IPM (Integrated Pest Management) - IPM is a holistic approach to pest control that
combines biological, cultural, mechanical, and chemical control methods in a sustainable way. It
aims to minimize the use of harmful chemicals while effectively managing pests.
Weed Life Cycles - Weeds are classified based on their life cycle and how they grow and
reproduce. The three main life cycle categories for weeds are annuals, biennials, and perennials.
Annuals - Complete their life cycle (germination to seed production) in one growing
season. Examples: crabgrass, pigweed.
Biennials - Live for two years. They grow in the first year and flower/seed in the second.
Example: wild carrot.
Perennials - Live for more than two years, often regrowing from roots or rhizomes.
Examples: dandelion, clover.
Weeds as Indicators of Adverse Soil Conditions - Certain types of weeds can indicate
underlying soil issues, such as nutrient imbalances, pH problems, or poor soil structure.
Excessive Nitrogen - Weeds like lambsquarters or chickweed.
Acidic Soil (Low pH) - Weeds like moss or clover.
Compacted Soil or Poor Drainage - Weeds like dandelion or plantain.
Contact Herbicides - Contact herbicides kill only the parts of the plant that they directly
touch. They typically do not affect the roots.
Translocated Herbicides - Translocated herbicides are absorbed by the plant and then
moved (translocated) throughout the plant, killing it by targeting the roots and other plant
systems.
Preemergence Application - Preemergence herbicides are applied before weed seeds
germinate. These herbicides target the seedling growth stage.
Postemergence Application - Postemergence herbicides are applied after weeds have
emerged from the soil.
, Herbicide Modes of Action - Herbicide modes of action refer to how herbicides affect
plants at a biochemical level, often targeting specific processes in plant growth.
Surface Feeding Insects - Surface feeding insects feed on plant parts above the soil,
typically leaves, stems, and flowers.
Subsurface Feeding Insects - Subsurface feeding insects feed on plant roots or
underground parts, often causing damage to the plant's ability to absorb water and nutrients.
Root Pests - Includes pests like root maggots, rootworms, and certain beetle larvae.
Often harder to detect than surface feeders, as they are hidden underground.
Insecticide - An insecticide is a chemical substance used to control or kill insects.
Systemic Insecticide - Can be absorbed by the plant.
Contact Insecticide - Affects only insects that come into direct contact.
Broad-spectrum Insecticide - Affects many insect species.
Selective Insecticide - Affects only specific pests.
Examples of Insecticides - Pyrethroids, neonicotinoids, organophosphates.
Disease Triangle - The Disease Triangle is a concept used to explain the three necessary
components for plant disease to occur: the host (plant), the pathogen (disease-causing
organism), and the environment (favorable conditions for the pathogen).
Host - A susceptible plant.
Pathogen - A disease-causing organism (e.g., fungi, bacteria, viruses).
Environment (in Disease Triangle) - Conditions like temperature, moisture, and soil health
that favor disease development.
Pathogen (definition) - A pathogen is any organism that causes disease in its host.
Types of Pathogens - Pathogens can be bacteria, fungi, viruses, or nematodes.
IPM (Integrated Pest Management) - IPM is a sustainable approach to managing pests
that combines different control methods (biological, cultural, mechanical, and chemical) in a
way that minimizes harm to the environment, humans, and non-target organisms.
Monitoring (in IPM) - Regular inspection of crops to detect pests early.
