The district collector had collected samples of the seeds and sent them to a Nagpur-based laboratory. The laboratory informed Monday that the samples tested positive for HTBT cotton, an agriculture department official said.
The department has now asked officials of the Akot and Hiwarkhed police stations in the district to initiate action against the farmers, he said.
Shetkari Sanghatna conducted a `satyagraha’ on June 10 against the Union government-imposed ban on HTBT cotton by sowing the banned varieties.
The Shetkari Sanghatna, founded by late Sharad Joshi, is rooting for HTBT cotton saying that it can resist weeds, thus saving on herbicide costs.
“The government, both the centre and the state, have not conducted a proper study about the impact of HTBT cotton. Therefore the ban continues,” said a senior state government official.
