Nematicidal Activity of the Fungicide Ethazole

R. Rodriguez-Kabana, Peggy S. King

Abstract


The nematicidal activity of the fungicide ethazole was studied under greenhouse conditions in which a nematode-infested, Norfolk sandy loam was planted to cotton (var. = 'Rowden'). At planting time, the fungicide was incorporated in the soil at rates of 0-100 mg/kg soil. When assayed 4 weeks after planting, plant-parasitic nematodes in soil and roots occurred in decreasing numbers with increasing concentrations of the fungicide; the degree of control obtained was from 60-100% with the four highest concentrations. Results indicate that ethazole possesses nematicidal activity at rates recommended for field application. Key Words: nontarget effects, terrazole, chemical control.
