What do they look like when they "don't develop?" Color? size? Dry or moist? and anything else you've seen.

Elsewhere you said they "look dried up."

Perhaps the problem is the dry berry mite.

Hi Jean, the berries start to develope normally, start to turn color,a few of the berries are perfectly normal, the rest partially develope and from half way down to the tip they are brown and hard. This description is probably as clear as mud :-).
By the way what is the treatment for dry berry mite? Any help you can give me will be very much appreciated.

Then scroll to page 9, and read the left column.

Jean, Thanks for the information, I've tried to stay away from sprays but in this case I'll see what we have available up here that will do the job. A lot of the pesticides have been taken off the market. Thanks again.
