EXTENSION 



For extension get 3-8 inch or 1-2 inch gas pipe. Clean 

 out the nozzles in the spring before you begin using them. 



NOZZLE 



For mist spraying, we are making use of the disc type 

 of nozzle. If you want to use a large amount of spray, use 

 the disc with a large opening. 



There is the straight nozzle and the long tailed. You 

 will find that the long tailed nozzle is the best to use, as you 

 can get the spray just where you want it. The size is stand- 

 ard, and you can get reducers so you will not need to use an 

 extension unless you wish. 



INSECTICIDES AND FUNGICIDES 



For the San Jose scale use miscible oil and lime-sulfur 

 wash. The lime-sulfur wash is extremely difficult to handle. 

 Dr. Felt's formula has been giving as good resiilts as any 

 that I know of. For small trees not badly infested, use lime- 

 sulfur wash. Spray them with oil in the fall and then with 

 lime-sulfur M^ash in the spring. I believe much injury is done 

 in the winter. I think that the scale draws some sap from 

 the tree during the winter when there are thaws. 



CAEE IN THE TTSE OF LIME-SULFUR WASH 



It is advisable to use some protection over the eyes when 

 using the lime-sulfur. I would caution everyone, because we 

 are often careless in handling these materials. 



The gypsy moth is getting very near Worcester. Arsen- 

 ate of lead has not controlled the gypsy moth. I am com- 

 mencing to feel that the home-made Bordeaux mixture 

 is not good enough. 



DISCUSSION 



Quest. Why is the San Jose scale found on the blossom 

 end of the apple even if there is no scale on the tree? 



Mr. Frost. There probably is scale on the, tree though 

 it is not noticeable. After a dry season you can always look 

 for a great infestation of the San Jose scale. In a wet sea^ 

 son, considerable scale is washed off.
