The use of resistant cultivars is the main strategy to control Fusarium wilt on tomato, caused by oxysporum f. sp. lycopersici . This study aimed quantify incidence and distribution this disease in region Nova Friburgo, RJ, as well type resistance tomato three FOL races. Samples healthy wilted plants from 40 properties were evaluated for presence vascular discouloration. Seventeen races using a...

Fusarium wilt of banana always drives farmers to find new land for banana cultivation due to the comeback of the disease after a few cropping years. A novel idea for solving this problem is the continuous application of bioorganic fertilizer (BIO), which should be practiced from the beginning of banana planting. In this study, BIO was applied in newly reclaimed fields to pre-control banana Fusa...

Wilt caused by Fusarium oxysporum f.sp. ricini (Wr) Gordon is one of the major yield losing diseases in castor. Cultivating wilt resistant cultivars is an effective strategy to control the disease. Utilization of diverse sources of stable resistance is a prerequisite for durable resistance breeding. The experiment was conducted to identify genetically diverse resistant sources in castor germpla...

Abstract Endophytic bacteria serve key roles in the maintenance of plant health and growth. Few studies to date, however, have explored antagonistic growth-promoting (PGP) properties Prunus cerasifera endophytes. To that end, we isolated endophytic from P. tissue samples used a dual culture plate assay screen these microbes for activity against Verticillium dahliae, Botryosphaeria dothidea, Fus...

Since gene expression approaches constitute a starting point for investigating plant-pathogen systems, we performed a transcriptional analysis to identify a set of genes of interest in tomato plants infected with F. oxysporum f. sp. lycopersici (Fol) and Tomato Mosaic Virus (ToMV). Differentially expressed tomato genes upon inoculation with Fol and ToMV were identified at two days post-inoculat...

Bennett, R. S., Spurgeon, D. W., DeTar, W. R., Gerik, J. S., Hutmacher, R. B., and Hanson, B. D. 2011. Efficacy of four soil treatments against Fusarium oxysporum f. sp. vasinfectum race 4 on cotton. Plant Dis. 95:967-976. Fusarium wilt, caused by race 4 of Fusarium oxysporum f. sp. vasinfectum, is a critically important disease problem in California cotton (Pima, Gossypium barbadense; Upland, ...

The methods of spread of cotton wilt caused by Fusarium vasin» fectum Atk. have received considerable attention from investigators. It has long been suspected that insects frequently play a part in the local spread of cotton wilt. During 1933 and 1934 the writers sought to obtain definite information on the possibility of spread of wilt through the fecal pellets of insects that normally feed on...

In this paper, copper (II) citrate Cu3(C6H5O7)2 was successfully synthesised in an aqueous solution. The factors for the synthesis process such as temperature and molar ratio of reactants were investigated. structural, properties composition characteristics elements investigated evaluated by X-ray diffraction pattern (XRD), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive (EDX)...

Ralstonia solanacearum, which causes bacterial wilt of diverse plants, produces copious extracellular polysaccharide (EPS), a major virulence factor. The function of EPS in wilt disease is uncertain. Leading hypotheses are that EPS physically obstructs plant water transport, or that EPS cloaks the bacterium from host plant recognition and subsequent defense. Tomato plants infected with R. solan...
