3. Extension specialists recognize danger of poisoning and 

 recommend measures to minimize poisoning. Among these 

 might be (1) proper timing to avoid pesticide aoplications 

 to plants attractive to bees while in bloom, (2) applica- 

 tions in early morning or in evening when fewer bees will 

 come in direct contact with poison, and (3) avoidance of 

 contamination of area where spraying or dusting equipment 

 is being filled, particularly if there is standing water 

 in vi ci ni ty by bees . 



Suggestions to Improve Grower-Beekeeper Relations : 

 Have definite agreement as to: 



1. Number of colonies wanted. 



2. Strength of colonies. 



3. When colonies are to be moved in and out of orchard. Bee- 

 keeper needs 48-72 hours notice. 



4. Distribution of colonies in orchard. 



5. Avoidance of use of harmful pesticides while bees are in 

 orchard . 



6. Rental price with terms of payment.

ENVIRONMENTAL FACTORS TO CONSIDER WHEN SPRAY THINNING APPLES

Spray thinning recommendations for the concentration and timing 

 of application of such compounds as naphthal eneacetic acid (NAA), 

 naphthaleneacetamide (NAD) and Sevin have been established and used 

 quite successfully. However, these recommendations are based on 

 the assumption that weather conditions something near "normal" pre- 

 vailed prior to and during the period of spraying. As every fruit 

 grower knows, substantial variations from "normal" weather condi- 

 tions can occur during this time, and such variations may make it 

 necessary to alter the concentration of the material being applied. 



Environmental conditions may influence in two ways the amount 

 of a thinning agent that enters the plant and thereby affect the 

 thinning response. 



1. Weather conditions prior to spray application : Weather conditions 

 preceding the application of a thinning spray can influence the
