Efeito do ecolife-40 no controle da vassoura-de-bruxa (Crinipellis perniciosa) do cacaueiro
The objective of this paper was to evaluate in vitro and in vivo the effects of the product Ecolife on C. perniciosa.Inhibition of basidiospores germination and mycelial growth were studied in laboratory, by using several concentrations of the product. The results showed that Ecolife at 100 and 500 ppm caused 100% of inhibition on the germination and on the mycelial growth, respectively. As to the protective action there was a reduction of the incidence of disease on the treated seedlings that varied from 38,4% to 92,3%. Systemic action was observed when seedlings treated and further on prunned and inoculated showed less plants infected (30%) when compared to the control (60%). Fungitoxic substances derived or induced by Ecolife were able to inhibit the mycelial growth of C. perniciosa.
