1 Checking the Effectiveness of Pest Control Measures Chris Hayes, PhD (Tampa) SE Technical Sales Manager & Mexico Cell: /15/ Thanks Cultivate 15 Thanks to YOU, the Attendees! 6/15/ /15/ PREVENTION Biologicals Do Best When Applied Early DISEASED PLANTS?????? Apply after or with a Curative Chemical Start Clean Stay Clean COMPATIBLE?? 6/15/

2 RootShield Compatibility What is a Biological? Living: May Grow with Plant Immediate feeding Time to Establish Non-living Biologicals? Salts & Oils & Soaps Hammers for Quick Kill Plant Extracts Can Take Time to Control Need to be Ingested Activate Plant s Defense System 6/15/ APPROPRIATE BIOLOGICAL Attacks Proper Pest &/or Disease ENVIRONMENTAL DIVERSITY Suitable Habitat (temps, ph, moisture) COMPATIBILITY How Does The Biological Interact With Your Other Inputs (chemical & cultural) 6/15/ Living & Non-living Biologicals MECHANISMS OF BIOCONTROL Mycoparasitism (growth toward target fungi, lectinmediated attachment, cell wall degrading enzymes) Grow on Roots (Squatter s) Eat a Host Production of secondary metabolites Competitive Exclusion - competition for nutrients/space Tolerance to stress through enhanced root development Systemic Resistance Induced (ISR) or Acquired (SAR) Solubilization and sequestration of inorganic nutrients 6/15/ Conventional - IPM Sustainable - Organic Scout Set Action Thresholds Monitor and Identify Problem Prevention Control 6/15/ /15/

4 NemaShield & NemaShield HB Insect-Parasitic Nematodes Host: Fungus Gnat Larvae Steinernema feltiae, S. carpocapsae, S. scapterisci, Heterorhabditis bacteriophora Bacillus subtilis Squatter s Rights Rhizosphere Competency of Trichoderma harzianum, strain T22 (RootShield) Lipopeptides Disrupt Cell Membranes Cease Cell membrane Lipopeptide molecule Membrane phospholipids Image: Heiko Heerklotz, Univ. Basel Lipopeptides make membranes porous which allow other small molecules entry into pathogen cells 6/15/ /15/ Fungus Eating a Fungus Mycoparasitism Trichoderma harzianum, strain T22 Attacking a hyphal strand of Rhizoctonia using enzymes to degrade the cell wall of the pathogen 6/15/ RootShield Plus Eating Soil Pathogens Pythium (all) Phytophthora Rhizoctonia Fusarium Thielaviopsis Cylindrocladium Sclerotinia Sclerotium Myrothecium Others 6/15/

5 Biologicals can Grow With & On the Root BotaniGard WP & BotaniGard ES Beauveria bassiana (strain GHA) Wide spectrum of Activity: Whiteflies (including Psyllids Q-Biotype) Leafhoppers and plant Thrips (Foliage/Soil) hoppers Mealybugs (Foliage/Soil) Aphids Scarab beetles (White Grubs in Soil) Aphids Leaf-feeding beetles Weevils Chinch Bugs (in Soil) Ground Pearl 6/15/ /15/ EVALUATING CONTROL Loss of movement, coordination, and feeding of nymphs and adults (significant drop in 1 wk) Coloration change. Healthy Infected Fungi Eating Insects TANK MIXING Hammers with Residuals Biologicals w Chemicals Compatible Biologicals w Biologicals Compatible TIMING, TIMING, TIMING 6/15/ /15/ TANK MIX Cease Bacteria & Fungi MilStop Fungi (Bacteria & Insects) BotaniGard WP - Insects DO BIOLOGICALS WORK? YES, when Preventative, weeks to months Appropriate Biological Problem Site, low to moderate pressure Compatible (grows) with Your System Environmental Cultural Alive, shelf life 6/15/ /15/
