Important 

 Information 



riecidiKnis fruit growers do not 

 need anything larger than a two- 

 gallon heater with the proper burn- 

 ing time. A larger heater produces 

 no more heat. We introdured the 

 first ort-liard heate in Oregon and 

 Washington and we have always 

 advocated a large number fit small 

 fires to the acre to give good pro- 

 tectimi, 



Burning Time: 



111 Hours. 



In 1910 and 1911 we sold 

 3.50,000 Bolton Orchard Heat- 

 ers in Oregon and Washing- 

 ton and every grower saved 

 his crop.

Spraying and Pruning to Combat Powdery Mildew 



[OfTice of Information, United Stales IJopartment of ABviciilliire.] 



AS ii rosiill of t'xpcrimcnt.s in tho llii- Pajaro Valley," oullines three dis- 

 I'ajaro Valley of California the 

 I'nited .Stales Department of Agricul- 

 tme is reconiinending certain spraying 

 and primini,' Ireatrnents to eonibat Ihe 

 powderx mildew, an apple disease that 

 serionsly menaces the apple induslrv 

 west of the Rocky Mountains. The 

 l)owdery mildew occurs occasionall.N 

 at least in nearly all parts of the 

 I'nited Stales. It is only in the West, 

 however, that it has done any consid- 

 erable (laniaKc particniarly in the 

 I'ajaro Valley, where the annual out- 

 put of apples is about 3,.')(l() carloads of 

 packed fruil. 



A new bulletin entilled, "Apple 

 I'owdery Mildew and Its Control in 



out 



linct phases of control method as fol- 

 lows: (1) Folia.i,'e spraying with iron- 

 sulphid mixture, precipitated sulphur, 

 or sidphur in some other very linely 

 divide<l form. (2) Winter pruning of 

 trees — (a) for Ihe i)ur|)iise of obtaining 

 the general slimulaling ell'ecis tliat 

 come from pruning at that time, and 

 (b) directed particularly toward the 

 eradication of mildew Iwigs. (.'?) Win- 

 ter spra.\ing with some spray that has 

 the elfecl of inducing a vigorous foliage 

 growth in the s])ring. 



The practice of careful and thorough 

 sunmier spraying year after .\ear will 

 gradually bring about a imich-improved 

 condition of the trees, but for the best 



results the entire method, as outlined 

 above, must be followed. This advice 

 as it stands is intended only for the 

 Pajaro Valley section, but tlie recom- 

 mendations, it is believed, may be 

 varied slightly to suit the requirements 

 of other apple-growing districts in 

 which the disease has become sufli- 

 ciently prevalent to recpiire attention. 

 In some sections, for instance, summer 

 spraying alone may pi-ovide a satisfac- 

 tory control of the disease. In using 

 sulphur great care must be exercised 

 to prevent such an over-application as 

 to burn the fruit. The bulletin is very 

 explicit in its directions as to the use 

 of sulphur. Growers in the Pajaro Val- 

 lc\- and other districts alfected by the 

 mildew should obtain the publication 

 before using the methods outlined 

 above. 



It seems probable that a cool, foggy 

 climate makes apple foliage more sus- 

 ceptible to powdery mildew. The fog 

 moisture also tends to dissolve such 

 sprays as may be used, so that spray 

 materials must be more carefully ap- 

 idied. Where the foliage is freepiently 

 subjected to washing rains the in- 

 jurious substances from the spray ma- 

 terials are washed ot!', but in the 

 Pajaro Valley the fog dissolves the sub- 

 stances and the leaves absorb the de- 

 structive elements which injure the 

 foliage. This has been especially no- 

 ticeable in the case of arsenic and paris
