SPRAYING DEMONSTRATIONS IN NEBRASKA APPLE 



ORCHARDS.* 



BY R. A. EMERSON. 



THE WORK OUTLINED. 



Purposes of the Demonstrations. — During the summer of 1906, spray- 

 ing demonstrations were conducted in six counties in southeastern Ne- 

 braska. The purposes of the work were to give a practical demonstration 

 of the value of spraying in the control of apple scab and codling-moth, 

 to determine the cost of spraying, and to learn whether it pays to spray 

 apple orchards under the conditions existing in this state. 



Cooperative Nature of the Work. — The demonstrations were carried 

 on in cooperation between the United States Department of Agriculture, 

 the Nebraska Agricultural Experiment Station, and six fruit growers of 

 southeastern Nebraska. The six orchards selected for the work are located 

 one in each of the counties of Johnson, Lancaster, Nemaha, Otoe, Pawnee, 

 and Richardson. The orchardists cooperating in the work were: 



John Gilligan, Falls City; manager, G. T. Grinstead. 

 Swan & Titus, Glen Rock; manager, J. G. Swan. 

 E. T. Hartley, Lincoln. 

 Morton Bros., Nebraska City. 

 J. E. Atkinson, Pawnee City. 

 Al. Russell, Tecumseh. 



The owners of the several orchards provided for the most part the 

 appliances, materials, and labor necessary for carrying on the work, and 

 did the spraying under the personal direction of representatives of the 



* The undersigned, as representing the U. S. Department of Agricul- 

 ture in the demonstration spraying herewith reported, desire it to be 

 understood by Nebraska fruit growers that the results obtained, while 

 showing a considerable gain in dollars and cents in favor of spraying, 

 are not as favorable, especially as regards the control of the codling moth, 

 as similar work elsewhere has shown may be expected. Various circum- 

 stances connected with the inauguration and carrying out of the work in 

 rather widely separated orchards combined to prevent as thorough atten- 

 tion to details as was desirable, and the present report is to be regarded 

 merely as one of progress. The orchardist may expect to save a con- 

 siderably larger per cent of fruit from codling moth injury than was saved 

 in the present work, and the amount of scabby fruit should be reduced 

 to practically nothing.
