Show HMIONjDF SEED P0TAT0ESD1SC0NTIHUE0 Tho rapid spread of tho powdery stab diseaso ot tho potato in Malno pnd Now York and tho difllculty which has dovoloped In dotectlng by any practicable Inspection, tho presence pres-ence of Blight Infection by this diseaso dis-easo has led tho department, aftor an oxperienco of llvo or six months to discontinue further certification ot seed stock from tho Infected districts under quarantine. It is believed this seed certification under tho oxlstlng conditions, Instead of being a beno fit to Tho purchaser, may bocomo a BOttrco of positive danger, for tlio reason that tho purchaser Is given thereby a falso sonso ot security. Without such certification tho purch-aaor, purch-aaor, having been duly warnod, will mako his purchaso for planting filth a full understanding of tho risk. Tho only Federal certification of potatoes ns a condition of movement from tho infected districts is now ns tablo stock potatoes, and a strong effort Is being mado to phuo table stock potatoos on a more reliable basis bas-is to freedom from Infection. As all potatoes grown In Malno, both In dls trlctfl bolloved to bo uninfected as woll aB in tho known Infected districts, dis-tricts, aro under regulation as to in-torBtatn in-torBtatn movoment, Fodoral certlfl cation will bo continued for seed potatoes po-tatoes grown outsldo of the infected regions of that stato. Tho modification makes no chango in tho BtatUB of tho uninfected districts dis-tricts of Now York, which havo boon freo to ship seed potatoes without Fodoral Inspection. Tho public Is warned that all seed potatoes hitherto shipped from tho Infected districts may contain pow dory scab and that there must nee ossarlly bo some risk, accompanying their use, of tho introduction ot the' powdery scab diseaso. Undoubtedly thero ar0 forms, and In some Instances fairly constdorab.o areas within tho Infected districts In Maine and New York, which are still fico from infection, but it Is not posslblo to determine this fnct without with-out clooo scrutiny of every tuber, nnd such action Is Impracticable. In relation to tho southern market for Mnino seed potato stock, It is fair to Btato that this diseaso has not cs tabllshed Itself, and thor0 Is Borne evidence that it possibly could ' not establish Itself, In tho southern Atlantic At-lantic Coast and tho Uulf states, in theso states tho department experts aro inclined to bellovo that tho diseaso, dis-easo, if It appears at all, will bo limited to tho mountainous nnd cold or regions. |
