Evaluation of Different Fungi Toxicants against Yellow Rust Diseases on Bread Wheat (Triticum aestivum L.) in the Cold Arid Zone of Kargil, Ladakh (J&K), India

A field experiment was conducted to determine the efficacy of different triazole fungicides against yellow rust of wheat caused by Puccinastriiformis. The experiment field was divided in three part one part sprayed with propoconizole. Five fungicide (propiconazole 10EC, tebuconazole 25 EW, difenconazole 25 EC, hexaconazole 5EC andazoxystrobulin+ difenconazole were used in the experiment. All the fungicide treatment significantly reduced the disease intensity by 6.1% to 9.5 % as compared to control (35.5%). The minimum disease intensity (6.1%) was recorded in treatment where propoconizole before disease appearance and ozoxystrobulin +difenaconazole after disease appearance was sprayed fallowed by propiconazole and tebuconazole with disease intensity of 7.8 %. Whereas 8.2 percent disease intensity was recorded in treatment where propoconizole was again sprayed after disease appearance followed by hexaconazole (9.3%). Whereas, maximum disease intensity was recorded where propoconzole and hexaconazole was sprayed.
