Cultural Controls
These are management principles designed to reduce pest populations before outbreaks occur.
What are cultural practices?
Dead or unusable plants should be removed from the greenhouse for this reason.
What is to eliminate pest hosts?
This common herbicide is sprayed around greenhouse exteriors to suppress weeds.
What is glyphosate?
Keeping greenhouse rooms free of these helps reduce insect and pathogen harborage.
What are weeds?
This greenhouse condition should be reduced by adjusting plant spacing.
What is excess humidity?
This greenhouse practice limits the spread of insects and pathogens between crops.
What is avoiding unnecessary plant movement?
This type of chemical is commonly used to sanitize greenhouse surfaces.
What is bleach or disinfectant?
Recycled plastic containers should undergo this process before reuse.
What is sterilization?
Adjusting this production factor helps prevent overly moist conditions that encourage pathogens.
What is irrigation frequency?
Tracking these into the greenhouse increases contamination risk.
What are weed seeds and mud?
The removal of potential hosts is considered this type of pest management strategy.
What is prevention?
Cleaning benches, tools, and containers helps reduce this disease-causing group of organisms.
What are pathogens?
Proper crop spacing improves this critical greenhouse factor.
What is air circulation?
Overly dense plant spacing creates favorable conditions for this environmental issue.
What is high humidity?
IPM relies heavily on this management approach rather than reacting after outbreaks occur.
What is proactive management?
Changing irrigation methods can help suppress these moisture-loving greenhouse problems.
What are fungal diseases?
Removing plant debris primarily reduces populations of these two major threats.
What are insects and pathogens?
This type of contamination often enters greenhouses attached to shoes.
What is mud and seed weed contamination?
Avoiding movement of infected crops helps stop this process.
What is pest/pathogen spread?
The ultimate purpose of cultural controls is to make the greenhouse less this for pests.
What is hospitable?
This IPM principle emphasizes modifying the growing environment to discourage pest establishment.
What is environmental manipulation?
This practice is especially important when reusing pots between production cycles.
What is disinfecting/sterilizing recycled plastic?
Excessive irrigation often creates ideal conditions for this below-ground issue.
What is root disease?
Eliminating weeds removes these alternate resources for pest survival.
What are alternate hosts?
This overall pest strategy combines sanitation, spacing, irrigation, and exclusion practices.
What is integrated pest management (IPM)?
