Yellow rust shows as yellow-orange powdery stripes along the leaf veins, usually starting in patches in cool, cloudy, humid weather in December to February. Scout fields regularly, especially near borders and shaded areas. As soon as you see the first stripes, spray a triazole fungicide such as propiconazole 25 EC at 200 ml per acre or tebuconazole, in 200 litres of water per acre, and repeat after 15 days if needed. Do not wait, since rust spreads fast. The best long-term protection is growing resistant varieties like DBW 327, DBW 303 or PBW 826. Remove volunteer wheat plants that carry the fungus between seasons. Follow the product label for dose and pre-harvest interval, and consult your local KVK if you are unsure.

Last year yellow rust hit my field in Patiala after a foggy week. I sprayed propiconazole at the first sign and it stopped spreading. Catch it early.

Watch the patches near the field bunds and under tree shade first; rust almost always starts there for me. I walk those spots every few days in January. Spotting the first stripes early is half the battle.

In our area the agriculture department sends rust alerts on the cool, humid weeks. I keep a small stock of fungicide ready so I can spray the same day I see it, instead of running to the shop while it spreads.

Cover the leaf well, including the underside, with a flat-fan nozzle and enough water. A rushed light spray gave me poor control once. Repeat after about 15 days if the weather stays favourable for rust.

The cheapest fix is choosing a resistant variety in the first place. Since I shifted to DBW 327 and DBW 303 I rarely need to spray for yellow rust, while my old HD-2967 plot still gets it. Variety choice saves money every year.
