To manage head blights and molds, sorghum growers should rotate crops and do which of the following?

To effectively manage head blights and molds in sorghum, one of the most effective strategies is to plant adapted, tolerant hybrids. These hybrids have been specifically developed or selected for their ability to withstand specific stresses, such as diseases and weather conditions that promote blight and mold development. They often possess genetic traits that enhance their resistance to pathogens, ensuring better yields and less reliance on chemical treatments.

By integrating the use of resistant or tolerant hybrids into crop management practices, growers can significantly reduce the risk of disease outbreaks. This proactive approach not only contributes to healthier crops but also aids in maintaining sustainable agricultural practices. In the context of managing head blights and molds, this method is crucial as it helps to break the disease cycle and lower the pathogen load in the soil or crop environment.

In contrast, ignoring crop residues could potentially leave disease spores and pathogens in the field, which may lead to increased problems in subsequent crops. Extending harvest times could expose sorghum to more environmental conditions conducive to mold development. Increasing chemical applications might manage the symptoms but won't address the underlying issues such as crop resilience and could also lead to concerns about chemical resistance and environmental impact. Thus, planting adapted, tolerant hybrids represents a fundamental and forward-thinking approach to managing these prevalent issues
