Let’s take a closer look at1. MANAGEMENT2. CHEMICAL TECHNOLOGIES3. NATURAL TECHNOLOGIES
Management:
Plant Variety Reduced Inoculum Disease Monitoring Microclimate - water, temperature,
wind, … Management of Sub-Clinical Disease Other
Chemical Technologies: Fungicide Selection Dosage Timing Resistance
Natural Technologies:Bio-
Fungicides
Why integrate with Natural Technologies? Fungicide Resistance Withholding periods Effect chemical pesticides on:
–Growth suppression & Phytotoxciticy
–Soil health: Rhizophere damage
“A good integrated disease management
program will increase yield and quality!”
Managing subclinical disease?
Sub-Clinical Disease(Invisible)
Clinical Disease(Visible)
Time
Disease
Healthier plants More energy available
to the plant to use for growth
Better Yield and Quality!
Manage sub-clinical disease:
Categories of Bio-Fungicides
I. PredatorII. Competitive exclusionIII. AntibioticIV. ISR & SAR
Predator species Living micro-organisms
that kill plant pathogens
Competitive Exclusion
Beneficial living micro-organisms that compete with plant pathogens for the same resources.
Antibiotic
Natural substances that stop or slow the growth of microorganisms
Rhizoctonia
Control Procrop Shield
Pythium
Control Procrop Shield
Pytophthora
Control Procrop Shield
Sclerotinia

Sclerotium

Alternaria

Substances that induce the plant to defend itself using its own natural defence mechanisms.
Plants are primed prior to attack such that they are ready for pathogen attack
Systemic effect
SAR / ISR / Elicitors / Fortifiers

• Maximal 9 days after induction
• Lasts for ± 21 days• Need for continual applications

Typical Berry Crop Protection Program
Chemical Fungicide
Chemical Fungicide
Alternate Procrop ISR with ProCrop Shield Alternate with Regular pesticide program
Chemi. Fungi.
Same to lower price than “all chemical” program
Benefits: Withholding period Reduced use of chemicals – long term
performance Preventative program Resistance Post harvest quality
Cost of a Program that alternates Natural with Chemical?
