O feijão-caupi possui grande importância por fazer parte do hábito alimentar da população e ser uma das principais fontes de renda emprego. As doenças estão entre os fatores limitantes produtividade feijão-caupi, enfermidades que acometem ao é causada pelo fungo Macrophomina phaseolina. Em busca um desenvolvimento agrícola sustentável, o uso agentes controle biológico considerado alternativa vi...

charcoal rot disease, caused by macrophomina phaseolina has become a restrictive agent for annual crops in iran. the disease incidence reaches up to 90 percent in some infested areas. high air temperature and drought stress associated with this disease, are the main factors for increasing the disease incidence and severity. in order to isolate the pathogenic agents, pieces of infected root and ...

Macrophomina phaseolina is a highly problematic fungus that causes diseases in hundreds of plant species. In order to search for an alternative chemical fungicides the control this devastating pathogen, leaf extract Tabernaemontana divaricata was assessed M. phaseolina. Five concentrations methanol viz. 1, 2, 3, 4 and 5% (w/v), were checked against All these significantly suppressed fungal grow...

A Basidiomycota endomycorrhizal fungus, Piriformospora indica Verma, colonizes and promotes the growth of canola (Brassica napus L.) other Brassica crops can reduce diseases crops. Clubroot is an important disease caused by obligate, soil-borne pathogen Plasmodiophora brassicae Woronin. The effect P. on clubroot severity in was assessed replicated room studies. Seed treated with using a proprie...

Durante 1996 y 1997 se determinó la reacción de 166 genotipos frijol, en su mayoría cultivados, 237 germoplasma criollo poblaciones silvestres Phaseolus sp., con diversos orígenes, a un aislamiento altamente agresivo Macrophomina phaseolina condiciones invernadero Montecillo, México. Se identificaron mejorados, criollos sp resistentes M. phaseolina. Entre los sobresalen Amarillo Calpan, Manzano...

β-glucans are well-known modulators of the immune system in mammals but little is known about β-glucan triggered immunity in planta. Here we show by isothermal titration calorimetry, circular dichroism spectroscopy and nuclear magnetic resonance spectroscopy that the FGB1 gene from the root endophyte Piriformospora indica encodes for a secreted fungal-specific β-glucan-binding lectin with dual ...

An attempt was taken for the management of charcoal rot disease soybean caused by Macrophomina phaseolina using integration bio-agent with fungicide and organic amendment. Before going to field experiments, different in-vitro trials were conducted select a virulent isolate M. phaseolina, an effective antagonistic Trichoderma harzianum, suitable Among seven isolates MSP-4 selected as test pathog...
