Nowadays, Egypt is the largest wheat importer in the world and consumes an extensive amount of it. To decrease the gap between production and consumption and increase the yield, we need to control wheat diseases, especially stripe rust, due to its major damage to wheat. Further, we need to advise farmers as early as we can to control and treat them. The paper proposed an interactive intelligent system to monitor, predict and give the correct advice at the right time to farmers. This system is called MISSR (Mentoring Interactive System for Stripe Rust). The system is considered an important means to effectively prevent risks in agricultural production. It also plays an important role in guiding farmers and decision-makers to plan and implement suitable practices to increase yield and mitigate stripe-rust disease. On the other hand, it can acquire relevant and timely information in the areas where this information or data is unavailable. To build this model for the wheat crop in Egypt, we used wheat experts’ knowledge and climate data API. MISSR is available as a mobile application to provide access for more farmers and increase its availability. Keywords: wheat; rust; Puccinia; mobile app; interactive system 1. Introduction Wheat is the major winter grain crop in Egypt. It represents about 10% of the agri- culture production in Egypt and about 20% of the total value of the agriculture imports. Wheat production in Egypt is not adequate for the urgent needs of people, thus more than 50% of the consumption is annually imported. The damage caused by rust diseases is considered one of the major obstacles facing the production of wheat crops. Stripe rust caused by Puccinia striiformis f.sp. tritici is a serious wheat disease that causes a severe economic loss in wheat production in many parts of the world including Egypt [1–4]. Stripe rust requires two distinct hosts. Since 2010, it has been considered to be macrocyclic rust, after the identification of Berberis spp. as an alternative host and elucidation of the complete life history of this rust pathogen for the first time by Jin et al. [5]. Briefly, it spends its Telial/uredinial stages on the primary host(s), including T. aestivum, however, it spends its pycnial/aecial stages on an alternate host(s), which mainly include Berberis spp. Fortunately, alternate hosts of P. striiformis do not exist in Egypt and its urediniospores cannot persist or survive in Egypt during the summer; nevertheless, the source of a primary inoculum is typically brought in by northern winds from foreign sources annually [6,7].
