Various synthetic substances were used to control this disease. Commercial fungicide products have been used throughout the world. Currently, the following active ingredients are labeled for stripe rust control in Morocco: propiconazole, azoxystrobin, propiconazole in combination with trifloxystrobin, strobilurin and azoxystrobinin in combination with propiconazole. These fungicides labeled with different active ingredients give growers choices to use and can reduce the selection pressure in the pathogenic fungus to develop resistance to the chemicals.

Get an original essay The importance of fungicide use was demonstrated in field experiments near Pullman Washington during successive growing seasons from 2002 to 2012. They were conducted to improve chemical control of stripe rust for major cultivars grown commercially with various levels of resistance. The results of this study demonstrated that fungicide application reduced AUDPC (area under the disease progress curve) by more than 80% in both susceptible winter wheat and susceptible spring wheat compared to untreated controls. The reduction in AUDPC depends on the duration and severity of the disease. Tilt (propiconazole) was used during this study and became the standard fungicide to control stripe rust during this period. Triadimenfon (Bayleton) has been used extensively to control wheat stripe rust in China. The timing of spraying fungicides is critical to effective stripe rust control. Viljanen-Rollinson et al. (2006) revealed that the use of fungicides early in the growing season leads to better disease control. However, the use of fungicides adds high production costs to wheat production, which is a burden for many farmers, especially in developing countries. It causes numerous negative health and environmental problems. Furthermore, repeated applications can lead to the selection of fungicide-resistant strains of the pathogen. Cultural methods Cultural methods provide another strategy to partially control wheat stripe rust. Using a variety of cultural practices significantly increases existing sources of resistance. Consequently, crop management in terms of a combination of crop choice, timing of planting, and removal of wild grains can provide effective stripe rust control. Stripe rust requires green material to survive from one season to the next, it is known as “green bridge”. ”. The removal of wild plants (the Green Bridge) that will favor the survival of stripe rust is an effective control measure for epidemics resulting from endogenous inoculum. Planting a mixture of wheat varieties with different resistance backgrounds can significantly reduce disease pressure and can also increase or stabilize wheat yield. Mechanisms by which cultivar mixtures suppress disease may include dilution of spore density due to increased spacing between susceptible plants, a physical barrier created by resistant plants in the canopy that disrupts spore movement, and induced resistance. The challenge of.
