MARYLAND PESTICIDE APPLICATOR
TRAINING EXAM QUESTIONS AND
ANSWERS. VERIFIED 2025/2026.
APPLICATION RATE - ANS THE AMOUNT OF PESTICIDE THAT IS APPLIED TO A KNOWN AREA,
SUCH AS AN ACRE OR 1,000 SQUARE FEET OR LINEAR FEET
UNIFORMITY OF DISTRIBUTION - ANS A UNIFORM SPRAY PATERN, EVEN SPACING AND
PROPER HEIGHT TO GIVE UNIFORM COVERAGE. UNIFORMITY IN CONCENTRATION
SOIL INTERCEPTION - ANS AN EVEN, UNIFORM SURFACE, FREE OF CLODS, MANURE, PLANT
LITTER AND OTHER DEBRIS WILL HELP ENSURE A GOOD DISTRIBUTION PATTERN
INTERCEPTION BY LEAVES - ANS THE ANGLE FORMED BETWEEN THE LEAF AND STEM,
DEGREE OF HAIRNESS, EXPANSION, AND RATIO OF LEAF AREA TO DRY WEIGHT VARY.
RETENTION - ANS KEEPING SPRAY DROPLETS ON THE LEAF IS AN IMPORTANT
CONSIDERATION ONCE CONTACT WITH TH LEAF HAS BEEN MADE. THE TYPE OF LEAF SURFACE
WILL EFFECT RETENTION
WEATHER CONDITIONS - ANS RUNOFF CAN RESULT IF RAIN OCCURS DURING OR SHORTLY
AFTER APPLICATION. 1 TO 2 HOURS WITHOUT RAIN IS ENOUGH TIME FOR PENETRATION.

, PHYSICAL MOVEMENT - ANS WIND AND WATER CAUSE RUNOFF OR MOVEMENT FROM
TRAGETED AREA. MOVEMENT IS TOWARD DEPRESSIONS, CAUSING INCREASED
CONCENTRATIONS
VOLATILITY - ANS A measure of how quickly a material passes into the vapor or gas state; the
greater the volatility, the greater its rate of evaporation
PHOTODECOMPOSITION - ANS chemicals adhereing to foliage are broken down by sunlight.
SOLUBILITY - ANS THE ABILITY OF A CHEMICAL SUCH AS A PESTICIDE TO DISSOLVE IN A
SOLVENT, USUALLY WATER OR SOME OTHER LIQUID CARRIER
MOVEMENT IN SOIL - ANS WATER TRANSPORT PROVIDES FOR THE GREATEST AMOUNT OF
HERBICIDE MOVEMENT IN THE SOIL.
FIELD CAPACITY - ANS The amount of water remaining in the soil after the soil is completely
drained of gravitational water.
DEGRADATION - ANS THE PROCESS BY WHICH A CHEMICAL COMPOUND IS BROKEN DOWN
TO A SIMPLER COMPOUND BY THE ACTION OF MICROORGANISMS, WATER, AIR, SUNLIGHT, OR
OTHER AGENTS
ADSORPTION - ANS THE PROCESS WHERBY CHEMICALS ARE HELD OR BOUND TO A SURFACE
BY PHYSICAL OR CHEMICAL ATTRACTION. CLAY AND HIGH -ORGANIC SOILS TEND TO ABSORB
PESTICIDES
ABSORPTION - ANS THE MOVEMENT OF A CHEMICAL INTO PLANTS, ANIMALS
MICROGANISMS, OR SOIL
