What Is Root Rot?
Root rot is one of the most serious threats to plants grown hydroponically and in water-retentive media. It occurs when roots are exposed to excessive moisture and poor oxygen levels, allowing bacteria, fungi, and mould to attack and break down root tissue.
Common symptoms include:
-
Wilting or stunted growth
-
Yellowing leaves
-
Black, brown, or mushy roots
-
Roots that break away easily when touched
Root rot is especially persistent in Deep Water Culture (DWC) systems, where inadequate aeration and oxygen deficiency accelerate the rotting process. If left untreated, root rot can quickly lead to plant death.
Why Choose Rot Stop?
-
Designed specifically for hydroponic and high-moisture environments
-
Long-lasting systemic protection
-
Easy-to-use liquid formulation
-
Proven control of root and stem diseases
-
Ideal for preventative and recovery treatments
Usage Rate & Application
Application Rate:
-
Mix 10ml per litre of water to create a drench
How to Apply:
-
Apply evenly to growing media to ensure full root zone saturation
-
Can be applied with nutrient solution
-
Allow treated media to sit for 4–6 hours before irrigating again
