bacterial organism that is probably 

 identical wifli that of crown gall as 

 found on other trees. The disease in 

 most cases does not seriously affect the 

 tree, although hardly a quince tree in 

 California is free from it. 



Grapes are often diseased, the gall 

 being found on cuttings at the cut end 

 or in grafted vines at the place where 

 scion and stock unite. The European 

 varieties are more susceptible than the 

 American species. It has been demon- 

 strated that varieties of grape resistant 

 to the phylloxera are also resistant to 

 crown gall, and these varieties or other 

 varieties grafted on this stock are in all 

 ways to be preferred. 



For the control of crown gall disease 

 the following is suggested: Grow the 

 seedling in soil that is supposed to be 

 free from the disease germs. Grow, if 

 possible, stock having some natural re- 

 sistance to the disease. Gertain kinds 

 of plums, as the German and Italian 

 prune (Fellenberg), appear to have 

 strong resistance to crown gall. Grape 

 stock of the Rupestris St. George var- 

 iety, according to experiments of Dr. 

 George G. Hedgecock, show strong re- 

 sistance to crown gall as well as to 

 phylloxera. He also shows certain 

 varieties of apples, such as Northern 

 Spy, Ben Davis and Bellflower, to be 

 very resistant. A large number of 

 native species of plums are to be found 

 in the United States, many of which are 

 suitable for stock of the stone fruits. 

 Among these are several types of 

 hybrids that are vigorous and are used 

 in certain sections as stock. There are 

 Chinese and Siberian species that may 

 be excellent for stone fruits. In Cali- 

 fornia there are three or four wild 

 species of Prunus that may be adapted 

 for certain sections and certain fruits. 

 One of these is the California wild 

 plum, Prunus subcordata, var. Kelloggii 

 or Sisson plum, found growing near 

 Mount Shasta. Then there is the desert 

 apricot, P. eriogyna, growing on the 

 very edge of the desert. This is a bush, 

 rarely a tree, from six to twelve feet 

 high. The seedlings resemble the cul- 

 tivated apricot somewhat in appearance 

 of leaf. The pits germinate quickly, in 

 ten to fifteen days, and if sown early in 

 ■the spring they would not reciuire layer- 

 ing. In general appearance and size the 

 pits are quite similar to those of Myro- 

 balan. A strong growing tap root is 

 quickly developed. It is not known 

 whether this species will easily trans- 

 plant or how well it is adapted to the 

 stone fruits. It is closely related botan- 

 ically to the apricot. The desert almond, 

 P. fasciculata, is native over a consider- 

 able area of Southern California. It is 

 a small, slightly thorny shrub, about 

 four to six feet high. Pits small, irreg- 

 ular in shape, thin walled, smooth, with 

 sharp ridges. The Texas almond, P. 

 minutiflora, maximum growth about 

 twelve feet. It is found entirely in 

 Texas and is often badly infected with 

 crown gall. Then there is a Mexican 

 almond, P. microphylla, which closely 

 resembles the Texas almond. These 

 would doubtless be adapted to the 

 peach and almond, but might not show 



Even should 



you own a bif;, en^me- 



driven, power sprayer, there 



is an almo>>t constant need for a 



light, powerful, hand sprayer. I his 



Ar^lUICT Compressed 



'^^""*,r SPRAYER 



is the machine for small orchards and vineyards 

 and for places where a power machine can't 

 go. It handles perfectly any spray material. 



This sprayer throws a spiral, mist-like spray, driven 

 by an air pressure of up to 60 pounds. 



The heavily galvanized, riveted, iron tank holds 3}-i 

 gallons of spray and empties itself on one charge of air. 



The seamless brass air pump can be in or outside the 

 tank, as you prefer. A positive-acting valve keeps all 

 spray material ovit of the pump. 



The nozzle with its spiral plunger — a patented, exclu- 

 sive Acmefeatuie — is non-corroding and non-clogging. 



The plunger cleans the nozzle at every operation. 



Brass extension rod for tree spraying, and crooked 

 nozzle for low-lying vines, can be furnished if desired. 

 Heavy 3-foot hose and adjustable shoulder-strap are 

 part of the regular equipment.
