INTEGRATED PEST MANAGEMENT (IPM) IPM is an environmentally sound integration of all control methods to control pest populations below economic or damaging levels
IPM STRATEGIES u Prevention u Pest & Symptom Identification u Regular Survey for Pests (presence or symptoms) u Establish Action Thresholds & Guidelines
IPM METHODS u Cultural Control u Mechanical & Physical Control u Biological Control u Chemical Control
CULTURAL CONTROL u Growing healthy plants u Buying pest-free plant materials u Choosing resistant varieties u Choosing the planting site u Fertilization - too much or too little u Sanitation - removal of infected plant materials u Watering methods
MECHANICAL & PHYSICAL u Barriers - e.g., copper banding for snails/slugs u Mulching - for weed control & water conservation u Solarization - for control of weeds and diseases u Hosing & Syringing - for control of aphids, mites, & powdery mildew u Handpicking & Crushing - for many large insects and beetles u Hoeing - for weed control Trapping - e.g., pheromone traps for tobacco budworms
BIOLOGICAL CONTROL u Parasites (Parasitoids) - e.g., parasitic wasps & flies u Predators - e.g., lady beetles & lacewings u Diseases - e.g., milky spore for Japanese Beetle, beneficial nematodes, etc.
CHEMICAL CONTROL u Inorganic Pesticides - Derived from elemental sources: Sulfur u Organic Pesticides - Synthetic pesticides further classified by chemical families and modes of action. u Botanical Pesticides - Derived from plant materials: Pyrethrum, rotenone, rynia, bioneem, pepper oil, etc. u Microbial Pesticides - Derived from microbial organisms: Bacillus thuringienses
SIGNAL WORDS u POISON: Highly Toxic - Nicotine Sulfate u DANGER: Highly Toxic - Funginex (Triforine) WARNING: Moderately Toxic - Roundup u CAUTION: Slightly Toxic - many botanicals & microbial pesticides These words give information on the relative toxicity and corrosiveness of the pesticide
Cane Boring Insects Most cane boring insects are predaceous on other insects and use rose stems for nesting Predatory aphid wasp
Cynipid Gall Wasps – cause galls on leaves, stems & roots
Leafcutter Bees – d o not eat leaves; they use them for lining nests
Learn To Recognize The Good Bugs Of The Garden Leatherwinged Beetle Lady Beetle Larva Parasitized Aphid – A “Mummy” Lady Beetle Pupae Ground Beetle Scale Feeding Lady Beetle Larvae, Pupae & Adult Mealybug Destroyer Lady Beetle Larvae
The Squish Technique – works on other organisms
IPM IN THE HOME GARDEN u Establish damage levels for your own garden u Make observations and record them u Correctly identify the pest u Take the appropriate action; sometimes the appropriate action is no action
