Biological Defense Mechanism: How FitoDoctor Works

The FitoDoctor preparation is based on a specific strain of Bacillus subtilis bacteria. Unlike harsh chemical agents, this fungicide acts as a living shield. Once applied to the plant surface or root zone, the bacteria actively colonize the area, creating a competitive environment for phytopathogens. They produce natural antibiotics and enzymes that effectively dissolve the cell walls of fungal spores, suppressing the progression of Alternaria, Fusarium, and powdery mildew.

Dual-Action System: Contact and Systemic Properties

The core advantage of this formulation is the combination of two distinct types of activity:

• Contact Phase: The preparation forms a protective barrier, preventing spore germination on the leaf surface. This serves as your primary defense against bacteriosis and Septoria.
• Systemic Phase: The metabolites produced by Bacillus subtilis enter the plant's vascular system, boosting its innate immune response. This enables the control of root rots that are often inaccessible to standard contact fungicides.

Practical Application Details

The powder formulation ensures a long shelf life by maintaining the spores in a state of anabiosis. Activation occurs immediately upon mixing with water. Classified as a 4th-hazard class product, it is safe for humans, bees, and beneficial insects. This is critical for treating vegetable crops and tomatoes during the harvest period, when chemical pesticide usage is restricted or prohibited. It demonstrates high efficacy across various field crops (winter barley, cereals, potatoes) and cucumber crops, providing robust protection against late blight even under high-humidity conditions.
