SPRAYING IN NJ2BRASKA. 



C. G. MAKSHALIi, LINCOLN. 



The aim in preparing this circular is to place in the hands 

 of farmers and others who are growing fruit for the home 

 supply a simple guide to follow in fighting the more trouble- 

 some of the insects and fungus diseases that infest our Ne- 

 braska orchards. 



It is not necessary at this time to go into detail as to the 

 life histories of these pests, or to take up and discuss at 

 length the advantage of fighting them. The fact that our 

 orchards are infested with these pests confronts us and the 

 question is how to successfully combat them with the least 

 trouble and expense. We are not so much concerned about 

 how they came into the country and how they are perpetu- 

 ated as we are about how and when they work and the sprays 

 to use in fighting them successfully. A few suggestions, 

 however, as to the objects of spraying and the results to be 

 obtained may not be amiss. 



The necessity of making this phase of the orchard work a 

 part of the plan in carrying out the details connected with 

 growing of good fruit has been emphasized by the many eX' 

 periment station publications and by the agricultural press 

 in general. It is recognized by the up-to-date fruit grower 

 and farmer as a feature of the work connected with success- 

 ful fruit culture that is just as important as cultivation and 

 pruning. In fact, the commercial apple grower in many sec- 

 tions would rather dispense with, for a single season, either 

 cultivation or pruning or both than with spraying. 



It has been proven beyond a question that apples may be 

 kept almost absolutely free of insects and fungus diseases 

 by proper spraying when fruit on adjoining rows not sprayed 

 "will be practically worthless as a result of the presence of 

 worms and scab. The fruit on properly sprayed trees last 

 season was from 90 to 9S per cent free of worms, while on un- 

 «iprayed trees the percentage of wormy fruit was almost as
