NYSDEC PESTICIDE APPLICATORS
EXAMINATION TEST 2026 QUESTIONS WITH
ANSWERS GRADED A+
◉ - Temperature fluctuation from HVAC
- Low humidity
- Dust
- Low light or high variation in light exposure
- Drafts
- Exposure to spills or cleaning compounds. Answer: Name 4 stress
factors that can harm plants growing indoors
◉ Light, air, moisture, and nutrients. Answer: What are the basic needs
of plants?
◉ - Temperature
- light
- relative humidity
- soil moisture
- availability of essential minerals. Answer: Name 4 environmental
factors that effect plant growth
,◉ - Lack of root space
- Lack of rainfall
- Insufficient irrigation. Answer: What abiotic factors may lead to
drought stress?
◉ 55-90 degrees. Answer: What is the ideal temperature range for
indoor plants?
◉ Low temperatures slow growth and chilling injuries. High
temperatures result in wilting and use of food stores. Temperature
fluctuations cause shock.. Answer: What do drastic temperatures do to
plants?
◉ Measures of accumulated heat. Degree days help predict the
development timelines of insects, weeds, or diseases.. Answer: What are
degree days?
◉ More light = more growth
More growth = more water required. Answer: What is the relationship
between how much light a plant receives and the amount of water that it
needs?
◉ Wilting, decreased food production, browning of leaf margins,
scorched leaves, and dull foliage. Answer: What negatives are caused by
low humidity?
, ◉ To allow roots to take in oxygen and give off carbon dioxide. Answer:
Why do plants need pore spaces in growing media?
◉ Macronutrients are chemical elements that plants need in relatively
large amounts. Micronutrients are elements needed in smaller amounts.
Both are necessary for good nutrition and health. Answer: What is the
difference between macro- and micronutrients?
◉ To supplement mineral nutrients needed for growth. Answer: Why do
plants need fertilizers?
◉ - Crust of fertilizer on the surface of the soil
- Yellowing/wilting leaves
- Browing of leaf tips/margins
- Leaf spot
- Browned/blackened/limp roots
- Leaf drop
- Very slow growth or little growth
- Death of plant tissue. Answer: What are the signs of overfertilization?
◉ Moisture, support, nutrients, and aeration. Answer: What vital
elements should a plant's growing medium provide?
