Reducing phytophthora fruit rot in eggplant and tomato fruits using rice straw and swine manure
Year: 2012
Type: article
Abstract: This study was conducted in a field plot to determine the effects of rice straw and swine manure on the incidence and severity of Phytophthora fruit rot on eggplant and tomato fruits in Nueva Ecija, Philippines.Treatments were based on the presence or absence of rice straw in combination with swine manure applied at 0 kg/m 2 , 0.5 kg/m 2 , and 1 kg/m 2 .Plots were artificially infested with P. infestans.Disease incidence and severity as well as marketable yields, were assessed at intervals.In both eggplant and tomato, lowest incidence and severity of Phytophthora fruit rot occurred in plots incorporated with rice straw (0.5 kg/m 2 ) + high swine manure (1 kg/m 2 ).The overall reduction on the incidence of the disease compared to plots without rice straw and swine manure was approximately 85% in eggplant and 72% in tomato.Similarly, the overall reduction on the severity in eggplant and tomato was 80% and 67%, respectively.Highest marketable yield was obtained in plants grown in plots incorporated with rice straw (0.5 kg/m 2 ) + high swine manure (1 kg/m 2 ).Other than the control, the incidence and severity were highest in eggplant and tomato plots where only rice straw was used as mulch.
