Codling Moth (Apple Worm.) 



Spray with a stomach poison (No. 12) just before the blossoms 

 open. Repeat as soon as they fall. Repeat in two weeks. 



Oyster-Shell Scale. 



Spray trunk, branches and twigs thoroughly about June 5 in aver- 

 age seasons with No. 13a or 14, varying the date according to the 

 season. Repeat two weeks later. Old scales may remain all sum- 

 mer after successful treatment. 



Plum Curculio. 



Eats leaves in early spring and punctures small apples, causing 

 hard spots with woody places inside them. Spray with a stomach 

 poison (No. 13) just before the blossoms open. Beginning about 

 ten days after the blossoms fall, jar the trees about sunset and early 

 in the morning, spreading a white cloth beneath and killing the insects 

 which fall. 



Round=|-leaded Borer. 



Look for "sawdust " at the base of the trunk in October and from 

 this find and cut out the borers. Make a cone of wire mosquito 

 netting, fitting the trunk about two feet from the ground and setting 

 the other end in the ground, keeping the borers off. This will also 

 protect from mice in winter. 



San Jose Scale. 



Spray during the winter with lime-sulfur wash (No. 16) covering 

 every part of the tree thoroughly. If this treatment is impossible 

 for lack of facilities for making, or the number of trees to treat is 

 very small, use " Scalecide " i part, water 14 parts. In either case 

 use a nozzle giving a very fine, misty spray and apply very thor- 

 oughly. The lime-sulfur wash has given better results than " Scale- 

 cide " at this Station. Home-made " soluble oils " are still in an 

 experimental stage, in the opinion of the writer, and are not recom- 

 mended for thai reason. 



Woolly Aphis. 



White, woolly places on limbs in fall with lice beneath ; they may 

 also be present on the roots. Remove the soil to the top roots two
