![]() ![]() viride must be evaluated and tested against coffee wilt disease in vivo and in field condition in different agro-ecological zones of coffee growing regions, in order to apply biocontrol agents in large areas to manage F. This is one of the most widespread and common disease of bulbs. viride have potential to be used as biocontrol agents for inhibition of mycelial growth of F. Similarly, in vitro evaluation of the culture filtrates showed an average of 63.6% mycelial growth inhibition by T. Losses have been heavy at times because infections invisible at time of. The disease was manifested by characteristic symptoms of Botrytis blight as spots on leaf, flower bud, flower, stem and corm. da in 1940 and has caused outbreaks of leaf blight and flower rot in one or more sections of the State each winter since 1942. In 2013-2014 crop seasons, botrytis leaf blight of gladiolus appeared as a new disease in farmers’ fields in Jashore regions 7. viride was found to be more efficient than T. of Botrytis are reported to attack gladiolus in Europe and North America but in Florida the only species important on gladiolus is B. viride with concentrations of 3ml, 4ml and 5ml resulted in radial growth inhibition of the test pathogen. Use of the cell free culture filtrates of T. Because the disease can result in plant death, Botrytis blight may have a significant impact on the establishment and yield of this crop in the field, especially. in Florida (2), but this is the first report of Botrytis blight on Hibiscus spp. As a postharvest disease, this fungus can cause gray mold of many fruits and. rose, snapdragon, stock, tulip), bulb rot of amaryllis, corm rot, leaf spot, and stem rot of gladiolus (Agrios, 1988). The minimum percent of mycelial growth inhibition (53.7 %) was observed by T.viride on isolate Fx.16. Botrytis gray mold blight has been recorded on H. Botrytis diseases are very common and widely distributed on vegetables, ornamentals, fruits, and field crops throughout the world (Agrios, 1988). The result showed that use of Trichoderma spp caused a radial mycelial growth inhibition of pathogen by 66.2% (Fx.20) and 70.9% (Fx.22), respectively. The ability of Trichoderma harzianum and Trichoderma viride to inhibit mycelial growth of F. The isolation was made from five Arabica coffee (Coffea arabica) trees with severe symptoms of coffee wilt disease. Rust, on the other hand, causes orange or brown spots on the leaves. Fusarium wilt causes the plant to wilt and die, while botrytis blight causes brown spots on the leaves and flowers. The development and spread of this disease is. Some of the common diseases that affect gladiolus include fusarium wilt, botrytis blight, and rust. ABSTRACT: Isolates of Fusarium xylarioides, the causative agent of coffee wilt disease, were obtained from five coffees growing woredas in south western Ethiopia. Botrytis blight caused by Botrytis gladiolorum is the most devastating disease under North Indian conditions.
