TruGreen General Pest Management 7A Practice Test

The point at which a spray starts to run or drip is crucial in pest application because it signifies the threshold beyond which the pesticide will no longer adhere to the target surface. This is important for ensuring that the pesticide is applied effectively and in sufficient quantities to manage pest populations. If application exceeds this point of runoff, the efficacy of the pesticide is likely compromised, as it may lead to uneven distribution, wastage, or environmental contamination. Understanding this point helps in calibrating equipment and determining application rates to maximize pest control while minimizing negative impacts. Techniques like monitoring droplet size and maintaining appropriate pressure during application also contribute to staying within this critical limit.
