FORMULAE AS NOTED ABOVE No 1 Paris Green Mix one pound of Paris green with an equal amount of flour add sufficient water to forma form-a thick paste stirring until all lumps are mixed dilute in 200 gallons of water add four pounds of lime slaked to a thin paste stir thoroughly and strain before using No 2 Bordeaux MixtureFInely pulverize pul-verize six pounds of copper sulphate and dissolve it in two gallons of hot water add to this fourteen gallons of water Slake four pounds of fresh lime into a thin paste stir until cool and then thoroughly mix the copper sulphate sul-phate solution with the lime to the mixture add water to made 40 gallons Strain the mixture carefully Double the above strength of this solution may be used without injury to the foliage and the mixture of copper and lime in the form of thin paste makes an effective ef-fective wash for the trunks of old trees No 3 Kerosene EmulsionDissolve onehalf pound of hard soap do not use resin soap in one gallon of hot water while still hot add two gallons of kerosene stir violently until the mixture takes on the appearance of whipped cream Dilute withjten times as much water Skimmed milk may be used as a substitute for the soap in making the emulsion using one gallon of hot milk to two gallons of kerosene stirring the same as when soap is used add water as above No 4 Resin Wash Resin 20 pounds crude caustic soda TS per cent five i pounds fish oil two and onehalf pints water to make 100 gallons Ordinary commercial resin is used and the caustic soda is that put up for j soap establishments in large 200 pound drums Smaller quantities may be obtained ob-tained at soap factories or the granulated j granu-lated caustic soda 98 per cent used I three and onehalf pounds of the latter being the equivalent of five pounds of I the former Place these substances with the oil in a kettle l with water to I cover them to a depth of three or four inches Boil for one or two hours making I mak-ing occasional additions of water orj until the compound resembles very black coffee Dilute to onethird the i final bulk with hot water or with cold water added slowly over the fire maki i I ing a stock mixture to be diluted to i the full amount as used When spray ing the mixture should be perfectly i fluid without sediment and should any i j appear in the stock mixture reheating I should he resorted to I As a winter wash for scale insects j and particularly for the more resistant re-sistant San Jose scale Aspidiotus per j I niciosus southern washes are necessary neces-sary In southern California for this I latter insect the equivalent of a dilution j dilu-tion onethird less or 66 23 gallons instead j in-stead of 100 has been giving very good satisfactin I NOTES AND SUGGESTIONS I In the preparation of the Bordeaux j I mixture care should be observed to use either an earthen or wooden vessel I The mixture will ruin a vessel of metal Satisfactory results in spraying depend de-pend upon the careful performance of the work Carelessness will result in dissatisfaction A good pump and i plenty of hose extension pipe and fine I nozzle are essentials The most experienced and successful I syrayers in Utah are unanimous in the I i opinion that the spraying should be continued I 1 con-tinued throughout the season or at I I least up to Aug 25 Cleanliness is the first step toward I I orchard disinfection All diseased trees I are sources of great production of I worms and fungus Sunlight is one of I I the best disinfectants j In order to catch all early insects it l is recommended that all fruit trees be I sprayed once with a combination of I Bordeaux mixture and Paris green before I be-fore blossoming and again with Paris green immediately after blossoms fall THOMAS JUDD President O H CHAMBERLAIN VicePresident J A WRIGHT Secretary Among the resolutions passed was the following I Resolved that the teachers in the public schools of Utah be requested to teach as far as consistent with their I position the elementary principles of plant growth leading as far as possible possi-ble to the propagation of trees vines and bushes including the processes of grafting and budding ofuseful fruits flowers and shrubs I This was followed by another Resolved that in the opinion of this board the general public is made acquainted ac-quainted with the best rules and formulas for-mulas for orchard disinfection through stations and consequently there is no occasion for orchardists to patronize vendors or proprietors of patented compounds com-pounds for exterminating insects It is urged that all who are interested inter-ested in progressive horticultural I methods should secure the bulletins I which are distributed free by the various vari-ous experiment stations and by the department de-partment of agriculture at Washington i Washing-ton LOCAL NURSERIES Onp of the most important matters the hoard has had under consideration has been to urge the fruit growers to select their stock from the local nurseries In line with this the following follow-ing resolution was passed Resolved that it is the unanimous opinion of the board that the best interests I inter-ests of the fruit growers of Utah demand de-mand that all nursery stock planted in this state be propagated and grown in Utah also that the individual members mem-bers of this board use their best endeavors en-deavors to persuade the farmers and orchardists of Utah to patronize only such nurseries as propagate exclusively all stock offered for sale excepting that all imported stock be labeled as such giving in each instance the location of nurseries propagating the same The board finished up its work about 5 oclock and adjourned subject to call I of the chair e e |
