Abstract:
Stripe or yellow rust caused by Puccinia striiformis f. sp. tritici is one of the most important foliar diseases of wheat causing severe loss under favourable conditions. This disease occurs in epidemic form in cool and moist wheat growing regions. Weather factors play a major role in the incidence and severity of the crop diseases. This study is an attempt to assess the effect of different sowing dates on stripe rust of wheat disease development. The experiment was conducted on susceptible wheat variety PBW 343 grown under artificial epiphytotic conditions at Rajasthan Agricultural Research Institute, Durgapura (Jaipur) during 2020-21 and 2021-22. Significant variations in disease severities were observed among the crop planted at five different dates. The timely sown crop on 20^th November was found more vulnerable to stripe rust in comparison to early and late sown crops i.e. 10^th November, 30^th November and 10^th December.
