Villagers of Gummadam, on the banks of river Krishna in Mahabubnagar district, yesterday noticed the blackbucks dead and informed the matter to forest officials.
"As per preliminary inquiry, we suspect that the blackbucks consumed pesticide and fertiliser used for maize crop. Some farmers had illegally grown the crop on the land belonging to revenue department, which is a submerged area of Srisailam reservoir," Mahabubnagar District Divisional Forest Officer (DFO) C Ganga Reddy said.
The maize crop has been destroyed, he said.
A case has been registered against two farmers, who had illegally taken up sowing of maize crop on the government land, under relevant sections of the Wildlife Act, the DFO added.
