In conclusion, the visual monitoring- trap for ABLM has been used 

 successfully to determine the need for an insecticide application before bloom in 

 many orchards. A new position for this trap may improve its usefulness by 

 allowing an earlier treatment decision and reducing confusion in the 

 identification of the insects captured. Dimilin holds promise as a new selective 

 treatment option for ABLM without threatening biological control of mites and 

 aphids. 



The ABLM has become an important pest in our region by having 

 developed resistance to organophosphate (OP) insecticides commonly used in 

 commercial orchards. Beneficial parasites which control ABLM very effectively 

 in unsprayed trees are killed by these OP's and other insecticides. Whatever 

 we can do to reduce insecticide use in our orchards, through the use of IPM 

 sampling techniques lor example, will help to spare these beneficials and allow 

 them to assist us in controlling ABLM.

POMOLOGICAL PARAGRAPH 



State of Maine Suspends Action 

 on Mandatory Tolerances for Alar 



International Apple Institute 



Robert Deis, Director, Maine Bureau of Public Service, in an October 10, 

 1986, memorandum to food processors said that because "many food processors 

 have voluntarily decided to discontinue their use of Damino/-ide-treated raw 

 products and many farmers, part iculirly apple growers, have substantially 

 reduced their applications of Daminozide--we expect this will lead to a 

 significant reduction in public exposure--we are therefore suspending 

 implementation of mandatory state tolerances in hopes that the-y will be 

 unnecessary. " 



The residue guidelines considered in Maine (and the basis for acceptable 

 voluntary action) are 1 ppm for infant and baby food and 5 ppm for general- 

 use, heated, processed food packaged before 10-1-86 and non-detectable and 1 

 ppm, respectively, thereafter. 



Rather than setting mandatory tolerances, it was pointed out the state was 

 taking non-regulatory steps which include a survey of processors to clarify the 

 extent and nature of their Daminozide policies and to monitor residues of 

 Daminozide/UDMH in products sold in Maine. The memoriindum to processors 

 indicated that if product is found to have residues above what the state 

 considers acceptable levels, voluntary withdrawal of lots will be requested.
