Principles and Methods of Plant Pest Control Flashcards
The prime requisite when managing plant pest is that it must be _______.
The prime requisite when managing plant pest is that it must be economical.
The aim of managing plant disease is for the total absence of the pest.
True or False
False.
The aim of managing plant disease is to prevent an intolerable build-up of disease within a plant population, not for a total absence of pest.
The purpose of managing plant diseases is to increase disease development, maintain tolerable disease incidence, and maximize yield loss.
True or False
False.
The purpose of managing plant diseases is to prevent disease development, maintain tolerable disease incidence, and minimize yield loss.
Passport for your plant.
Phytosanitary Certificate
Controls aimed at Suscept
- Protection
- Immunization
Controls aimed at Pathogen
- Exclusion
- Eradication
To prevent the import and spread of plant pathogens into areas from which they are absent.
Avoidance / Exclusion
To ensure that the susceptible host and favorable environmental conditions for the pathogen do not coincide.
Avoidance / Exclusion
It is the use of pathogen-free propagating plant material
Avoidance / Exclusion
Regulations controlling the import and export of plants to prevent the spread of disease and pests.
Quarantine and Inspection
Each state is responsible for enforcing quarantine regulations to prevent the spread of pest and disease within the state.
True or False
True
Inspection of plant / insects at legal entry checkpoints
Quarantine and Inspection
All planting materials, plant products, insects, etc. prohibited materials subjected to inspection at the entry checkpoint and found infested or infected shall be treated, quarantined, or destroyed.
True or False
True
This document certifies that the plants are free from harmful pests and diseases.
Phytosanitary Certificate
It ensures that a plant can safely enter the country without posing a threat to local agriculture.
Phytosanitary Certificate
Phytosanitary permits are issued by the __________.
National Plant Protection Organization (NPPO)
What does NPPO stand for?
National Plant Protection Organization
This is the government agency responsible for plant health in the country of origin.
National Plant Protection Organization
Phytosanitary permits typically includes details about the type of plant, quantity, country of origin, and any treatments or inspections performed.
True or False
True
Phytosanitary permits are required at ports of entry.
True or False
True
Depending on the country and plant type, additional documents such as import licenses or health certificates are not needed.
True or False
False
Depending on the country and plant type, you might also need other documents such as import licenses or health certificates.
This principle aims to reduce or eliminate the amount of pathogen after it is introduced into an area but before it has become well-established or widely spread.
Eradication Principles
The Eradication principle can be applied to:
________
________
________
- Individual plants
- Seed lots
- Fields or regions
The Eradication principle is generally not effective over large geographic areas.
True or False
true
(5) Eradication can be done by….
- Destroying weeds that are reservoirs of various pathogens or insect vectors of disease
- Biological control of plant pathogen
- Crop rotation
- Soil treatment
- Heat and Chemical treatment
Eradication can be done by burning of infected crop residue
true or false
True
It is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons.
Crop Rotation
It seeks to balance the fertility demands of soil nutrients.
Crop rotation
The principle regarding preventing infection by creating a chemical toxic barrier between the plant surface and pathogens.
Protection
It protects the plant directly from any infections that are likely to arrive.
Protection
Protection can be done by: (4)
- Modification of the environment (covered with plastic sleeves) (raised planting beds)
- Modification of the host nutrition
- Chemical control of insect vector
- Chemical treatment
The most important and effective principle of achieving successful management of plant disease.
Immunization / Resistant
It prevents infection or reducing the effect of infection by managing the host through improvement of resistance in it by genetic manipulation.
Immunization
Plant breeders either search for or developed suck resistant varieties of plants in which the host defends itself against the pathogen.
True or False
True
