The continuous mechanical mixing of a pesticide via an agitator within the spray tank to prevent phase separation is designated_________________?
Show answer Hide answer
Answer: D. Agitation
Explanation
Agitation keeps pesticide particles evenly suspended within liquid spray tank mixtures continuously. Mechanical paddles or hydraulic bypass systems prevent heavier active ingredients from settling downward. Without constant agitation, spray applications deliver inconsistent concentrations across treated fields. Wettable powders and suspension concentrates tend to separate rapidly in water-filled tanks. Proper agitation ensures uniform chemical distribution throughout the entire liquid application process. Tank pumps or mechanical stirring rods provide the necessary kinetic energy for mixing.
Inconsistent tank mixing leads to crop damage from overly concentrated chemical hot spots. Operators must maintain proper agitation from initial mixing until the final spray completes. Equipment calibration checks always verify that internal tank agitators function correctly. An activator enhances the intrinsic phytotoxic activity of a primary pesticide compound. Synergism occurs when two chemicals combine to produce toxicity greater than individual sums. An adjuvant is a formulation additive that improves overall spray application physical properties.
