Bengal Cooperation Minister Arup Roy on Wednesday asked farmers to purchase pesticides and bio-pesticides only from registered pesticide dealers having valid license.
"Special precautions must be taken during transport, storage and handling. Spray equipment should be regularly cleaned and maintained to prevent leaks," Roy cautioned the farmers speaking at a function here.
The minister also observed that people who work with pesticides should receive proper training in their safe use.
The Bengal Chamber of Commerce & Industry (BCC&I) in association with Hindustan Insecticides Limited (HIL) and Mission for Integrated Development of Horticulture (MIDH) organised the programme to make awareness on Safe Uses of Pesticides.
