Orchard sprayers vrlth a pump capacity of 20 gallons or ;iicre per r.iaute have 

 rendered service above expectations in extinguishing fires in fann buildin~s. 

 Using 500 to 500 lbs, pressure, the veater is applied v;-ith an orchard gun creating 

 a fog in the room or enclosure \/here the fire brealcs out. This fog moistens all 

 enclosed surfaces as vcell as the air, and suffocates the fire by exo»luding the 

 oxygen. Control is obtained by the fog method \nth less v/ater, offers some 

 protection to the operator of the gun, and there is less water damage. Light, 

 mobile, motorized fire equipment operating on the fog principle, is being purcha^-e. 

 by rural communities. 



During mild weather the orchard sprayer can be kept in readiness or prepared 

 for fire service quickly. In freezing vreather the most desirable storage space 

 for the sprayer vrould be a frostproof room. Here water may be left in the sprayer 

 engine, p\.mp, and tanJc, so that the fog may be applied at the earliest moment 

 after the fire starts. 



Lacking a frostproof storage, the engine may be filled with anti-freeze. 

 The sprayer tanlc may be filled nearly full of vrater, leaving space at the top 

 for the expansion i/hicn occurs with freezing. The pump should be drained and 

 cone experienced worlonan assigned to replace drain plugs in case of fire. kal:e 

 3ure that water cannot seep in from the tanl: to the pump v/hile the machine is 

 stored. Check the battery occasionally to make certain it v/ill start the motor. 



Fire is a farm hazard of serious proportions, Vjliere co;iimunity fire equipm.?j.i. 

 is not available, insurance rates are high. The repair or r-'place-nent of a col,. 

 storage at harvest time due to fire is a problem no grox'/er v/ants to think abcnt. 

 A high pressure spray machine is the best type of fire fighting equipjiient .avail- 

 able for farm use, and needs only to be kept in readiness.

J^mi^nTROGEN FROj. THE SPRi lY TAIIK 



A rather revolutionary method of applying nitrogen to apple trees is current 1 

 receiving a lot of publicity. It consists of "putting urea, a nitrogen compound 

 v.hich contains 43/-0 nitrogen, in the spray tank and applying the nitrogen as a 

 spray. 



Five pounds of the uroa compound to 100 gallons is the recoriimended dosage. 

 The material may be put in with the regular in:;ecticidal and fungicickl sprays ^^r 

 5).pplied as a separate spray. There is no evidence that it is not compatible 

 ViJth regular spray materials and it has not causod any injury to foliage. Two 

 "'jhcduioE for applying arc suggested. The first consists of four sprays comnim- 

 ''-ng with tv;o pre-blossom or pink sprays, one cal^oc and one at first cover. Tjh 

 ■.^.'■■utir] r.ohfsdule of three sprays starts \Tith the calyx followed by first and 

 ^•■■i'ioj-.ri covor sprays. Trees which are low in nitrogen and have a tendency to .-cr 

 & -ij?;ht crop shouJd obviou"^^ly receive the first schedule. Trees v/hich have a 

 good ros'irve of nitrogen and sot hea-/;/- crops may get along all right with the
