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

Page 9: Integrated Disease Management: For Fashion or Profit?

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

Page 12: Integrated Disease Management: For Fashion or Profit?

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

Page 14: Integrated Disease Management: For Fashion or Profit?

Predator species Living micro-organisms

that kill plant pathogens

Page 15: Integrated Disease Management: For Fashion or Profit?

Competitive Exclusion

Beneficial living micro-organisms that compete with plant pathogens for the same resources.

Page 16: Integrated Disease Management: For Fashion or Profit?

Antibiotic

Natural substances that stop or slow the growth of microorganisms

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

DAYS

• Maximal 9 days after induction

• Lasts for ± 21 days• Need for continual applications

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?
