only, or all of these applications are 

 necessary. If the mildew is bad addi- 

 tional sprayings may be necessary for 

 this disease alone, and in this case it 

 may be advisable to employ one of the 

 sulphur sprays recommended below. If 

 powdery mildew is the only disease for 

 which prpotectinn is sought one of the 

 following fungicides may be used: 



1. Atomic sulphur or some other 

 finely divided form of sulphur. Atomic 

 sulphur may be used at the rate of 2-6 

 pounds to each fifty gallons of water. 

 It seems probable that the minimum 

 strength recommended will give as

effective protection as the more con- 

 centrated solutions. 



2. The iron-sulphide mixture. (See 

 U. S. Department of Agriculture Bulle- 

 tin 120, 15-16, for original method of 

 preparation.) The rather laborious 

 method described in the reference given 

 does not seem to be necessary, at least 

 for the drier sections of Washington. 

 The modified Ballard formula is as 

 follows: Iron sulphate (copperas), 4 

 pounds; lime-sulphur, 3.3 deg. Beaume, 

 1 gallon; water, 200 gallons. A stock 

 solution of the iron sulphate should be 

 made and one pound to the gallon in a

convenient strength. Fill the sprayer 

 tank, start the agitator, add the lime- 

 sulphur and slowly add the requisite 

 amount of iron sulphate solution. In 

 order to insure complete precipitation 

 of the iron sulphide a slight excess of 

 lime-sulphur may be used. The neces- 

 sary insecticides like Blackleaf 40 or 

 lead arsenate may be added to either 

 the atomic sulphur or the iron sulphide 

 mixture. — Bulletin 1.54, Experiment Sta-

What will it do for me? 



Yuba 20-35 



It will plow 15 to 20 acres per shift. 



It will disc 35 to 40 acres. 



It will haul 20 tons on high speed on 

 a reasonably good road. 



It will operate a 32-inch separator. 



It will pull an independently operated 

 combined hirvester with a 20-ft. 

 cut. 



It is powerful enough for any job — 

 small enough to go almost anywhere — 

 simple enough for any one to drive. 



It is the ideal machine for the wheat 

 farmer, the rice grower, the bean 

 raiser and the contractor.

What will it do for me? 



Yuba 12-20 



It plows 10 acres, cultivates 25 acres, 

 and hauls 1 2 tons per shift. 



It will operate a 6-inch pump. 



It is narrow enough to go in 7-ft. hop 

 rows, or 7-ft. vineyards. 



It is the right design for beet growers 

 who plant in 20-inch rows. 



It is the only tractor for the asparagus 

 grower. 



The Model 12-20 and the Yuba plow 

 form a one-man outfit — even in the 

 orchard. 



An all around machine — though it was 

 designed especially for the orchard.
