Abstract: Cucumis sativus L is a member of the cucurbit family grown wildly for it edible fruits. Virus infection has been reported to be a major constraint to its production as over 60 plant viruses are known to infect this crop reducing the quality and quantity of yearly production. Symptoms of mosaic and mottle was observed on this crop during the 2019 growing season in Ehom, Cross River State, Nigeria. Infected leaf samples were collected and tested using host rang/symptomatology test, insect transmission test and gene sequence analysis. The virus was found to infect only members of the cucurbit family and was transmitted by Aphis spiraecola. A. citricida did not transmit the virus. ACP-ELISA detected the virus to be a potyvirus and result from gene sequence analysis showed that the virus shared 81 % sequence identity with Algerian watermelon mosaic virus. The virus was considered a strain of Algerian watermelon mosaic virus. This is the first report of this virus infecting Cucumis sativus in Nigeria.....

Abstract: Improving plant productivity still a challenge for researchers and administrations because yield losses caused by pathogenic fungi attacks of plant remains. This situation unfortunately highlights several problems, including food security. Phytopathogenic fungi are responsible of a range of diseases on a wide variety of herbaceous plant species. This study was addressed to test the influence of harvest periods alongside with Essential oil (Eo) from Arbuscular Mycorrhiza (AM) fungi lemongrass plant on the growth inhibition, susceptibility rates and enzymes activity on three phytopathogenic fungi in vitro. Poisoned food technique was used to determine inhibition capacity of mycelial growth, minimum inhibitory concentration (MIC), minimum fungicidal concentration, susceptibility....

Abstract: The present study is aimed to study the diversity of bacterial flora in the rhizosphere and rhizoplane of Abelmuscus esculentus (Okra) and Brassica oleracea var. Botrytis (Cauliflower) and their morphological and biochemical characterization. Rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms. The microbe- plant interaction in the rhizosphere can be beneficial, neutral, variable, or deleterious for plant growth. Rhizobacteria that exert beneficial effects on plant development are termed plant growth promoting rhizobacteria (PGPR). The rhizobacteria from rhizosphere and rhizoplane were isolated by serial dilution techniques and plating onto Nutrient agar medium. The isolates were subjected to various biochemical test. The results revealed that the population density of.......
