Boron should be applied to orchard soils every three years. Borax is the 

 most common material used. The rates of application per tree vary with age and 

 size. Apply one-quarter pound of borax to young trees, one-half to three-quarters 

 pound to medium age and size trees, and three-quarters to one pound to large or 

 mature trees. Boron may be applied as a foliar spray on a trial basis. 

 Polybor-2 or Boro Spray applied at one-half pound per 100 gallons of spray one 

 and three weeks after petal fall have given satisfactory results in New York 

 State. 



The amounts of fertilizer applied to trees which have received annual appli- 

 cations of 200 pounds or more of hay mulch per tree may be materially reduced or 

 entirely eliminated. Tree performance should serve as a guide in determining the 

 extent to which the rates of fertilizer may be reduced. 



In young, non-bearing orchards, it may be possible to produce sufficient 

 high quality mulching material for the young trees by broadcasting 500 to 800 

 pounds of mixed fertilizer per acre. Place the mulch in a band under the spread 

 of the branches. The amount of fertilizer required for the trees with this 

 system of culture will vary with the quantity and quality of mulch applied around 

 each tree. If the trees are not making sufficient growth, one-eighth pound of 

 ammonium nitrate per year of tree age may be applied to the mulch. 



Recommendations for fertilizing peach orchards are given in the following 

 table. The amounts given may need to be increased if the trees are in a heavy 

 sod. A suggested increase would be to double the amount of nitrogen.

Extension Entomology Program Areas of Responsibility within the 



College of Agriculture Staff. 



No single individual now has entire responsibility for the Extension 

 program concerned with insects and their control and related subjects. Instead, 

 several persons are listed officially as part-time extension and have accepted 

 responsibilities for specific or general areas. Others, although not officially 

 assigned to extension responsibilities, do assist in certain parts of the program. 

 The following outline is provided for your convenience.
