Show The Effects Of Spraying Demonstrated On An Orchard In This Valley by an Expert. Mr. C. A. Illckenlooper, Secretary of the State Hoard of Horticulture has Just returned from Cache Valley wlieic lie lias been Investigating the lesttlts of experiments conducted by K. I). Hall of the Utah Experiment Station, on the ellects of spraying and banding for the codling moth in apples. It Is a well known fact that this pest for years has been one of the greatest draw back to the apple Industry. Indus-try. In fact It lias totally dlscourag-ed dlscourag-ed a great many of the fruit raisers In this state. The methods followed by Mr. Hall are as follows: Through spraying with Paris Green as recommended in bulletin 10 of this Hoard, of which Prof. Hall Is an advisory member.. In connection with the spraying be lias also bandaged the tree with a strip of burlap to catch what larva might have escaped the poison. The beauty of Prof. Hall's work is that It Is not merely theory but he has demonstrated demonstrat-ed It on a commercial scale. In the orchard of Thos. Smart of Logan, where a great part of this work has been done there arc over four hundred hun-dred trees and Mr. Smart says that previous to Prof. Hall's taking Ills orchard for experimental purposes In the spring or 1H01 it was the exception to have any apples free from worms. A careful estimate lias been made of the fruit on the trees and not less than oil per cent arc free from worms. Mr. Illckenlooper spent over an hour in the orchard and failed to llnd a single wormy apple. This fact demonstrates dem-onstrates the thoroughness of Prof. Hall's llrst spraying. The surprising feature of this experiment was the fact that some trees which were bidder bid-der by a thicket on one edge of the orchard were overlooked In the spraying spray-ing and on these trees every apple bad fallen otT through the excess of worms and these had as much fruit on as the others In the beginning. The same was true of an orchard in the immediate vicinity that had not been sprayed. In this orchard Mr. Hichenlooper found the fruit nearly all on the ground and what little was was left on the trees was badly Infest ed with codling moth. Mr. Hall's tesults arc corroborated by the practical In this part of the state. Mr. Wm. (llbbs has a small orchard of :t." Hen Davis trees that be thoroughly sprayed once as soon as the petals of bloom bad fallen, at a cost of $l.7,"i, and lie secured from that one sprtijlng about hs per cent of apples ap-ples that are now on the trees free from worms and are loaded at the present writing. Also I). M. Campbell, Camp-bell, who lias a large tipple orchard on Providence licnch, lias sprayed his trees three times and bandaged them during tho summer and it Is estimated estimat-ed that be has US per cent of Hen Davis free from worms and from U.'l per cent to Ho per cent of these varieties varie-ties free from worms whllo his neighbor neigh-bor who did not properly spray has all the way from one to sixteen worms In most of his apples. In fact wo found very few In tlicorchard that was free from worms. Hortlcultuial Hulletin. |
