pest and that it is harmless to peach foliage, bark, and fruit, and can be 

 combined safely with sulfur and other fungicides. 



The preferred forms of DDT for this purpose are wettable powder or 

 dust. The wettable powder should be added to provide one (1) pound of actual 

 DDT in each 100 gallons of spray. If the powder contains 50% DDT, use two (2) 

 pounds in 100 gallons. A 40% powder requires two and one-half (2^) pounds; 

 and a 25% powder needs four (4) pounds. Vfettable sulfur may be added as 

 needed for brovm rot control. Where dusting is desirable a 5% DDT-sulfur 

 dust or a 5% DDT-sulfur-talc dust is suggested. 



At present, treatments are concentrated against the second generation 

 and applications are suggested at 10-day intervals beginning about July 15. 

 Until further information on residue tolerano is available, peaches should 

 not be treated with DDT less than 3 weeks before harvest. Therefore, many 

 of the common varieties of peaches can safely receive only one or two appli- 

 cations. Varieties ripening in September are subject to the greatest injury 

 by the third generation worms and this application of DDT appears safe and 

 practical on them. 



DDT kills the moths and the worms of the Oriental fruit moth by con- 

 tact with the spray or dust residue. Careful and regular applications should 

 not only give good control of the worms but it should reduce the moth popula- 

 tion to a minimum,

GOOD CROP STILL IN PROSPECT DESPITE FROSTS (National Apple Institute Bulletin,. 



April 26, 1946) 



Having passed the half^vay point in the period of freeze danger, the 

 prospects for a large apple crop have been reduced only in a few areas. Tele- 

 graphic reports for this bulletin indicate that lYestern New York, the central 

 part of the Appalachian belt, and parts of Ohio and Indisma have had serious 

 but localized damage, while other areas have escaped severe losses, 



NeV'T England ; Total prospects affected about 5 percent by damage to 

 Gravensteins, Greenings, Baldwins* Mcintosh still promise big crop. New York: 

 Average of five Hudson Valley fruit counties 35 to 40 percent of bloom gone, 

 but enough left for good crop if weather is favorable through bloom. In Vf'est- 

 em New York, enough buds are left for a moderate crop; damage is spotty 

 depending on altitude, varying from zero to over ninety percent. Mcintosh 

 and Cortland badly hurt; Spies and Romes probably suffered least. Orchards 

 neglected last year did not set buds for this year. Appalachian Area: Bud 

 kill heavy in central part of belt except on high ground . Yorks v/ere hurt 

 least, Delicious most. Blossoming generally one of heaviest on record. A 

 few orchards neglected last year defoliated early resulting in sparse bloom. 

 Total prospects for four states still good. Nev^ Jersey and Delaware: Some 

 damage mainly confined to low areas. Ohio ; Damage spotty on low sites re- 

 ducing Delicious, Stayman, Baldwin, Duchess. Romes generally okay. Prospect 

 for state continues average or better, Michigan ; No frost damage to apples. 

 Indiana ; Vincennes and south okay. Central and south central badly hit; 

 Delicious all killed in some orchards. Three-fourths of full crop possible 

 for state. Illinois and Missouri; Main producing sections unhurt, Wisconsin:
