or from a scanty coverage of the arsenical spray. A sprsy In- 

 tended for protection against curculio, but applied a v .= ek lete, 

 is about as efficient as a fire engine arriving after the fire 

 is out. 



Another example of t,.ii£ same thlr.g is found in iilclntosh 

 orchards vhere no Pink spriiy was applied this year. Leaves of a 

 particular size, siiov/ing that they were developed before bloom, 

 are ir> some cases literally plastered vlth scsb. But vhere the 

 trees vere given protection at that time, and since, iccb is con- 

 spicuous by its af;sence. 



Lime for Sprayinr Purposes 



It is becoming Increasin^rl;; evident t;;at "any old lime" 

 v.lll not do in the spray taiik. According, to 0. C. Boyd, tne right 

 ki^d of lime has real v -flue, the wron;, kind little or none. The 

 terj] chemic?! hydrated lime nas been used for years to designate 

 a lime vith tiie highest oossible "d.ount of calcium hydroxide and 

 the lowest oosslble amount of ordinary impurities like aia^nesium, 

 iron, aluminum, etc. Such a lime ii^ust of nece.isity be made from 

 a limestone high in calcium c -irbonate. Careful and complete slak- 

 ing of the burned lime is necessary in order to insure proper tex- 

 ture, fineness, and calcium ^//drojtide content. This product vill 

 contain not less than 70!^ calcium oxide in the form of calcium ny- 

 droxide. Pure calcium hiydro>:ide contains about 765' calciiun oxide, 

 -ience a chemical ^ydrated lime vill of necessity contain only a 

 very small amount o^ impurities and .^ maximum amount of t/ie de- 

 sirable ingredient, ctlcium hydroxide. 



v:hen a lime of high magnesium' content is placed in the 

 spray tank along with lime sulfur ana lead arsenate, the magnesium 

 hydroxide acts as an inert material. It apparently fails to re- 

 duce the chemical action bet"een lime sulfur and lead arsenate 

 and it also faili to reduce t-.e water soluble, arsenic and there y 

 fails to furnish protection to tiie foliage. '^:ie prircipal objec- 

 tion to magnesiiim in spray lime is th-^^t its presence automaticall 

 reduces the amount of the effective ingredient, c alcium iivaroxide, 

 and not as some have been l'=^d to believe, because of injurious 

 magnesium compounds formed. Incidentally, if tae ciiemical aydr:.ted 

 lime is not fresh, enough of the lime vill have cl-iant-ed to the 

 carbonate form to greatly' reduce its effectiveness in the spray 

 tank. 



Signs of S tarvat ion 



A fe^'^■ d^ys c- go J. K. Shav^ of tne State College vas asked 

 to look over an orchard v.hicn for some unaccorntable reason ,:ad 

 borne only a light crop last year and a :till smaller crop t.iis 

 year. The orchard had been fertilized rather liberally until aboit 

 19P9. Since then it ?ias been pruned but nas received little or no 

 fertilizer because the grover felt that ;,e nad been ^roving too 

 much wood, he doubted the wisdom of applying manure only to pro-
