Frost and Black Blight Threaten Rabi Crops: Farmers Learn Protection Measures

• Rapidly changing weather in Nagaur and across the state poses a threat to Rabi crops from frost and Black Blight.
• Black Blight, affecting garlic, onions, and opium, causes yellow/brown spots that turn black, drying leaves and disrupting photosynthesis.
• To combat Black Blight, experts recommend spraying Carbendazim 12% and Mancozeb 63% WP after dew dries or in the evening.
• Frost, a 'silent killer' for mustard, coriander, potato, tomato, and chickpea, freezes water in plant cells, causing them to burst.
• Protection against frost includes chemical sprays (dilute sulfuric acid, Thiourea), light irrigation, and creating smoke barriers.

Why It Matters: Farmers must implement timely measures to protect Rabi crops from the damaging effects of frost and Black Blight.
