Managing Spray Drift and Herbicide
Application Techniques 2025/2026 Exam
Questions and Answers | 100% Pass
Droplet Size - 🧠 ANSWER ✔✔Larger nozzles increase droplet size at same
output.
Drift Potential - 🧠 ANSWER ✔✔Minimize by selecting less volatile
pesticides.
Drift Managing Adjuvants - 🧠 ANSWER ✔✔Added to reduce spray drift risk.
Buffer Zone - 🧠 ANSWER ✔✔Distance protecting sensitive areas from
pesticide application.
,Sensitive Areas - 🧠 ANSWER ✔✔Habitats vulnerable to pesticide drift, e.g.,
water bodies.
Buffer Zone Distances - 🧠 ANSWER ✔✔Specified by pesticide labels for
sensitive areas.
Weather Conditions - 🧠 ANSWER ✔✔Affect buffer zone sizes, especially
wind speed.
Application Methods - 🧠 ANSWER ✔✔Different methods may require
varying buffer zones.
Sprayer Modifications - 🧠 ANSWER ✔✔Equipment changes can reduce
buffer zone requirements.
Record Retention - 🧠 ANSWER ✔✔Buffer zone summaries must be kept
for one year.
Temperature Inversions - 🧠 ANSWER ✔✔Lower ground temperatures can
increase drift potential.
Evaporation Effects - 🧠 ANSWER ✔✔High temperatures and low humidity
create smaller droplets.
, Wind Speed Impact - 🧠 ANSWER ✔✔Higher speeds increase droplet drift
risk.
Rainfast Period - 🧠 ANSWER ✔✔Time herbicide remains effective after
application.
Vapor Loss - 🧠 ANSWER ✔✔High surface temperatures cause loss of
volatile herbicides.
Spray Timing - 🧠 ANSWER ✔✔Avoid applications during temperature
inversions.
Wind Direction - 🧠 ANSWER ✔✔Affects drift; consistent direction is
preferable.
Anemometers - 🧠 ANSWER ✔✔Devices used to measure wind speed.
Portable Weather Stations - 🧠 ANSWER ✔✔Provide accurate wind speed
readings.
Herbicide Formulations - 🧠 ANSWER ✔✔Different types vary in volatility
and drift potential.
Drift Control Agents - 🧠 ANSWER ✔✔Change fluid viscosity, affecting spray
patterns.
