Major diseases in grafted cacti have been reported and Fusarium oxysporum, Bipolaris cactivora, Phytophthora spp. and Collectotrichum spp. are known as causal pathogens. These pathogens can lead to plant death after infection. Therefore, some European countries have quarantined imported cacti that are infected with specific fungal pathogens. Consequently, we developed PCR detection methods to i...

Si ngh A, Islam MN (2010) In vitro evaluation of Trichoderma spp against Phytophthora nicotianae. Int. J. Expt. Agric. 1(1), 20-25. The Blank sank disease of tobacco caused by Phytophthora nicotianae results in considerable loss of the crop. This lab study aimed to investigate antagonistic activity of Trichoderma spp isolates against P. nicotianae. Three isolates of Trichoderma harzianum and on...

Phytophthora root rot causes extensive damage to feeder roots of avocado. If uncontrolled, it results in a progressive decline in tree health and the eventual death of the tree (12, 14, 15). Phytophthora root rot is a major factor limiting avocado production world wide. Effective control of Phytophthora root rot of avocado has been achieved with fosetyl-al (Aliette® Rhone-Poulenc, aluminum tris...

Se evaluaron caracteres morfológicos esporangios clamidosporas, formación estructuras sexuales, patr...

The investigation was carried out at the laboratory of Plant Pathology Department, SASRD, Nagaland University (NU), Medziphema Campus, Nagaland, India during year kharif (August-October, 2020) to evaluate antagonistic potentiality Trichoderma spp. (T. harzianum, T. asperellum and virens) against three diseases pigeonpea viz. Alternaria leaf spot (Alternaria alternata), Collar rot (Sclerotium ro...

Citrus production is declining worldwide due to several biotic and abiotic factors. The diseases caused by Phytophthora spp. present major economic risks since they are soil-borne spread quickly if environmental conditions favorable, or irrigation poorly managed. species in all citrus-producing areas around the world causing significant losses crop yield affecting tree health. Bark infection, d...

Molecular genetics approaches in Phytophthora research can be hampered by the limited number of known constitutive promoters for expressing transgenes and the instability of transgene activity. We have therefore characterized genes encoding the cytoplasmic ribosomal proteins of Phytophthora and studied their suitability for expressing transgenes in P. infestans. Phytophthora spp. encode a stand...

Foot rot disease (Phytophthora capsici) causes severe economic losses to cultivators of black pepper. Fungicides used for managing the adversely affect export potential product due their residual toxicity. Endospore-forming bacterial strains, Bacillus amyloliquefaciens VLY24, pumilus VLY17, and velezensis PCSE10 were evaluated growth promotion suppression in pepper nursery at two locations Kera...
