Show ORCHARD TREE PEST KILLED an Jnae Scale Cnntralled by Nat. urn I tn.my In Korm of Ulaeaae of Funaua Growth Checks Ita Spread. (Mr C. K. RANIIOHN, Kntomoln,l.t. Ok-lahnma Ok-lahnma Agricultural KxpTiment Hla lion I During the last two or. three yeara thla departiuont baa been experimenting experiment-ing with a natural enemy of tho Bun Inw tjrulo. Thla enemy la a disease In the nature of a fungoua growth. In oiithern lutltudea It haa been used even to a commercial extent for controlling con-trolling the acnle, but on account of the Weathor condition! of thla atnte It hua been aupposi-d that such a disease would either full to propagate Itself dining the summer or be entirely too dellcute tp withstand the low winter temperature. Careful experimentation, however, baa proved the disease Is very hardy and cnpable of propagation to a very beneficial extent In our Infested In-fested orchard. . Oftentlmen disease of a serious nature na-ture are Introduced and scattered by Insecta und other Ufceni-lea In general. This disease, however, la not capable or doing any damage to anything except ex-cept the Ban Jose Scale and allied forma. It use In oreharda, groves, "und public parka, aa ahown by our experiment!, ex-periment!, will be of a very great advantage ad-vantage In checking the local spread of the 8nn Jose Scale. It la of the anino nature the lliach bug dlseaae but Ita appearance on Infected Inaeeta Is not nearly aa Biaptruoua aa the latter. To an or-4inry or-4inry observer It appeara to be no tnfo than tho mold which Is commonly common-ly (resent on damp hrend a few d.iya' M.
