Abstract

In Mexico, the main production area for temporary wheat is located in the High Valleys of Central Mexico, where the linear rust (Puccinia striiformis f. sp. tritici Eriks) has become the main problem in recent years, being much more aggressive than leaf rust (Puccinia triticina Eriks). In order to know the most appropriate stage for the application of fungicides for the control of the disease, four commercial formulations and different protection strategies were used, seeking to expand the knowledge in the control of the linear rust in susceptible varieties and thus improve the production of bread wheat under temporary conditions. The present investigation was carried out during the spring-summer cycle, 2015 using the Nana F2007 variety in the municipality of Terrenate, Tlaxcala, Mexico. The best protection strategy was 2, which corresponds to the application of systemic fungicides 45 days after sowing (dds) and in anthesis (70 dds), which was associated with the highest yield. The fungicides that showed the best control over linear rust were the mixture of Axozistrobina+Propiconazole (QUILT®) and Tebuconazole (Folicur 250EW), with which the highest yield values and statistically similar effects were obtained. The results indicate that it is necessary to apply fungicides to control the disease, otherwise the yield losses could be 53% between strategies and up to 84% without application of fungicide.
