QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS 100%
CORRECT RATED A+
What is a Restricted Use Pesticide (RUP)?
✔✔ These are pesticides that can only be used by individuals who are certified
applicators, authorized by the Iowa Department of Agriculture and Land
Stewardship (IDALS).
What categories of pesticide applicators exist in Iowa?
✔✔ The different classifications include: Commercial, Public, Noncommercial,
Private, and Certified Handlers (note: handlers are certified but not licensed as
applicators).
How can an applicator renew their certification in Iowa?
✔✔ 1) By passing the required exams again every three years.
✔✔ 2) By attending state-approved Continuing Instruction Courses (CICs) for
each certification category held annually.
Plant Disease - ANSWER✔✔Any abnormal condition that damages a plant and
alters its appearance
Plant Disease Triangle - ANSWER✔✔Susceptible host plant, a pathogen, and a
favorable environment
Symptoms - ANSWER✔✔Visible effects of plant disease
, Temperature and Moisture (Air and Soil) - ANSWER✔✔The most important
environmental factors
Relative humidity, Soil pH, soil texture, light, nutrient status, compaction, tillage
practices, planting depth, seed bed preparation, and residue management -
ANSWER✔✔May affect disease development
Major groups of plant pathogens - ANSWER✔✔Fungi, bacteria, viruses,
nematodes, non- infectious disorders
Fungi - ANSWER✔✔Largest group, lack chlorophyll, obtain food from decaying
organic matter/living tissue, has hyphae (fuzzy stuff) to absorb moisture and
nutrients, reproduce with spores that can survive in soil and decaying plant
material for a long time, some produce sclerotia to store nutrients to help them
survive, leaf spots, blights, root rots, seedling blights, wilts, stalk rots
Bacteria - ANSWER✔✔.
Extremely small microorganisms, reproduce by simple division, split into two
approximately equal halves that turn into fully developed bacterium, can reproduce
very quickly, clump together in colonies, obtain food from living and dead tissue,
in the absence of a host they decline quickly, leaf spots, water soaking of tissue,
soft rots of tissues
Viruses - ANSWER✔✔Infectious, disease producing particles, noncomplete living
systems, complex chemical molecules, genetic material surrounded by a protein
coat, induce host cells to form more viruses, transmitted my insects machines and
people when they take infected sap with them to a healthy plant, mosaic patterns
on leaves, deformation of plant tissues, stunting, reduced yield
