Why in News?<\/h2>\n

The Indian Council of Agricultural Research (ICAR) has commercialized herbicide-tolerant (Ht) basmati rice varieties<\/span>, which they claim can control weeds in rice crops and support the water-saving technique of direct seeded rice (DSR).<\/p>\n

1. About:<\/strong> DSR is a modern rice cultivation method<\/span> where seeds are directly sown into the field<\/span>, bypassing the traditional transplanting of seedlings from a nursery.<\/p>\n

2. This method is recognized for its efficiency and sustainability<\/span>, benefiting farmers,<\/span> the environment, and the economy.<\/p>\n

3. Previous Context and Innovations in DSR<\/strong><\/p>\n

i)\u00a0 Historically, the Northwestern Plains, including Punjab and Haryana have used DSR<\/span> for growing Basmati rice.<\/p>\n

ii)\u00a0 The Green Revolution favored water-intensive transplanted rice leading to ecological challenges.<\/p>\n

iii)\u00a0 Innovations from 2014 to 2017 at IARI Karnal, such as TAR-VATTAR technology utilized climatic factors and effective herbicides like Pendimethalin to cut costs and conserve water.<\/p>\n

4.\u00a0 Development of Herbicide-Tolerant Basmati Rice<\/strong><\/p>\n

i) The Indian Council of Agricultural Research (ICAR) has commercialized non-genetically modified herbicide-tolerant (Ht) basmati rice varieties.<\/p>\n

ii) These varieties are engineered with a mutated ALS gene that allows for the direct application of the herbicide Imazethapyr.<\/p>\n

5. Scientific Research and Debates<\/strong><\/p>\n

i) Studies suggest that manual weeding at intervals (20 and 40 days after sowing) in DSR fields leads to better yields than using Imazethapyr.<\/p>\n

ii) ICAR supports eco-friendly practices like hand weeding over repeated herbicide use to control weeds and improve seed yield.<\/p>\n

6. Challenges with Herbicide Use<\/strong><\/p>\n

i) Imazethapyr specifically targets broadleaf weeds but does not affect all weed types.<\/span><\/p>\n

ii) The evolution of herbicide-resistant weeds poses a potential threat to rice production and food security<\/span>.<\/p>\n
