In this work, we introduce dual Rickart (Baer) modules via the con-
cept of preradicals. It is shown that W is  -d Rickart if and only if
W =  (W)  L such that  (W) is a dual Rickart module. We prove
that a module W is  -d Baer if and only if W is  -d Rickart and W
satis es strongly summand sum property for d.s. submodules of W
contained in  (W). Via  (RR), we characterize right  -d Baer rings.
