BETTER FRUIT 



Page 15 



A writer in one of the leading agricultural 

 papers states: "It is poor policy to band trees 

 with sticky or greasy substances to prevent in- 

 sects going up. While it prevents the insects 

 climbing, it seems to be only a question of 

 time when the material kills the tree, especially 

 thin barked trees." 



This question was recently referred to Dr. E. 

 B. Fracker, state entomologist of Wisconsin, 

 who says: 



Banding trees with sticky substances has 

 long been recommended for the control of 

 climbing insects, such as cankerworms, tus- 

 sock moths, gipsy and borwn-tail moths, and 

 ants which may carry plant lice. 



Two forms of these bands are recommended 

 by park superintendents and tree surgeons as 

 being harmless to trees. One is Tree Tangle- 

 foot, made by the O. & W. Thum Company, 

 Grand Rapids, Michigan. The other is "Rau- 

 penleini" which the owner can mix for him- 

 self and which is used extensively in gipsy 

 moth control in Massachusetts and New Hamp- 

 shire. 



Too much confidence should not be placed 

 in banding as it is useful only for the insects 

 named, but for them it is a valuable control 

 measure. The writer has never heard of the 

 two substances described above injuring trees. 

 Perhaps the writer is referring to tar, printers' 

 ink, and some other compounds which are un- 

 questionably harmful. — Wisconsin Horticultur-

Export of Peaches Partly 

 Successful 



An experimental shipment of peaches 

 to Great Britain made during the 

 month of September shows that a de- 

 mand exists for this fruit if it can be 

 delivered in satisfactory condition. 



The quality of the greater portion of 

 the peaches was poor when placed on 

 British markets. The fruit held up for 

 a few days, then went down rapidly. 

 The deterioration was partly the re- 

 sult of overtight packing, which caused 

 bruising and led to the development of 

 decay, and partly the result of a lack 

 of ventilation in the packing and in the 

 ocean storage compartments. 



The peaches were packed in crates 

 holding ten double cardboard cartons. 

 The inside space was divided by corru- 

 gated cardboard into ten sections on the 

 plan of an egg box. The crates were 

 practically air tight. When placed in 

 cold storage the moisture from the fruit 

 was absorbed by the corrugated parti- 

 tions of the carton with the result that 

 the partitions became damp and lost 

 their shape. The cost of the crates 

 was approximately S3. 60 each, about 

 one-half the value of the peaches. If 

 shipments of peaches to Great Britain 

 are to be successful and profitable, a 

 cheaper crate with some provision for 

 ventilation must be used. 



Some crates holding 160 peaches sold 

 at private sale for £2 a crate (about $7 

 at the prevailing rates of exchange) or 

 about 3 pence (nearly 4 cents) each. 

 However, on account of the defective 

 condition of some of the fruit, claims 

 for reimbursement were made on one- 

 third of the sales. The United States 

 agricultural trade commissioner thinks 

 that better prices and a desirable pub- 

 licity would have been obtained at the 

 Convent Garden fruit auction. There 

 the peaches would have been sold in 

 competition with fruit from Belgium 

 and at least a better test of market 

 value would have been given.

 Life out 



requires powerful insecticides — 

 he is as tenacious of life 

 as a mud turtle 



BECAUSE the Codling Moth is a tough customer 

 and the principal insect enemy of Mr. Apple, 

 you can afford to take no chance. This little pest 

 breeds like the proverbial trouble- and if even one is 

 left, wormy apples and pears are the certain result. 



Eliminate every atom of risk by spraying with GRASSELLI 

 GRADE Arsenate of Lead just after the blossoms have fallen 

 (and at regular intervals later). That is certain death to them. 

 Don't risk your 1921 crop by using any ordinary insecticides 

 when you can be absolutely certain with GRASSELLI GRADE- 

 The Grasselli label protects your fruit income— it's your "fruit 

 insurance." 



GRASSELLI GRADE Insecticides and Fungicides have won 

 place as the World's Standard by their year-in-and-year-out, 

 unvarying uniformity and "triple A" strength. Behind the 

 Grasselli name is 82 years of Chemical leadership and the tradi- 

 tions of Grasselli Quality— no less. That is your protection. 



Specify GRASSELLI GRADE when ordering your spray mater- 

 ials from your dealer.
