What is the primary capacity required for a spray pump?

The primary capacity required for a spray pump is to be sufficient to supply all nozzles on the spray boom effectively. This means that the pump must be able to deliver the required flow rate and pressure to ensure uniform application of the pesticide across the entire spray width. Consistent and adequate pressure is essential for maintaining droplet size and coverage, which directly impacts the efficacy of the application. If a pump does not have the capacity to support all nozzles, it could lead to uneven spraying, which can result in inadequate pest control, potential crop damage, or environmental harm due to over-application in certain areas.

Additionally, this capacity ensures that the entire area being treated receives the proper dosage of the chemical being applied, enhancing both the effectiveness of the treatment and adherence to regulatory standards for safe application. In contrast, the focus on minimum capacity or emergency use does not account for the operational needs during regular spraying activities, which is why those alternatives would not satisfy the requirements for optimal pesticide application.
