chemical
Define pesticide Any material used to kill, attract, repel, regulate, or
interrupt growth and mating of pests, or to
regulate plant growth
Contact pesticides Must physically touch the pest organism or be
sprayed on the site the pest frequents to exert an
action
Example would be protective fungicide
Must be re-applied to new plant tissues or if
precipitation washes product off
Systemic pesticide Enters the plant via roots or above ground plant
tissues and is moved inside of the plant.
Could render plant toxic to insect or mice
Could move through plant to kill parts of the plant
Example would be curative fungicide because it

Postemergence Applied to actively growing plants.
Work best in sunlight, high humidity, good soil
moisture
Selective pesticide Control only certain types or stages of pests while
leaving nontarget organisms unaffected.
Example would be herbicide that kills broadleaf
weeds and not turfgrass
Nonselective pesticide Exert their action on a wide variety of pests.
Control most of the plants they are sprayed on.
Identify the best application timing Plant diseases
for effective pest control as it For fungicides, it is critical that susceptible tissues
pertains to: plant diseases, insects, be protected before an infection begins or at the
and weeds first appearance of any symptoms
Insects
The younger the stage of insect, the more
susceptible it is to chemical control.
Weeds
Generally most effective when applied to actively
growing plants and least effective when plants are
not actively growing
Annual weeds are easiest to control in early spring
Biennials should be treated in fall or early spring
when in the rosette stage
Perennial weeds can be controlled in early bloom
stage or in the fall
