1 Pests and Diseases28.00: Examine distinguishing characteristics of pests so as to determine best management practices.29.00: Compare methods of control of horticulture plant pests.
2 What is an insect?Small animals that have three body regions and three pairs of legs equaling six legsBody regionsheadthoraxabdomen
3 Types of InsectsThe five types of mouthparts are important in identifying and controlling insects.ChewingPiercingRaspingSiphoningSponging
53 Disease ControlPreventing plant diseases is better than treating the diseasesPlant diseases must be identified before they can be treated
54 EnvironmentWarm temperatures and moist conditions in greenhouse plant production make most horticulture plant diseases worse because of environmental conditions that support disease-causing pathogens
55 Controlling InsectsInsects can be controlled using the following methods:biologicalchemicalculturalmechanicalnaturalquarantine
56 Biological ControlUses natural enemies such as birds, other insects, etc.
57 Chemical Control The use of pesticides or insecticides Insects must be killed when they are actively feeding or moving on the plant
58 Chemical Control Contact poisons Fumigants affect the insect’s nervous system and must come into contact with the insect to be effectiveFumigantspoisonous gases released into an enclosed place so that insects breathe the gases
59 Chemical Control Stomach poisons sprayed on the plant surfaces or are taken into the plant through absorption.The insect must suck the poison to get it into the stomach for this method to be effective.Systemic poisons are more effective for controlling sucking insects.
60 Cultural ControlInvolves sanitation, removing insect breeding and hiding areas and using insect resistant plant varieties
61 Mechanical ControlUses physical control such as insect traps, using screens over fans and other openings, and washing plants with soapy water.
62 Natural ControlMethods include natural barriers such as rivers, woods, mountains and predators to control insects.
63 QuarantinePhysically isolates insects from healthy plants
64 IPMA combination of control methods is called Integrated Pest Management or integrated control.
