Show FIND CAUSE OF FLAX WILT experiments made by expert at north dakota college leads to belief disease attacks wheat prof bolley of the north dakota agricultural college has or a num ber of years been experimenting to determine the cause ot flax wilt and to find a remedy for it the result has been the production of flax seed resistant to disease far ther investigation has led him to believe that diseases similar to flax wilt attack wheat and may be controlled largely by the methods he suggests for the treatment of prof balleys Bol leys experiments lead to the conviction that the flax disease brings about immunity to its own at tack and that extremely resistant beed can be obtained by the careful selection of seed which each year matures on flax sick soil seed taken from a diseased crop and run in the usual way through the farm fan ning mill until all lightweight light weight seeds are blown out has been found by prof colleys experiments to be decidedly more resistant to wilt than the seed ordinarily sown the adoption of this procedure tor several sea sors on flax sick soil has developed such immunity to disease as to make it seem probable that a continuance of the process year after year will enable the farmer to secure lory yields this process however should not interfere with a proper rotation of crops especially when the tanner uses his own home grown seed re distant seed thus obtained from any of the standard corti sorti however will lose its power of resistance to dis ease upon failure to follow the plan outlined the importance of persis tence in such following year after year Is shown in the fact that in most cases resistant seed will develop some V eak plants each year which produce lightweight seeds and these must be dislodged each season by the fanning mill otherwise the power of resistance gained in the original effort will be lost the experience 0 the minnesota experiment station shows that homebred home bred seeds of all grains are more likely to produce better results than seeds brought irom a distance or from regions where climatic soil and conditions are dif terent |
