Got White Mold?

Heads Up® is a valuable tool to help manage white mold. 

ISU Research has shown with Heads Up® you can expect

Lower overall incidence of disease
Fewer diseased plants
Reduction in the severity of white mold

What is White Mold?

  • White Mold or Sclerotinia Stem Rot is caused by Sclerotinia sclerotiorum
  • Over 400 host species of plants identified.
  • One of the major yield limiting diseases in soybeans and pulse crops
  • Fungus is present in stem or pods, known as sclerotia (look for hard, black resting bodies).  As part of the disease cycle these resting bodies overwinter in the soil. The following year, when the crop canopy closes during the reproductive growth stages, the sclerotia near the top of the soil germinate, producing air-borne ascospores that infect flowers, senescent petioles and leaves.
  • Favors cool and high moisture (wet) environmental conditions
  • Symptoms include white, bleached lesions on stems / white mycelium on surface of lesions ; followed by rapid wilting.  Can significantly reduce yield causing seed abortion / immature seed set.
  • Heads Up® is an excellent additional Mode of Action for White Mold prevention in both Soybeans and Dry Beans.
  • White Mold can be suppressed with many fungicides, but ONLY Heads Up® gives you preventative control from time of germination due to Systemic Acquired Resistance (S.A.R.)
8 leading White Mold Management Options:
  1. Field Tolerance. Select a variety that has exhibited good field tolerance / partial resistance to White Mold (Note: There are no completely resistant cultivars in most crops)
  2. Row Spacing. Wide rows help to allow air circulation which can reduces moisture captured in the canopy)
  3. Seed Population. Consider planting at a lower seeding rate.  By reducing the number of plants in a concentrated area you can partially manage the spread of mold.
  4. Weed Control. Manage weeds in crop, as several broadleaf weeds are also hosts to sclerotinia white mold.
  5. Rotation. Manage your rotation with non-host crops.
  6. Lodging. Avoid excessive fertilizer application to avoid lodging which  increases disease incidence
  7. Prevention. Treat your seed.   Heads Up® Plant Protectant is an EPA registered seed treatment which elicits your plants natural defenses to help genetically defend against white mold.
  8. Suppression. Research has shown in crop foliar fungicide during the flowering stage for soybean and pulse crops can be beneficial to suppressing white mold.
