Pest Management Flashcards
Integrated pest management (IPM)
solving pest issues while minimizing human risk
Most important step of IPM
Monitoring to know exact time to start and what your problem is
5 components of IPM programs
Prevention
Identification
Monitoring and assessing numbers and damage
Guidelines for when action is needed
Combination of biological, cultural, physical/mechanical and chemical tools
Physical Damage that can kill insects
tillage
Plant competition advantages
enhanced with proper fertility
limits room weeds have
ability varies by crop
three classes of pesticides
herbicides, fungicides, insecticides
Rotation reasons
some crops compete better
specific herbicides work better
Biological control
using natural predators
insects and disease
Advantages and disadvantages of biological control
ad- selectivity, inaccessible areas, less environmental impact
dis- few options, slower
key factor in gaining control of weeds
many methods
Biological disease control options
choosing resistant crops
starting with clean seed
providing good growing conditions
Cultural practices to avoid disease
early seeding
crop rotation
removal of diseased residue
cleaning machinery
How do plant varieties have resistance to insects
producing a substance to hurt the insect
having a trait to make themselves undesirable
Beauveria bassiana
fungus used to control arthropods by breaking down insect body and then using it as food
Bacillus thuringiensis (Bt)
naturally occurring soil bacteria that produces a protein that is poisonous to insects. potatoes can have this in their leaves to prevent being eaten
