DuPont's Imprelis may not have direct toxicity to fish, but the excessive fallout from needle drop and other plant debris caused by Imprelis damage near a person's water feature can be a problem. I've got a tight net now covering my koi pond, instead of the larger spaced net, but it does make feeding a little more difficult. I feel bad for Cindy who already lost one of her koi, which came from Japan, possibly due to the large needle fall from the Imprelis damaged tree last year before much was known about this Imprelis disaster. The indirect effect on birds, insects and invertebrates from Imprelis damaged plants is something that needs studied, as some of us are witnessing these eco system alterations and damages.
