India weighs restricting Carbosulfan insecticide after Paraquat ban proposal
Farmers in India use a bug-killing chemical called Carbosulfan to protect crops like rice, cotton, and vegetables.
The Indian government is now thinking about limiting how the chemical can be used.
A decision is expected by the end of August.
This happens just after the government proposed banning another farm chemical, Paraquat, because it is very poisonous to people and animals.
Carbosulfan is sold in India by a company called FMC India under the brand name Marshal.
The company says the insecticide works well against many different pests.
Government experts call Carbosulfan 'highly toxic' and have recommended restrictions.
Food safety is a big reason for the worry: Europe allows only a very tiny amount of the chemical on imported food, and India's own food regulator has set different safe limits for rice, chilli, and dried chilli.
These checks are meant to keep the food we eat safe while farmers still protect their crops.
The government's final decision will affect what farmers can use in the future.
India is considering restricting Carbosulfan, an insecticide used on paddy, cotton, and horticulture crops, with a final decision expected by the end of this month.
The move follows the government's July 14 draft order proposing a blanket ban on the herbicide Paraquat, citing severe toxicity to humans and animals.
The Agriculture Ministry, which categorises Carbosulfan as 'highly toxic', acted on a recommendation from the Central Insecticides Board and Registration Committee (CIB&RC).
FMC India sells Carbosulfan under the 'Marshal' brand; FMC Corporation agreed in May to sell its India commercial business to Crystal Crop Protection for $252 million.
Experts say Carbosulfan is an issue for EU exports due to the EU's maximum residue level of 0.01 mg/kg, while FSSAI has set MRLs of 0.2 in rice, 2 in chilli and 20 in dried chilli.
