Several species of Septoria are associated with leaf and fruit spot of pistachio (Pistacia vera), though their identity has always been confused, making identification problematic. The present study elucidates the taxonomy of the Septoria spp. associated with pistachio, and distinguishes four species associated with this host genus. Partial nucleotide sequence data for five gene loci, ITS, LSU,...

A leaf spot of field corn was shown to be caused by the bacterium Pseudomonas andropogonis. Leaf spot symptoms were observed over 3 years in several States. Inoculation of corn by vacuum infiltration of the bacteria was necessary to reproduce field symptoms. Plant Dis. Reptr. 62: 213-216. A bacterial leaf spot disease of different cultivars of field corn was observed in early summer of 1973, 19...

Among foliar diseases Leaf spot, yellow mosaic virus (YMV) and Urd bean leaf crinkle (ULCV) are destructive of mash (Vigna mungo) in Pakistan. Incorporation resistance against biotic stress plants is traditional strategy crop improvement through breeding. Effective breeding for stresses entails readily accessible resistant germplasm. 67 genotypes were evaluated multi disease was tested two cons...

Due to the increased importance of angular leaf spot of common bean (Phaseolus vulgaris) in Brazil, monitoring the pathogenic variability of its causal agent (Phaeoisariopsis griseola) is the best strategy for a breeding program aimed at developing resistant genotypes. Fifty one isolates of P. griseola collected in five Brazilian States were tested on a set of 12 international differential cult...

The primary diseases affecting Zingiberaceae plants include ginger plague, spot blotch, anthracnose, leaf spot, blight, and soft rot. Insect pests that pose a threat to these encompass root-knot nematode disease, drilling bugs, beet nightshade moths, mesquite, thrips, aphids. This article aims summarize the defining features of principal as well their control methods. intention is offer theoret...

The bacterial spot of tomato, caused by Xanthomonas spp., is a very important disease, especially in the hot and humid periods of the year. The chemical control of the disease has not been very effective for a number of reasons. This study aimed to evaluate, under greenhouse conditions, the efficacy of leaf-spraying chemicals (acibenzolar-S-methyl (ASM) (0.025 g.L(-1)), fluazinam (0.25 g.L(-1))...
