in the off year, may provide from last year's crop enough flies to infest the whole 

 orchard. And the flies emerging from beneath such a tree will soon seek out a 

 bearing tree, Vfe should destroy them where they emerge and not wait until they 

 have reached their destination and are concerned, not with feeding, but with layinp 

 eggs, 



Apple maggot flies are sluggish. They fly from place to place by short hops. 

 Spraying or dusting the whole orchard as well as the bordering trees and shrubs 

 will prove effective. And let's not neglect those scattered apple trees within 

 infesting distance (about 200 yards). If controlled 100^, and that is a practical 

 goal, we not only simplify grading and marketing but simplify our job next year. 

 No insect renders an apple less usable than apple maggot and none is less influenced 

 by the spring and early summer program. It appears in late summer and must be 

 combatted after it appears. July is the critical month. Let's make the most of it. 



POiiOLOGICAL PRARAGRAPHS 



Ap£le Storage Air Purifier Plans for a home-made device which will purify 

 ! ^Y^^^ ^ storage v/ill soon be avai]a ble from the University. These plans are 

 intended for storages of two sizes, the smaller, around 1^00 bushels, and the 

 larger 10- 15,000 bushels. One of the advantages of this type of equipment is its 

 cost, >7hich will be considerably less than the manufactured Air Purifier. Ttffo of 

 these pieces of home-made equipment are now in successful use in Massachusetts , 

 Interested growers may contact F. 1?. Southwick of the Pomology Department. The 

 new plans should be available before the next storage season. 



£i§^ Archives The Ilassachusetts Fruit Grovfers Association was organized in 

 W9h and the Worcester County Horticultural Society was the sponsoring organization. 

 A committee has been appointed, with George Ilingin as chairman, to be knovm as the 

 Archives Committee for the purpose of assembling all sorts of documents, mementos, 

 and records having to do with the history and development,- of the fruit industry 

 l^JJ:a^ '^^^'^^^' i" ^hich the mOk has had an important part. Readers of FRUIT 

 NOTES are asked to check their files and forgotten storage places to see what con- 

 tributions can be made to the archives of the IIFGA. Ytoatever you find, however 

 trivial or unimportant it may seem to be, should be made available to the Committee. 



Poison lyy Ilid-sumraer is the time to eradicate poison ivy. Spraying with 

 a material such as ammonium sulfama.te when the plant is in full leaf is effective. 

 A new publication, Special Circular No. 190, by J. S. Bailey, tells how to proceed 

 with the various materials and what may be expected from them. It also tells how 

 to treat for ivy poisoning. Poison ivy is altogether too common in fruit plantings. 

 One grower has difficulty getting apple pickers because so many of his trees are 

 embellished by this plant. July is a good time to embark on an eradication campaign.
