Abstract: Anthracnose, caused by the fungus Colletotrichum gloeosporioides Linnaeus, is the most common pre-and postharvest disease of mango, causing economic losses of 30-60 percent in the production of fruit in tropical, subtropical countries. C. gloeosporioides is reported to infect a wide range of hosts and has become an increasingly significant pathogen affecting a variety of economically important crops throughout the world. Mango anthracnose management is a popular issue among farmers and agriculturists.

Abstract: Early blight (EB) caused by Alternaria solani is among the most devastating tomato diseases in Kenya. In this study, we collected 96 A. solani isolates from three counties in Kenya and characterized them using cultural features, conidial morphology, and genetic variation based on the 18S rRNA gene. Most colonies (45%) were greenish-white in colour with diameter ranging between 65.5-85 mm. Most colonies had concentric zonation (63%) and margins were mostly regular (53%). Conidia was ellipsoidal in most isolates (54%) with lengths ranging between 16.72-20.48 μm.

Abstract: Mycotoxins are toxic secondary metabolites of certain fungi species which has a capable of contaminating and reduce crops quality and quantity. Maize is one of the most important crops which is subjected to contamination by many species of mycotoxigenic fungi both before and after harvest.

Abstract: Tomato became the most profitable crop, providing small-scale farmers with a higher return than other vegetable crops in Western parts of Ethiopia. However, the national average tomato fruit output was frequently poor. Farmers, on the other hand, experience poorer yields due to biotic factors and fertilization that isn't up to snuff.

Abstract: Rice blast (Pyricularia oryzae Cavara) is the most destructive rice disease threatening rice production everywhere rice grows in the world. Use of resistant variety is effective and economical alternative for disease management. In the present study, 12 upland rice varieties viz. Adet, Andassa, Fofifa, Getachew, Hidassie, Kokit, NERICA 12, NERICA 13, NERICA 3, NERICA 4, Superica-1 and Tana were evaluated against rice blast at Pawe on-station and on-farm under

Abstract: Cassava brown streak disease (CBSD) affects cassava growth and production with resultant foliar symptoms and storage root necrosis causing significant economic losses to farmers. The disease is caused by either Cassava brown streak virus (CBSV) or Uganda cassava brown streak virus (UCBSV), both vectored by whitefly, Bemisia tabaci. Cultivation of CBSDfree or resistant cassava genotypes offers the most long term sustainable CBSD management. Through a field survey, the
