CHENNAI: Corporation will procure more fogging and spraying machines for control of mosquitoes next week, said Mayor M. Subramanian on Friday. Each ward would have machines of its own, he told a gathering of members of Exnora International at a function. The Corporation would get an additional 115 fogging and 200 spraying machines to cover all areas in the Corporation limits, he said. The meeting had been organised to distribute fogging and spraying machines to five Corporation Zones. While the Corporation has given it five machines, Exnora has bought one from its own funds.
