Botrytis (Bud Rot): Prevention, Identification & Treatment
Botrytis cinerea, commonly known as bud rot, is a devastating fungal disease that can quickly destroy cannabis flowers, leading to significant yield loss. It thrives in humid, poorly ventilated environments, attacking dense buds and spreading rapidly. This section focuses on early detection, prevention, and effective treatment strategies to safeguard your crop.
Signs & Symptoms of Botrytis:
Early Stage: Soft, darkened spots on buds and leaves
Progression: Grayish-white mold developing inside dense flowers
Advanced Stage: Buds become brown, mushy, and crumble to the touch
Spread: Spores spread through air, water, and plant-to-plant contact
Prevention & Control Measures:
Humidity Control: Keep RH below 50% during flowering to prevent fungal growth
Airflow & Ventilation: Increase air circulation to reduce moisture buildup
Defoliation & Spacing: Remove excess foliage to allow light and airflow penetration
Fungicidal Treatments: Organic solutions like neem oil, potassium bicarbonate, and beneficial microbes
Quick Removal: Immediately discard infected buds to prevent further spread
