EFFECT OF CONVENTIONAL AND ALTERNATIVE PRODUCTS ON POSTHARVEST DISEASE CONTROL IN AVOCADOS Rev. Bras. Frutic.
Fischer,Ivan Herman; Moraes,Matheus Froes de; Palharini,Maria Cecília de Arruda; Fileti,Mirian de Souza; Cruz,Juliana Cristina Sodário; Firmino,Ana Carolina.
ABSTRACT Postharvest diseases constitute a serious problem for avocado commercialization. Thus, the present study aimed to evaluate the effect of conventional and alternative products in controlling diseases affecting ‘Hass’ avocados in the field and in the postharvest by carrying out physicochemical characterization of fruits subjected to postharvest treatments. In the field, besides the management adopted by the farmer, seven products were sprayed three times during fruiting for evaluation. Postharvest products were diluted in water or in oxidized polyethylene wax and shellac. Water treatments with potassium phosphite, Soil-Set®, chlorine dioxide, thyme essential oil, sodium bicarbonate, lemon grass essential oil and thiabendazole reduced the incidence...

Etiología y manejo de la pudrición de frutos de piña (Ananas comosus L. Merr.) en postcosecha. Colegio de Postgraduados
Sánchez Aguirre, María Dolores.
En el cultivo de piña (Ananas comosus L. Merr.) desde el 2011 se ha estado presentando una enfermedad de frutos en postcosecha de etiología desconocida, en el estado de Veracruz, México. Fusarium subglutinans, Fusarium verticillioides (sin. Fusarium moni¬liforme) y Fusarium oxysporum, identificados cultural, morfológica y molecularmente, se asocio con este problema en 84% de los aislamientos obtenidos de pudrición de frutos. Se realizaron pruebas de patogenicidad en frutos de piña en estado de madurez 1 de la variedad MD2. Los frutos mostraron la pudrición, caracterizada inicialmente la presencia de pequeñas manchas irregulares de color café claro en el pericarpio de los frutos, conforme avanzo la enfermedad la mancha irregular se torno de color café...

Propagation of Noble Dendrobium (Dendrobium nobile Lindl.) by cutting - doi: 10.4025/actasciagron.v35i4.15198 Agronomy
Venturieri, Giorgini Augusto; UFSC - Universidade Federal de Santa Catarina; Pickscius, Fabiano José; Centrais de Abastecimento do Estado de Santa Catarina S.A..
The Noble Dendrobium orchid (Dendrobium nobile Lindl.) is an ornamental species usually propagated by leaf axillary shoots called “Keikes”, but cutting is possible although, many do not produce leaves or roots and eventually rot. To increase the proportion of successful stalk cuttings, two substrates were evaluated in the present study (gravel and a 1:1 tree-fern shredded trunk:palm seed mixture) in interaction with the application of nitrogen fertilizer (urea 2 g L-1) and a commercial leaf fertilizer made from kelp seaweed (“Kelpak” a 2 mL L-1). Only water was applied for the control treatment. The evaluated parameters included the proportion of successful cuttings, vigor, the proportion of rotten stalks, the number of roots/plant and root length/per...

Systemic resistance induction in ‘Ortanique’ tangor Rev. Bras. Frutic.
Kirinus,Marines Batalha Moreno; Silva,Pricila Santos da; Barreto,Caroline Farias; Oliveira,Roberto Pedroso de; Malgarim,Marcelo Barbosa.
Abstract This study aimed to evaluate the quality of ‘Ortanique’ tangor, in the post-harvest and refrigerated storage after application of pre-harvest resistance inducers, in the 2015 and 2016 crops. The experimental design in the field was in completely randomized blocks, in a single factorial scheme. The treatment factor was composed of the following resistance inducers [without inducer, selenium (Se), silicon (Si), acibenzolar-s-methyl (ASM), methyl jasmonate (MeJa), thiamethoxam (TMT) and imidacloprid (IMI)]. In the laboratory, the design used was the same as that established in the field, but in a two-factorial scheme, where factor A was composed of the same inducers and factor B, for the storage period [zero (fruits that were not submitted to...
