Isn't 2,4-D used right in ponds? DO numbers should help. Hot day
Depends on the formulation, some formulations are toxic to fish, if I found the right label the one they sprayed is toxic to fish. A one - two punch, toxicity and a DO sag, and it may volatilize during hot weather.
In aerobic aquatic environments, the half life is 15 days, while in anaerobic aquatic environments,[clarification needed] 2,4-D was moderately persistent to persistent (half life of = 41 to 333 days). 2,4-D has been detected in streams and shallow groundwater at low concentrations, in both rural and urban areas. Breakdown is pH dependent.[30] Some ester forms are highly toxic to fish and other aquatic life.
Depends on type of 2-4-d used but esters fume under hot conditions and Crystalize in microscopic size and float in the air. 2-4-D can and will kill grass in this form.
I'm pretty sure the formulation used around my pond is the toxic to fish type, sales rep called it 2,4-D "6 lb.". Directly quoted from the PDF label I posted at the top of this page.

This pesticide may be toxic to fish and aquatic invertebrates. Do not apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high water mark. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas. Do not contaminate water when disposing of equipment wash waters or rinsate.

Do not apply at wind speeds greater than 15 mph. Only apply this product if the wind direction favors on-target deposition and there are not sensitive areas (including, but not limited to, residential areas, bodies of water, known habitat for nontarget species, nontarget crops) within 250 feet downwind. If applying a medium spray, leave one swath unsprayed at the downwind edge of the treated field

Oh my gosh! This makes me sick Shorty. So sad to see this. The guy that farms my fields works for the local fertilizer dealer. They do a lot of spraying. He sprayed this last Tuesday because he wanted to plant this week, and the weeds were already taking over. I haven’t been back up since. Supposed to get hard rains today and tonight.
I sure hope there’s some strong compensation for you, but you’ll still be starting over, I guess.
12 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs) I think that's about all I should put in my little pond. Otter attack in 2023.
Wow! Really sorry to hear about your fish kill. Some people just don't understand the feelings we have for our fish. I hope your neighbor is understanding and pony's up for a few grand.
Do not judge me by the politicians in my City, State or Federal Government.

So true Tracy....I rarely kill anything...when we find a cricket at our office I'll take it outside and let it go in the bushes...but if birds or otters start killing my fish...hey those fish are like our kids. It's WAR baby!
I too was unaware that different forms of 2,4-D affected fish differently, but have never used 2,4-D near water. I also read and follow labels on each product we buy.
70 SMB 6-7" (a total of 81 4-6" were stocked November 11th, 2018. Number includes two 17-1/2"+ SMB) 656 RES (4-5" average, some larger, some smaller) 151 GSH (5-9") 15 FHM 16 BF tadpoles. 1 Yellow Perch (10")
That's awful, Shorty. Really sorry that this happened.
After Pops retired from scratching dirt he spent about 15 years running spray rigs for MFA. He killed two ponds the first year he ran the spray rig. After that he refused to spray any field that had one if the wind was blowing.
I have been. The good news is the number of new floaters I am finding has slowed way down, bad news is the GB heron is working on cleaning up dead fish while I am at work today.
