Monitor Cotton Growth—First Open Boll to Preharvest

Arrangement of branches and fruiting positions on a cotton plant.

Plant monitoring (or mapping) provides a system to evaluate the growth and development of cotton plants throughout the season. You can use this information to fine tune management practices for the current crop stage. Many pest management decisions must be made at specific growth stages and plant mapping helps you time them precisely. Plant measurements and calculations for making management decisions change as the plant develops.

Plant monitoring from first open boll to preharvest focuses on measurements of:

Refer to the cotton anatomy diagrams to help identify these branches and nodes. For more information about making these measurements and for recording forms, ask your local farm advisor. You can also check the UCCE Cotton Production Information site for details on how to apply monitoring information for:

  • Plant growth regulator applications
  • Lygus treatments
  • Irrigation decisions
