Canadian exporters are slowing sales of peas and lentils to India, threatening C$1.1 billion ($762.95 million) in annual trade of the food staples, over risk that New Delhi may reject shipments under its tougher approach to pest control.fore more update www.ripplesadvisory.com

India requires shippers to fumigate crops with methyl bromide, an insect-killing gas, in the country of origin, but has historically made an exception for Canada, the world's biggest pulse exporter. Methyl bromide, an ozone-depleting substance, is not made in Canada, but is allowed for use in limited situations.

Canada's exemption, allowing crops to be fumigated on arrival in India, is set to expire on March 31, overlapping with the 30-40 days it takes for shipments to reach India from Canada. "It's just a completely dead market right now for us," said Tamara Khoma, trader at Providence Grain. The company rerouted a pea shipment to China that had been headed for India.
