1. Optimising Biopesticides in Propagation
Ant Surrage

2. Biopesticide “One size does not fit all”
Technical Knowledge
IPM Programming, Pest & Disease Biology, MoA
Application
Equipment, mixing, calibration
Environment optimisation
Temperature, Humidity, VWC

3. Issues in Propagation Soft Growth Resistance
Biopesticides tend to be less harsh on soft growth
Resistance
Biopesticides tend to have multiple modes of action making them less likely to face resistance issues
Environmental & Biopesticides optimisation
The propagation environment tends to be conducive for optimum efficacy
New technology offers improved means to optimise biopesticides

4. Prestop - Gliocladium catenulatum
Action against
Pythium
Rhizoctonia
Fusarium
Botrytis spp
Acts as a hyperparasite producing enzymes which cause the breakdown of the cell walls of pathogens
Deprives pathogenic fungi of living space via competition at both the roots and aerial parts of the plant
Gliocladium Catenulatum (J1446)
Naturally occuring
Highly aggressive, soil-borne fungus
Survives on the rhizosphere and on aerial parts of plants for several weeks
(Icl-sf.com. (2019). Prestop - General Crops Prestop - General Crops ICL. [online] Available at:
Ref label restriction, wouldnt drench due to inhibition of roots

6. Serenade ASO - Bacillus Subtilis
Primarily for the control of Botrytis cinerea. However has a broad spectrum of activity.
Contact acting
Actively colonises roots
Systemic resistance to disease
Mutual relationship with root
Enhanced root structure
Improved nutrient mobilisation and uptake
(CropScience, B. (2018). Serenade ASO. [online] Bayer Crop Science UK. Available at:
For foliar use, the lipopeptides disrupt the cell membrane of the pathogen, resulting in physical breakdown. Soil application, actively colonises roots, forming a protective physical barrier against soil disease such as Pythium spp. Systemic resistance to diseases, priming plants to defend themselves against pathogens, activating the salicylic acid and gibberellic acid pathways. Mutual relation with the plant in the root zone. Enhanced root structure. Improved nutrient mobilisation and uptake

7. T34/Trianum- Trichoderma
Activity against
Fusarium oxysporum
Pythium
Phytophthora
Rhizoctonia
Sclerotinia
Multiple MoAs -
- Direct competition for space and nutrients
- Synthesis of biostatic compounds
- Hyperparasitism
- Inducing plant disease resistance mechanisms
