Locatin- Cause of Pressure Lo ss in P ower Spra yers 



YJhen a sprayer fails to maintain pressure, a systematic check of the 



outfit will usually discloce the cause of the trouble. Here are a few su£;- 



gestions: (1) Is there sufficient liquid in the tank to cover the intake? 



(2) Is the strainer on the end of the feed line clojjged? (3) Is the strainer 



in the sediment vrell clogged? (4) Are any valves held open by solid particles-- 



particularly intake valves? (5) Are any valves stuck? (6) riave the discs 



worn so that there is too great a discharge from tiie nozzles? (7) Is there 



an air leak in the feed line? (This may occur v;ith suction feed outfits.) 



(6) Are any of the plungers leaking? (9) Is the engine operating at the proper 



speed? (10) Is the pressure regulator out of adjustment? rv p n

N ew Grape s 



A recent issue of the American Fruit Grov.'er calls attention to the 

 Golden Lluscat and Concord Seedless as two new grapes of value. Both of these 

 introductions from the N. Y. (Geneva) Station have fruited in the State College 

 vineyard, but the results v.'ere disappointing. Golden I.iuscat is mucn too late 

 for our short grovvdng season. Concord Seedless is an interesting novelty but 

 hardly worth planting if one v/ants grapes larger than a half grown pea seed.

Strawberries Resistant to Red Stele 



Strav^berry growers who have had trouble with Red Stele will find a few 

 varieties which are resistant to that disease. According to Q. G. Boyd, Path- 

 finder, Beauty, Aberdeen and Ilev/ Jersey No. 312 (a new late seedling as yet 

 not named) will grow satisfactorily in the presence of Red Stele. No other 

 varieties are known to be resistant to this disease. Pathfi:ider has been one 

 of our heavier producers and is an attractive berry. Beauty has not done too 

 v/ell in the State College planting but should be tried v/here Red Stele is a 

 problem. N, J. No. 312 looks promising as a late variety but needs further 

 testing. ^,p_P,
