temperature and humidity -Temperature: development is faster with heat &
affect insect development slower with cold temps; insects die at the high levels
of developmental threshold temps and become
inactive at low levels
-Humidity: effects insect diseases; effects moisture
levels required for survival
Advantages:
-Effective against economically damaging pests
-Can combine 1 or 2 insecticides to combat several
pests
-They act quickly to control pests before reaching
damaging levels
-For new pests, there are many compounds that have
Ch.1 List the advantages been proven effective
and disadvantages of -Effective insecticides, suitable formulations, &
using insecticides application equipment are normally available
Disadvantages:
-Often eliminate beneficial insects, allowing target
organisms to rebound quickly
-Repeated exposure can lead to resistance in a pest
population
-Yearly dependence on applications is an added cost
-Always a potential for drift, residues, and damage

-Interfere with management practices
-Produce chemical inhibitors that directly retard the
growth of desirable plants (allelopathy)
-Create a poor impression on customers
Ch.2 Describe ways that
-Interferes with pesticide applications
weeds can pose problems
-Support insect pests and plant diseases or provide
in turf and landscapes (7)
cover for rodents
-Are poisonous, allergenic, or irritating to people or
pets
-Dry out or die and become fire hazards
-Grasses (Monocots): most common weeds; have a
single seed leaf (cotyledon) when they germinate;
narrow leaves with parallel viens
Ch.2 Distinguish grasses
-Broadleaves (Dicots): have 2 seed leaves when they
from broadleaf plants and
germinate; veins form a net-like or branching pattern;
woody from herbaceous
can be broken down into Woody and Herbaceous
plants
plants
--> Woody: have thickened outer layer on stems (bark)
--> Herbaceous: lacks bark
-Annuals: live less than 12 months; most seeds
germinate the following year, some are dormant
taking several years; prolific seed producers.
--> Summer Annuals: germinate from seed in spring,
flower/produce seeds in summer, die in late
summer/early fall.
Ch. 2 Describe the life --> Winter Annuals: germinate from seed in fall,
cycles and propagation of overwinter as low-growing plants, flower/produce
annual, biennial, and seeds in spring, then die.
perennial plants -Biennials: live for 2 growing seasons; germinate from
seeds in spring or summer and produce a rosette of
leaves, overwinter in rosette stage, flower the
following year, produce seed, and die.
-Perennials: live for at least 2 years, sometimes longer;
may reproduce by seed or spread vegetatively
(stolons, rhizomes, spreading roots, tubers, bulbs)
