Research

Understanding the relationship between soil inoculum density before planting and wilt development is essential for developing a disease risk assessment. In general, management options should be implemented at or before planting to prevent disease. Inoculum density can also be an important factor in determining the timing, nature, and duration of management practices. The objective of this study was to determine the effect of cotton cultivar selection on soil V. dahliae population over time, and its implications for Verticillium wilt development.
