Conclus ions 



Drenching of Red Delicious with Benlate^ at commercially recommended 

 rates results in benomyl levels which are likely to be below that of 2.0 

 ppm. Care must be taken during drenching to ensure that adequate levels of 

 benomyl are appied for effective decay control. 



The application of Benlate^ as part of the waxing operation on the 

 packingline is more difficult to control and may result in benomyl levels 

 above 2 .0 ppm. 



Benomyl levels in treated apples are reduced by prolonged, regular or 

 "CA" storage, and also by washing. Precise residue levels can be determined 

 by having fruit tested by a qualified commercial laboratory.

HERBICIDE SELECTION FOR SMALL FRUITS 



Dominic A. Mar in i 



Regional Fruit and Vegetable Agent

When it comes to selecting herbicides to use on small fruit crops, a 

 number of factors have a bearing on the material to choose. Some of these 

 are the small fruit crop being grown, and in some cases, the variety, the 

 predominant weed species to be control led, whether they are annual or peren- 

 nial weeds, and whether the material is to be used for pre-emergence or 

 post-emergence control. Soil type has a bearing on the rate to be used and, 

 in certain cases, the degree of safety to the crop. 



The following outline lists the herbicides included in the I986 New 

 England Chemical Weed Control Guide for Small Fruit with a brief summary of 

 crop uses and weeds controlled. For complete information refer to the Guide 

 and to the label for each material. 



Chloroxuron (Tenoran") 



Uses: strawberries; pre- or early post-emergence. 



Weeds Controlled: most broadleaf weeds up to 2 inches, galinsoga up to 3/^ 



inch, weak on grasses; good in fall on chickweed and fall and winter weeds. 



DCPA (Dacthal"^) 



Uses: strawberries; pre-emergence, shallow, incorporate or 1 inch water 

 within 7 days. 



Weeds controlled: crabgrass, foxtail, chickweed, lambsquarters, purslane; 

 does not control galinsoga, ragweed, smartweed, or mustards.
