Should I spray my plum tree?

Asked May 16, 2014, 9:40 AM EDT

I live in Reading, Pennsylvania, and have a semi-dwarf purple plum tree. In 2012, we had a lot of plums (a bushel), but when ripe, they tasted like they were rotten inside. I went to the ag center in Berks County and was told that the tree may have had brown rot. In 2013, I sprayed the tree but then had no fruit. This spring (2014), the tree had a lot of flowers. The flowers are gone, and it seems as though a lot of fruit is forming. Is there a spray or anything I can use at this time to help ensure that I get a good crop of plums?
