Abstract: Downy mildew and powdery mildew are fungal diseases that cause diseases in plants. They are a major limiting factor for the production and productivity of crops and they are caused extensive quantitative as well as qualitative damage to the crops. These plant pathogens damage crop quality and yield worldwide. They cause a variety of symptoms on the affected plant parts and cause severe infections. The severity of downy and powdery mildew diseases varies and the variations depend on the environmental conditions. During favorable environmental conditions, they cause serious yield reduction. To minimize the losses caused by these fungal pathogens it is important to understand the pathogen biology, ecology, symptoms, damage, and differences between the two fungal pathogens that is important for identification and successful management methods. Hence, the objective of this review is to summarize current knowledge on the general biology, ecology, symptoms, damage, and control of downy mildew and powdery mildew of fungal diseases. Downy mildew and powdery mildew fungi cause significant diseases in a variety of economically important crops. These diseases often cause rapid and severe losses of crop yields. To reduce the losses caused by downy mildew and powdery mildew diseases, timely application of cultural, chemical, biological, host plant resistance, and integrated disease management methods are essential. Therefore timely application of management methods for mildew diseases is crucial for effective control. Specifically, integrated disease management serves as the most effective strategy to minimize the damage caused by these diseases, ultimately enhancing both the quantity and quality of crops globally.

Abstract: Traditional medicinal plants are vital to healthcare, especially in regions with limited modern medical access. In Ethiopia, these plants have significant cultural, ecological, and economic importance. The study aims to document the diversity of ‘’Samoa ETA’’ traditional medicinal plants, assess their ecological status, investigate traditional knowledge and practices, evaluate their economic value, and analyze policies regarding their conservation and sustainable use. A sample of 384 participants, including 10 traditional healers, 10 kebeles, and 4 woredas, will be selected from a population of 122,419. A stratified random sampling and systematic sampling method ensures representation across diverse ecological zones and socio-cultural groups. The research employs a multidisciplinary approach, combining ethnobotanical surveys, ecological assessments, and economic analyses. Ethnobotanical surveys will document the uses, preparation methods, and cultural significance of these plants. Ecological assessments will examine their distribution, abundance, and conservation status. A mixed-methods approach will integrate quantitative surveys analyzed using SPSS 26 and qualitative interviews thematically analyzed. Economic valuation will assess the monetary value and contribution to local livelihoods and national economies. The study aims to enhance understanding of the ‘’Samoa ETA’’ medicinal plant diversity, ecological status, and traditional knowledge. It will provide insights into their economic value, inform conservation strategies that respect local customs, and promote sustainable management practices benefiting both the environment and local communities. Ultimately, this research seeks to ensure the continued availability and use of traditional medicinal plants for current and future generations.
