MARYLAND PESTICIDE APPLICATOR
CERTIFICATION TEST PAPER 2026 COMPLETE
SOLUTIONS GRADED A+
◉ UNIFORMITY OF DISTRIBUTION. Answer: A UNIFORM SPRAY
PATERN, EVEN SPACING AND PROPER HEIGHT TO GIVE
UNIFORM COVERAGE. UNIFORMITY IN CONCENTRATION
◉ SOIL INTERCEPTION. Answer: AN EVEN, UNIFORM SURFACE,
FREE OF CLODS, MANURE, PLANT LITTER AND OTHER
DEBRIS WILL HELP ENSURE A GOOD DISTRIBUTION PATTERN
◉ INTERCEPTION BY LEAVES. Answer: THE ANGLE FORMED
BETWEEN THE LEAF AND STEM, DEGREE OF HAIRNESS,
EXPANSION, AND RATIO OF LEAF AREA TO DRY WEIGHT
VARY.
◉ RETENTION. Answer: 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. Answer: RUNOFF CAN RESULT IF

, TO 2 HOURS WITHOUT RAIN IS ENOUGH TIME FOR
PENETRATION.
◉ PHYSICAL MOVEMENT. Answer: WIND AND WATER CAUSE
RUNOFF OR MOVEMENT FROM TRAGETED AREA.
MOVEMENT IS TOWARD DEPRESSIONS, CAUSING INCREASED
CONCENTRATIONS
◉ VOLATILITY. Answer: 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. Answer: chemicals adhereing to foliage
are broken down by sunlight.
◉ SOLUBILITY. Answer: THE ABILITY OF A CHEMICAL SUCH AS
A PESTICIDE TO DISSOLVE IN A SOLVENT, USUALLY WATER
OR SOME OTHER LIQUID CARRIER
◉ MOVEMENT IN SOIL. Answer: WATER TRANSPORT PROVIDES
FOR THE GREATEST AMOUNT OF HERBICIDE MOVEMENT IN
THE SOIL.
◉ FIELD CAPACITY. Answer: The amount of water remaining in the
