Biological Control of Damping-Off Diseases with Seed Treatments

Part of the NATO ASI Series book series (NSSA, volume 230)


The treatment of seeds with antagonistic bacteria and fungi has been used successfully to protect the germinating embryo and seedling against soilborne damping-off pathogens such as Pythium spp. (Hadar et al., 1984; Lutchmeah and Cooke, 1985; Howell and Stipanovic, 1980) and Rhizoctonia solani (Howell, 1982; Howell and Stipanovic, 1979). Application of bio-control agents to the seed effectively controlled disease not only in greenhouse environments, but also in the field. Crops protected under field conditions include sweet corn, wheat, peas, beans, and chickpeas (Harman and Taylor, 1990; Harman et al., 1989; Trapero-Casas et al., 1990; Callan et al., 1990). Some of these biocontrol agents are in the final stages of large-scale production, field testing, and registration (Harman and Taylor 1990). A seed-inoculant product composed of Bacillus subtilis (Quantum 4000TM) is commercially available in the United States (Connick et al., 1990).
