other pests. Here they are listed from the earliest to the latest. Its up to 

 you to check costs and to choose the program best suited to your conditions and 

 operations. 



1. Dormant - DN - butyl phenol, 1 qt./lOO. A drenching spray required so 

 concentrations above 2x are often less effective. Fringe benefits: grain 

 and green aphid eggs killed; some reduction in San Jose and oyster shell 

 scales and red mite, better control of these and also bud moth if 2 

 quarts are used. 



2. Late Delayed Dormant - Oil (70" superior or regular 100" superior type), 

 2 gallons PLUS BHC (12% gamma), 2 Ibs./lOO. A drenching spray required 

 so concentrations above 2x are often less effective. May fail to give 

 complete control if egg hatching is delayed or temperatures are lower 

 than 65°F. You obtain all of the effects of the oil against mites and 

 scales plus these fringe benefits: grain and green aphids killed better 

 than with oil alone. 



3a. Up-to-Pink (in some fungicide application between Late Delayed Dormant 



and full Pink) - BHC (127. gamma) 2 Ibs./lOO. May not give complete control 

 if temperatures are lower than 65^. Fringe benefits: grain and green 

 aphids killed, some miscellaneous leaf eating caterpillars and sucking 

 bugs killed. 



OR 3b. Phosphates: TEPP, 1/4 (407,) to 1/2 (207,) pt; malathion, 2 lbs; parathion 

 (on non-McIntosh varieties), 1 1/2 lbs. Fringe benefits: grain and 

 green aphids killed; parathion excellent, malathion good against bud 

 moth, both good against miscellaneous caterpillars and sucking insects: 

 malathion kills active leafroller moths, parathion fair. Avoid slow 

 drying conditions, combinations with mercuries, and TEPP with glyodin. 



4. Pink (in a fungicide application) - Phosphates as in 3b just above. 

 Additional fringe benefits: earliest hatched red mites will be killed. 

 TEPP may be less effective here because of leaf curling. Avoid slow dry- 

 ing conditions combinations with mercuries, and TEPP with glyodin. 



In Case of Emergency 



Its already Petal-Fall and you realize its a bad "rosy aphid year". Some- 

 thing should be done on all except Mcintosh, Wealthy, and Duchess, even though 

 expensive 



1. Petal-Fall demeton, 1/2 pt. Avoid slow drying and combinations with 

 mercuries and glyodin. Other aphids and mites will be killed; of 

 little or no value against curculio. 



Newer Materials for Trial 



Follow manufacturer's directions in using Trithion between Dormant and 

 Delayed Dormant (not Late Delayed Dojrmant or later) . Promising as an aphid 

 control, other benefits doubtful at this writing. Cost may be too great. 

 Compatible with oil but compatibility with all fungicides not well known.
