A 10-port manifold was developed for the injection of insecticides into a drip irrigation system for small plot bell pepper research trials. A 179.1 metric ft lb/s positive displacement Aquaflow® electric chemical metering pump was used to transfer liquid chemical treatments from an 18.9 liter polyethylene bottle through a 10-valve manifold that allowed both water and up to 10 separate chemical treatments to mix and flow into the drip irrigation line of each treatment plot. Because very small

This system would be suitable for chemigation research trials in most row crop trials using drip irrigation with or without plastic mulch.
