MARYLAND PESTICIDE APPLICATOR TRAINING
EXAM | 2024 QUESTIONS AND ANSWERS
APPLICATION RATE - 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 - A UNIFORM SPRAY PATERN, EVEN SPACING
AND PROPER HEIGHT TO GIVE UNIFORM COVERAGE. UNIFORMITY IN
CONCENTRATION
SOIL INTERCEPTION - AN EVEN, UNIFORM SURFACE, FREE OF CLODS,
MANURE, PLANT LITTER AND OTHER DEBRIS WILL HELP ENSURE A GOOD
DISTRIBUTION PATTERN
INTERCEPTION BY LEAVES - THE ANGLE FORMED BETWEEN THE LEAF AND
STEM, DEGREE OF HAIRNESS, EXPANSION, AND RATIO OF LEAF AREA TO DRY
WEIGHT VARY.
RETENTION - 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 - RUNOFF CAN RESULT IF RAIN OCCURS DURING OR
SHORTLY AFTER APPLICATION. 1 TO 2 HOURS WITHOUT RAIN IS ENOUGH TIME
FOR PENETRATION.
PHYSICAL MOVEMENT - WIND AND WATER CAUSE RUNOFF OR MOVEMENT
FROM TRAGETED AREA. MOVEMENT IS TOWARD DEPRESSIONS, CAUSING
INCREASED CONCENTRATIONS
VOLATILITY - 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 - chemicals adhereing to foliage are broken down by
sunlight.
SOLUBILITY - THE ABILITY OF A CHEMICAL SUCH AS A PESTICIDE TO
DISSOLVE IN A SOLVENT, USUALLY WATER OR SOME OTHER LIQUID CARRIER
MOVEMENT IN SOIL - WATER TRANSPORT PROVIDES FOR THE GREATEST
AMOUNT OF HERBICIDE MOVEMENT IN THE SOIL.
