13. Common bean genotypes for agronomic and market-related traits in VCU trials
Value for Cultivation and Use (VCU) trials are undertaken when evaluating improved common bean (Phaseolus vulgaris L.) lines, and knowledge of agronomic and market-related traits and disease reaction is instrumental in making cultivar recommendations. This study evaluates the yield, cooking time, grain color and reaction to anthracnose (Colletotrichum lindem

14. Identification of Fusarium oxysporum f. sp. lactucae race 1 as the causal agent of lettuce wilt in Brazil
The objective of this work was to assess the virulence to lettuce cultivars and host specificity and to identify races of Fusarium oxysporum f. sp. lactucae (FOLac) isolates associated with lettuce wilt in Brazil. Thirty-one isolates identified based on morphology were inoculated in a set of lettuce cultivars for race determination. Plantlets of 'Elisa', 'Ve

15. Using AFLP-RGA markers to assess genetic diversity among pigeon pea (Cajanus cajan) genotypes in relation to major diseases
Resistance gene analog (RGA)-anchored amplified fragment length polymorphism (AFLP-RGA) marker system was used in order to evaluate genetic relationships among 22 pigeon pea genotypes with varied responses to Fusarium wilt and sterility mosaic disease. Five AFLP-RGA primer combinations (E-CAG/wlrk-S, M-GTG/wlrk-S, M-GTG/wlrk-AS, E-CAT/S1-INV and E-CAG/wlrk-A

16. EF-1α gene and IGS rDNA sequencing of Fusarium oxysporum f. sp. vasinfectum and F. oxysporum f. sp. phaseoli reveals polyphyletic origin of strains
The fungi Fusarium oxysporum f. sp. vasinfectum (Fov) and F. oxysporum f. sp. phaseoli (Fop) are important pathogens that cause wilt on cotton and common bean, respectively. In the present study, phylogenetic trees constructed with partial sequences of the translation elongation factor gene and ribosomal intergenic spacer region of Brazilian Fov and Fop stra

17. Evaluation of a cotton germplasm collection against Fusarium wilt race 3 isolates from Egypt
Pathogenic variation of 30 isolates of Fusarium oxysporum f. sp. vasinfectum (FOV) race 3 was evaluated on seedlings of the highly susceptible cotton cultivar 'Giza 74' in greenhouse assays. FOV isolates were clustered based upon their virulence patterns. The clusters of FOV isolates were not related to their geographic origins. Fifty-five experimental cotto

18. Induction of suppressiveness to Fusarium wilt of chrysanthemum with composted sewage sludge
The effectiveness of composted sewage sludge incorporated into Pinus bark-based substrate with or without biofertilizer, fish hydrolyzate, chitosan and Trichoderma asperellum was evaluated for the control of Fusarium wilt in chrysanthemum. The substrate was obtained from pots containing chrysanthemum plants killed by the pathogen. Half of the substrate was s

19. Screening of lettuce accessions for resistance to Fusarium oxysporum f. sp. lactucae race 1
Fusarium wilt caused by Fusarium oxysporum f. sp. lactucae (FOLAC) is one of the most important problems for lettuce growers because it causes major losses in production. To identify cultivars with potential for use in the management of the disease, 102 accessions were evaluated for resistance to isolates of race 1 of FOLAC. Initially, preliminary screening

20. Identification of passion fruit genotypes resistant to Fusarium oxysporum f. sp. passiflorae
This study aimed to characterize the resistance of 31 passion fruit (Passiflora sp.) genotypes to Fusarium oxysporum f. sp. passiflorae (FOP). About 20 seedlings of each genotype were inoculated by immersing the roots in a suspension of 10(6) macroconidia mL-1 for five minutes and then transplanting them into pots containing a mixture of soil and sterile sub

21. Common bean cultivar BRS Ametista with large Carioca grains and disease resistance
BRS Ametista is a common bean cultivar with Carioca grain and yields similar to cultivar Pérola, but with larger grain size, resistance to anthracnose and Fusarium wilt. It is recommended for 18 states in all regions of Brazil and can be planted on over 95% of the area used for common bean in the country.

22. BRS Notável: a medium-early-maturing, disease-resistant Carioca common bean cultivar with high yield potential
BRS Notável is a common bean cultivar with carioca grain, suitable for cultivation in 20 Brazilian states. It is a medium-early-maturing cultivar, with an average yield of 2,261 kg ha-1, 8.5% higher than the controls, a high yield potential (4,472 kg ha-1), lodging tolerance and resistance to anthracnose, fusarium wilt, common bacterial blight, and curtobac

23. Inoculation of tomato seedlings with Trichoderma Harzianum and Arbuscular Mycorrhizal Fungi and their effect on growth and control of wilt in tomato seedlings
A green house study was conducted to investigate the ability of an isolate of Trichoderma harzianum (P52) and arbuscular mycorrhizal fungi (AMF) in enhancing growth and control of a wilt pathogen caused by Fusarium oxysporum f. sp. lycopersici in tomato seedlings. The plants were grown in plastic pots filled with sterilized soils. There were four treatments
