MARYLAND PESTICIDE APPLICATOR TRAINING UPDATED
QUESTIONS AND VERIFIED ANSWERS
APPLICATION RATE - CORRECT ANSWER✅✅✅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 - CORRECT ANSWER✅✅✅A UNIFORM SPRAY
PATERN, EVEN SPACING AND PROPER HEIGHT TO GIVE UNIFORM COVERAGE.
UNIFORMITY IN CONCENTRATION
SOIL INTERCEPTION - CORRECT ANSWER✅✅✅AN EVEN, UNIFORM SURFACE,
FREE OF CLODS, MANURE, PLANT LITTER AND OTHER DEBRIS WILL HELP
ENSURE A GOOD DISTRIBUTION PATTERN
INTERCEPTION BY LEAVES - CORRECT ANSWER✅✅✅THE ANGLE FORMED
BETWEEN THE LEAF AND STEM, DEGREE OF HAIRNESS, EXPANSION, AND RATIO
OF LEAF AREA TO DRY WEIGHT VARY.
RETENTION - CORRECT 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 - CORRECT ANSWER✅✅✅RUNOFF CAN RESULT IF
RAIN OCCURS DURING OR SHORTLY AFTER APPLICATION. 1 TO 2 HOURS
WITHOUT RAIN IS ENOUGH TIME FOR PENETRATION.
PHYSICAL MOVEMENT - CORRECT ANSWER✅✅✅WIND AND WATER CAUSE
RUNOFF OR MOVEMENT FROM TRAGETED AREA. MOVEMENT IS TOWARD
DEPRESSIONS, CAUSING INCREASED CONCENTRATIONS
VOLATILITY - CORRECT 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 - CORRECT ANSWER✅✅✅chemicals adhereing to foliage
are broken down by sunlight.
SOLUBILITY - CORRECT 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 - CORRECT ANSWER✅✅✅WATER TRANSPORT PROVIDES
FOR THE GREATEST AMOUNT OF HERBICIDE MOVEMENT IN THE SOIL.
FIELD CAPACITY - CORRECT ANSWER✅✅✅The amount of water remaining in the soil
after the soil is completely drained of gravitational water.
DEGRADATION - CORRECT ANSWER✅✅✅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 - CORRECT ANSWER✅✅✅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 - CORRECT ANSWER✅✅✅THE MOVEMENT OF A CHEMICAL INTO
PLANTS, ANIMALS MICROGANISMS, OR SOIL
TRANSLOCATION - CORRECT ANSWER✅✅✅THE MOVEMENT OF MATERIALS
WITHIN A PLANT OR ANIMAL FROM THE SITE OF ENTRY. A SYSTEMIC PESTICIDE
IS TRANSLOCATED
ACTIVATION AND DEACTIVATION - CORRECT ANSWER✅✅✅SOME
HERBICIDES ARE ACTVATED BY AN ENZYME SYSTEM AFTER ENTERING THE
PLANT, WHILE OTHERS ARE DEACTIVATED BY BEING BROKEN DOWN WITHIN
THE PLANT. THE RATE OR DEGREE OF DEGRADATION IS INFLUENCED BY
