Rust (Hemileia vastatrix) is the most important coffee disease in Brazil. Organic production has increased country and a research program aimed to develop alternatives chemicals for control was required. Seven bacterial isolates, isolated from organic plantings selected greenhouse tests, were evaluated under commercial crop conditions 2005 (Experiment 1) 2005/2006 2), Machado, MG, Ten treatments consisting of seven copper hydroxide, calcium silicate water applied as three or four monthly...
This study aimed to characterize the resistance of 31 passion fruit (Passiflora sp.) genotypes Fusarium oxysporum f. sp. passiflorae (FOP). About 20 seedlings each genotype were inoculated by immersing roots in a suspension 10(6) macroconidia mL-1 for five minutes and then transplanting them into pots containing mixture soil sterile substrate. They evaluated daily 120 days occurrence wilt symptoms death. These data used calculate area under disease progress curve, survival analysis grouping....
Abstract Fusarium oxysporum f. sp. cubense (Foc) causes Panama disease or wilt of bananas. The association between soil-inhabiting fungi and nematodes can increase the severity symptoms suppress resistance plants to diseases. In this study, interaction Foc race 1 Radopholus similis , a burrowing nematode that parasitizes banana plants, was analyzed using one moderately susceptible cultivar seven resistant cultivars banana. Two isolates differed in virulence were tested. analyses stained...
Fusarium wilt caused by oxysporum f. sp. cubense (Foc) is one of the most destructive diseases in banana farming worldwide. Knowledge factors genetic diversity and virulence pathogen contributes to development resistant cultivars management strategies based on exclusion. In this study, phenotypic traits such as aggressiveness a sample 52 Foc isolates, were analyzed their relationship presence putative effectors gene SIX (Secreted Xylem) pathogenicity homologues, verified. According...
Bananas, a staple food globally and key agricultural commodity, face severe threat from the fungus Fusarium oxysporum form specialis cubense (Foc), significantly impacting production. Genetic improvement to develop resistant cultivars stands out as crucial strategy mitigate this disease. This study focused on assessing recommending enhanced diploid banana varieties for resistance against Foc subtropical race 4 (ST4) 1 (R1). Twenty-five improved diploids developed by Embrapa, Brazil,...
Fusarium oxysporum f. sp. passiflorae W.L. Gordon (FOP) is one of the most important fungal pathogens passion fruits. Understanding molecular variation isolates from different areas utmost importance. Molecular fingerprinting on 14 FOP were conducted using AFLP markers (Amplified Fragment Length Polymorphism), and their genetic variability estimated. Twenty-five primer combinations selected for amplification cubense W.C. Snyder & H.N. Hansen (FOC), resulting in 99% polymorphic fragments,...
Panama disease, caused by Fusarium oxysporum f. sp. cubense (Foc), is ranked among the most destructive diseases of banana. The use resistant varieties desirable and effective control measure. Information on pathogen population structure essential, as durability resistance cultivar deployment are strongly linked to this structure. In study, 214 Foc isolates from different banana producing states in three regions Brazil (northeastern, southeastern southern) were analysed. Initially, nine...
Abstract Black Sigatoka (black leaf streak disease) is caused by the fungus Mycosphaerella fijiensisMorelet. This phytopathogen colonizes banana leaves, resulting in reduced photosynthesis and decreased productivity. Fungicide applications are useful to control black Sigatoka; however, they increase production costs can have adverse environmental health impacts. The cultivation of resistant cultivars regarded as a more economically viable option. objective this study was perform diploid...
Organic compounds from the compost of agricultural waste have been increasingly used in formulation substrates for fruit seedlings production. Microorganisms can enhance beneficial effects fertilizers on plant, but reports use endophytic strains to promote banana plant growth are rare. The goal this study was investigate ideal mixture soil and organic compound with Bacillus sp. Trichoderma asperellum inoculations optimal nutrient content seedlings. A Greenhouse experiment arranged a...
– Fusarium wilt, caused by oxysporum f. sp. cubense (Foc), is one of the most destructive diseases affecting banana crops worldwide. Therefore, development resistant cultivars a promising alternative to mitigate effects disease on plantations. The objectives this study were induce somaclonal variation in Silk and Cavendish types select somaclones subtropical race 4, thereby enabling production fruit areas where present. Shoot clump apexes Grand Naine Maçã (Silk) grown MS medium. cultures...
Pseudomonas putida P286 and Bacillus thuringiensis B157 controlled coffee rust under greenhouse field conditions. Now we studied the mechanism(s) of antagonism both bacteria to Hemileia vastatrix. Bacterial effects on urediniospore germination disease severity were evaluated in experiments with six treatments: (i) growth broth, (ii) supernatant centrifugation, (iii) bacterial cell centrifugation re-suspension, (iv) UV inactivation bacteria, (v) 523 medium, (vi) saline solution. The...
Fusarium wilt caused by
The objective of this work was to identify sources resistance dry root rot induced by Fusarium sp. in cassava accessions. A macroconidial suspension (20 µL) 11 isolates inoculated roots, from 353 acessions plus seven commercial varieties. Ten days after inoculation, the total area colonized pathogen on pulp evaluated digital image analysis. Cluster analysis revealed presence five groups regarding resistance. lesion areas ranged 18.28 1,096.07 mm² for accessions BGM 1518 and 556,...
ABSTRACT Fusarium wilt (syn= Panama disease), caused by oxysporum f. sp. cubense (FOC), is one of the most destructive diseases banana, being genetic resistance main management strategy for this disease. Since pathogen constantly evolving to supplant resistance, new sources must be investigated improvement programs aiming developing varieties. The objective present study was identify from different accessions maintained in banana active germplasm bank (BAGB) at Embrapa Mandioca e...
