of summer spores. However, the danger from heavy applications of 

 liquid lime-sulfur during the summer should not be overlooked. 



Sprays for the Second Brood of Codling Moth 



In most Hudson Valley orchards treatments for the second brood of 

 codling moth have not been necessary in past years. In a few orchards, 

 where codling moth has become a problem, protection from the second 

 brood may be necessary in some years. For this, one or two appHca- 

 tions of a fixed-nicotine compound may be used in August. Three 

 quarts of summer oil plus % pint of nicotine may be used instead of 

 the fixed nicotine.

4. Selecting Machinery and Equipment for Making Appli- 

 cations. After the grower has studied carefully his insect and 

 disease problems and has worked out his spraying program, he 

 must then determine the machinery and equipment he will use 

 in carrying the program into effect. It must be adequate for 

 the purpose, and it should not represent an investment of 

 money beyond the point necessary to accomplish the purpose. 



Many kinds and types of machinery and equipment are 

 available. In considering them the grower should take into
