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?

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

Pytophthora

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

Same to lower price than “all chemical” program

Benefits: Withholding period Reduced use of chemicals – long term

performance Preventative program Resistance Post harvest quality
