Disinfection of cowpea (vigna unguiculata) seeds on seedlings development.
The fast expansion of annual crops in recent decades with little phytosanitary management has led to the dissemination of several pathogens in the Brazilian cowpea-producing regions. Although, seed treatment is a common practice, there are no registered products for the cowpea and farmers apply the fungicides recommended for soybean cultivation. This study aimed to evaluate the influence of sodium hypochlorite and fungicidal treatments on the germination and initial development of seedlings of five cowpea cultivars under greenhouse conditions. Two experiments were established, one with seeds of five cultivars stored during 120 d, and another with newly collected seeds, disinfected or not with sodium hypochlorite, and treated with five fungicides.
