"We have requested government support for the state-wide bandh by suspending transport operations and have also reiterated our request for AIADMK's support," President of Coordination Committee of All Farmers Associations, P R Pandian told PTI.
The committee has given the call for the bandh protesting against Karnataka, the upper riparian state, and the Centre over the dam issue.
BJP has said though it was not in favour of a bandh, it would not oppose it as it was a decision of all farmers' associations.
The bandh call is also to press the Centre to stop the proposed construction of the dam and urge it to set up the Cauvery Management Board and Cauvery Water Regulatory Authority.
Also, the Cauvery Delta region should be declared a protected farm zone, the committe had said.
