Sri Lanka's paddy cultivation is threatened by destructive weeds which have already damaged nearly 20 percent of the harvest.
"Wild rice and weedy rice have spread in eight districts and if timely action is not taken could destroy the country's paddy cultivation," Bathalagoda Rice Research and Development Institute Senior Research Officer Anuruddhika Abeysekara told the Daily News.
Kurunegala, Batticaloa, Ampara, Vavuniya, Matara, Puttalam, Anuradhapura and Polonnaruwa districts' paddy fields have faced the threat. Due to this farmers are unable to take clean paddy harvest. Wild rice and weedy rice plants take much of the water, sun light and fertilizer, she added.
Farmers should be educated on ways to destroy the weed by experts such as agronomists, she said. First, farmers should identify wild rice and weedy rice in their paddy fields. They should let them grow for sometime before applying weedicides. Also using quality seed paddy is very important, she said.
