“…Incidence was obtained by the number of fruits affected by repetition, expressed in percentage by treatment. For the severity variable, the diagrammatic scale developed by (Moraes, Zambolim, & Lima, 2008) with disease severity ranging from 0.5 to 64% was used. Due to the fact that variables were discrete, the basic hypotheses were tested for the analysis of variance, additivity, error normality and variance homogeneity.…”

Alternative forms of disease control in fruits have been researched in an attempt to minimize the negative effects of chemical control on men and environment. The aim of this study was to determine the best concentration of essential oils to control the development of Colletotrichum musae and anthracnose intensity in ‘Prata Anã’ banana. In order to inhibit germination, mycelial growth and sporulation, four essential oils of clove (Eugenia caryophyllus), tea tree (Melaleuca alternifolia), thyme (Thymus vulgaris) and ginger (Zingiber officinale) species were used at concentrations of 2, 4, 6 and 8 μL. In fruits, the same essential oils were applied at concentrations of 80, 160, 240 and 320 μL to evaluate the incidence and severity of anthracnose. Clove and thyme oils were the most efficient in inhibiting mycelial growth, germination and sporulation at all concentrations tested. The volatile compounds present in clove and thyme oils provide complete inhibition of fungal growth. Tea tree and ginger oils have the ability to suppress anthracnose in ‘Prata Anã’ banana. Concentrations of 160 μL of ginger oil, 160 and 240 μL of tea tree oil reduced the anthracnose severity in fruits. Ginger and tea tree essential oils have the potential to control banana anthracnose, reducing the anthracnose incidence in fruits by 48% and 24%, respectively.

“…CPMMV was first reported on cowpea in Ghana [1], and subsequently reported from several tropical regions of Africa [2,3,4,5,6], Asia [7,8,9,10], Brazil and Argentina [19,20], as well as from the Ivory Coast [21]. …”

Yardlong bean (Vigna unguiculata subsp. sesquipedalis) plants with virus-like systemic mottling and leaf distortion were observed in both experimental and commercial fields in Aragua State, Venezuela. Symptomatic leaves were shown to contain carlavirus-like particles. RT-PCR analysis with carlavirus-specific primers was positive in all tested samples. Nucleotide sequences of the obtained amplicons showed 84%–74% similarity to corresponding sequences of Cowpea mild mottle virus (CPMMV) isolates deposited in the GenBank database. This is the first report of CPMMV in Venezuela and is thought to be the first report of CPMMV infecting yardlong bean.

“…La temperatura de 55ºC se descartó, por los daños provocados en la cáscara, no obstante, en banano 'Prata-Ana'; Moraes et al (2006) afirman que un tratamiento de termoterapia de 56ºC por 6 min produce una disminución de lesiones en la cáscara. Para la ejecución de este ensayo se utilizó el cultivar 'Valery' (Musa AAA), lo cual sugiere que es más sensible que el cultivar 'Prata-Ana' (Musa AAB) a los tratamientos térmicos.…”

Con el objetivo de evaluar el efecto de la temperatura del agua y el tiempo de inmersión sobre la secreción de látex por la corona de gajos recién conformados de frutos de banano, se realizaron 2 experimentos con racimos de 12 semanas de edad (floración-cosecha) del cv. Valery (Musa AAA, subgrupo Cavendish). En el experimento 1 se evaluaron 4 temperaturas del agua: 25, 35, 45 y 55°C y, 4 tiempos de inmersión: 5, 10, 15 y 20 min en conjunto con un tratamiento testigo comercial. En el experimento 2 se evaluó unicamente la temperatura del agua a 45°C y 2 tiempos de inmersión: 10 y 20 min. En este experimento se incluyó un tratamiento testigo comercial (frutos tomados de la línea de empaque de la finca) y otro tratamiento testigo conformado por frutos cuyos gajos fueron empacados inmediatamente después de la separación del racimo (testigo absoluto). En ambos experimentos la inmersión de los frutos en agua caliente se realizó inmediatamente después que las manos fueron seccionadas del racimo y conformadas en gajos. En ambos experimentos no hubo maduración prematura durante el periodo de simulación de transporte que fue de 15 días. En el experimento 1 los tratamientos expuestos a 55°C, presentaron daño severo de quemadura en la cáscara. En el experimento 2 no se afectó la firmeza (p > 0,2685), aunque hubo diferencias estadísticas en el color de la cáscara (p < 0,0145) y en los sólidos solubles (p > 0,0001). El tratamiento de inmersión de 45°C por 10 min demostró que puede ser tan efectivo en la remoción del látex de la corona de gajos recién conformados de frutos de banano como el tratamiento comercial, basado en la inmersión sucesiva de los frutos en depósitos de agua circulante y la posterior aplicación de fungicidas y cicatrizantes.
