How to Manage Pests
UC Pest Management Guidelines
Baldhead is a condition that occurs when seedlings are severely stunted and have little or no growth above the primary (first) leaves as a result of death or damage of the growing point.
Baldhead is due to physical damage to the seed, which may occur during harvesting, threshing, cleaning, handling, or planting operations. Seed with low moisture content is most susceptible to such damage.
Exercise care during harvest, storage, and planting of bean seed. Moisture content of seed should be maintained around 14 to 15%.
