Seven fungicides were evaluated in vitro against Exserohilum turcicum causing leaf blight of maize The treatment mancozeb 0.25% and combination treatments of carbendazim and mancozeb i.e. saff 0.25% recorded the lowest percent disease index (PDI) reducing the disease by 73.0% and 72.1% respectively. The treatment which had a combination metriram + pyraclostrobin i.e. cabriotop 0.3% was found to...

Taiwanese isolates of Phytophthora infestans were examined for mating types and pathogenicity to tomato and potato. A total of 70 isolates, including 68 isolates from tomato and 2 isolates from potato, from six counties of Taiwan were all A1 mating type. Three tomato isolates of P. infestans caused only leaf blight of tomato, while two isolates obtained from potato were able to cause the diseas...

L.) are a popular horticultural crop that has been grown for centuries. One diseases target leaves shallot plant is Botrytis Walker. A microbial community being used reduce severity fungus Walker's disease. The goal this study was see how consortium affected leaf ...

Agricultural yield is mainly affected by differences in climatic conditions and seasonal diseases. There is a strong need of modern agricultural systems that identify disease in the crops. The goal of this study to design, develop and evaluate GA-SVM based methodology for automatic classification of pomegranate related diseases. This innovative method would be a boon to many and would have lot ...

In 2011, a leaf blight disease was observed on cosmos (Cosmos bipinnatus) leaves in Nonsan, Korea. The causal pathogen was isolated and identified based on morphological and molecular approaches. Morphological characteristics of the pathogen matched well with the Alternaria cosmosa and also easily distinguishable from Alternaria zinniae reported from cosmos seeds by producing branched beak. Phy...
