RIGHT-OF-WAY PESTICIDE EXAM
QUESTIONS WITH VERIFIED OUTLINED
ANSWERS
\.Root-absorbed herbicides are more effective when applied
postemergence. T or F - ANSWERS✔-False
\.Define contact herbicide - ANSWERS✔-kills where it directly contacts.
Controls annual and biennial
\.Define systemic herbicide - ANSWERS✔-used for perennial weeds.
Moves throughout the plant
\.Temperature, moisture, soil-type and rate of application influence the
persistence of a herbicide. T or F - ANSWERS✔-True
\.What is temperature inversion and how can it affect pesticide drift? -
ANSWERS✔-Temp inversion is when ground air is 2-5 deg cooler than
air above it. It increases drift deposits
, \.What is the difference between a selective and non-selective herbicide
- ANSWERS✔-selective doesn't kill surround veg. non-selective removes
most veg
\.If a plant's growing points are below the soil surface, which type of
herbicide will provide better control: contact or systemic? - ANSWERS✔-
systemic
\.How can leaf shape affect herbicidal action - ANSWERS✔-herbicides
will runoff narrow and upright leaves. Broad leaves hold herbicide
longer
\.What climatic factors affect herbicides - ANSWERS✔-humidity, light,
precipitation, wind, temp, length of growing season
\.what are the five categories of selective herbicide applications -
ANSWERS✔-foliage spraying, basal spraying, granular/pellet,
spotgun/exact dose, cut surface herbicide
\.What are the 3 basic foliage spray treatments used in right-of-ways. -
ANSWERS✔-low volume ground foliage, high ground foliage, aerial
