Terbacti 



Terbacil, the herbicide most recently labeled for use in or- 

 chards, may be used under non-bearing and bearing apple and peach 

 trees that have been established 3 or more years. Contrary to 

 other herbicides terbacil is less toxic to peach than apple trees. 

 Our experience with this herbicide is very limited but experience 

 both in Maine and Massachusetts indicates that its use should be 

 avoided on light soils with low organic matter content. 



Summary 



If used properly, herbicides are a useful tool in orchards. 

 Our 1969 recommendations for orchard weed control can be obtained 

 from your County Agent in early spring. Read the recommendations 

 carefully and prior to application read the label on the herbicide 

 container for further information.

EXTENSION STUDIES PLANNED FOR 1969 



Wi 1 1 iam J . Lord 

 Department of Plant and Soil Sciences 



Extension studies have served as a teaching method and have 

 provided suggestions and answers for increasing the efficiency of 

 fruit production. Frequently, they have been a cooperative effort 

 of two or more members of the Department of Plant and Soil Sciences 

 or conducted in cooperation with other departments of the College 

 of Agriculture. During 1969, extension studies will continue to 

 constitute an integral part of our Fruit Extension Program. To 

 keep growers informed of what studies are anticipated, they are 

 listed below with the names of the individuals responsible for 

 these activities. 



I. Evaluation of Waxing of Apples 



A. Purpose: Determine the response of Delicious and Mcin- 

 tosh apples to waxing before storage. 



B. Method: A study will be conducted during the 1968-69 

 storage season. Apples will be waxed in a commercial 

 packing line at harvest time, and effects on their post- 

 harvest life will be evaluated. Delicious will be eval- 

 uated directly after waxing and after post-waxing air 

 storage. Evaluation will include weight loss, appearance 

 change, watercore loss and internal breakdown development 

 Mcintosh will be evaluated directly after waxing and 

 after post-waxing air storage; the evaluations will in- 

 clude weight loss, appearance change and development of 

 brown core.
