APPLICATIONS 



It will often be necessary to 'i|>|)ly n siiifile .spray a number of times in order 

 to get all satisfactory results. Tliese iipplieations should be made at intervals of 

 from four to si.\ days until tiie insects disappear or greatly diminisli in numbers. 



One of the greatest successes of a spray is thorough application under high 

 pressure. With a common bucket or knapsack pump only the first can Ik; 

 accomplished, but if even this is observed good results may be obtained. If, 

 however, a power outfit can be had and a pressure of from one hundred to two 

 hundred pounds maintained, one spraying will usually suHiee with excellent 

 results. Young buds are not secure enough to bi- sprayed with :i power spraver, 

 and must be treated with a hand pump.
