Essential oils of Lippia sidoides, gracilis and their main chemical components were investigated for in vitro control Thielaviopsis paradoxa. Mycelial growth a number pathogen conidia inhibited by the essential oil L. sidoides at all concentrations tested (0.2; 0.5; 1.0; 3.0 µL mL-1). contained 42.33% thymol 4.56% carvacrol, while 10% 41.7% carvacrol. conidial production T. paradoxa completely 0.3 m-1 concentration. The results suggest that could potentially be used controlling coconut stem bleeding.
In February of 2004, at "Platô de Neópolis", Sergipe, Brazil, about 50 coconut plants were found bearing symptoms a disease not yet recorded in Brazil.The trunk diseased exhibited reddish-brown or rust��colored liquid bleeding from scars.Inside the stem, tissues under lesions rotting and turned brownish-yellow to black.Diseased palms had reduced growth three four months after first noticed affected died.A fungus was isolated identified as Thielaviopsis paradoxa.Healthy inoculated with...
Stem bleeding disease (resinosis) of coconut palm is caused by Thielaviopsis paradoxa and very important in the state Sergipe, Brazil. Understanding epidemiological behavior essential for establishing more efficient control strategies. Thus, we characterized temporal progression spatial distribution stem a commercial orchard under conditions natural infection area Neopolis, Sergipe. Three plots with 729 plants each were selected evaluated every two months incidence. In analysis,...
Abstract Peanut seeds were tested by the enzyme-linked immunosorbent assay (ELISA) for peanut stripe virus without affecting their viability. A portion of cotyledon (0.02–0.05 g) was removed from end seed opposite radicle and triturated in an antigen buffer. Virus frequently detected extracts cotyledons embryos but seldom testa. Portions one infected ten could be detected. Correlations among ELISA, infectivity assays, growing out tests obtained. The ELISA technique has advantage detecting...
The significance of root transmission the red ring nematode (Rhadinaphelenchus cocophilus) to coconut palms (Cocos nucifera) was investigated in a screen-house experiment. Transmission by contact occurred seven 15 plants growing around five inoculated plants. In another experiment, each plant became infected when suspension placed on mechanically damaged roots. Young seedlings planted hole where previously diseased were did not develop typical symptoms disease (.)
RESUMO O objetivo do trabalho foi avaliar a eficiência fungicida Ciproconazole (bula:100 g i.a/litro) no controle de doenças foliares e subsequente aumento da produtividade coqueiro nas condições Nordeste Brasileiro. experimento conduzido município Una, BA, durante dois anos com plantas variedade Anão Verde Brasil 20 idade, recebendo uma adubação convencional. Estas estavam naturalmente infectadas pelas doenças: Lixa Pequena, Grande Queima das Folhas. tratamento utilizado aplicação tronco,...
Stromata colonization of Sphaerodothis acrocomiae causal agent the coconut large verrucosis by Acremonium persicinumThe factors affecting biological control (Sphaerodothis acrocomiae) coconuts (Cocos nucifera) with utilization hiperparasite fungus persicinum were studied.This is found mainly in rainy season (April-august) colonizing stromata as well small verrucosis.On culture produces a fine mycelium, single, small, hyaline conidium and on PDA has purplish color.The 10 7 conidia per ml...
