Reevaluation of NAA as a Preharvest Drop Controlling 

 Chemical for Mcintosh 



Duane W. Greene 



Department of Plant & Soil Sciences, University of Massachusetts 



For the past 20 years Alar^^ has been the primary 

 chemical used to control preharvest drop of Mcintosh fruit. 

 The superior performance of Alar essentially eliminated 

 the use of those compounds available prior to its registra- 



tion. However, the registration of Alar is under review and 

 we still do not know what its future will be. More stringent 

 tolerance levels already have been set by the Massachusetts 

 Department of Public Health.
