A Case Study of Occurrence and Intensity of Stripe Rust due to Planting Dates in Layyah District

Abstract

The impact of cultural practices like varietal selection, sowing time and date on disease severity and incidence of wheat stripe rust was recorded from twelve different locations of three tehsil’s of district Layyah. Survey results showed that Galaxy, Sehar 2006, Fareed 2006, Punjab 2011 and Ujala were the commonly practiced sown varieties in Layyah district. It was found that almost all sown varieties were vulnerable to the rust pathogen showing zero resistance. Disease severity of wheat stripe or yellow rust in three tehsil’s of district Layyah was found maximum (73.33%) on location-1 in tehsil Layyah, while in tehsil Karor Lal Esen maximum severity was recorded on location-3 (74.44%) and in tehsil Chobara, maximum severity was noted at location III with (66.66%). Overall disease severity of wheat stripe or yellow rust in three tehsil’s of district Layyah was pragmatic maximum (76.49%) in tehsil Karor Lal Esen, followed by tehsil Layyah and Chobara with (72.12%) and (64.11%) respectively. Sowing of wheat at different dates in the month of mid October, first week of November, mid November and the last week of November showed a great impact on the disease severity of stripe or yellow rust of wheat. Maximum disease incidence 67.11 % was recorded on those locations where the sowing was in practice in last week of November by the farmers. This varietal selection of wheat sown in different fields showed a big impact on the disease severity of wheat stripe rust. This information may provide a source for the better management tactics of the disease in future.
