Why is understanding the nozzle flow rate essential in pesticide application?

Understanding the nozzle flow rate is crucial in pesticide application because it directly affects the amount of pesticide delivered per area. The flow rate determines how much pesticide is released through the nozzle over a specified period, which in turn impacts the efficacy of pest control treatments. When the flow rate is not appropriately set, uneven application can occur, potentially leading to areas being over-treated or under-treated. This can compromise the effectiveness of the pesticide and may result in unwanted consequences such as pesticide resistance, harm to beneficial organisms, or environmental contamination. Maintaining the correct flow rate ensures that the target areas receive the appropriate dosage of pesticide to effectively manage pest populations while minimizing potential risks to the environment and non-target organisms.
