment with hot waterhas been recommended, as adapted to the facilities ofmost farmers.
