it is volatile
Dream on getting the wind to be that still around here.... :lol: :lol: :lol: but yes, calm winds is best...droplet size another. Best quit spraying or lower pressure if you see the fine mist rising rather than falling....1wlimo":1zkh7m12 said:Sounds like the walking of 2-4-d is simular to Paraquat. To avoid this apply to a dry leaf in a light breeze (1 to 2mph) so there is rapid drying to the leaf.
If you apply it like glyphosate to a wet leaf, or when there is likley to be moisture rising from the ground as in early morning or after a light rain etc, this increases the risk of a problem.
That's where the volitility part comes in. The vapors of the stuff can kill plants just as quickly as the spray.MasseyFerg":f708kj81 said:2,4-d amine isn't as good as low vol ester. I have had it rain 30 minutes after spraying and the LV ester worked but the amine didn't
"I have heard that just opening a container of 2 4 D in a greenhouse where tomatoes are being sprouted/started that the tomatoes will perish." you heard wrong, you have to get it on hte plant to kill it. It's a growth hormone which makes the plant grow so fast that the cells just explode and plant dies. been around since the forties about as safe as any chemical out there.

Actually, you need the license to purchase more than a quart. I found this out when I bought some Amine at TSC - they said I could buy a bunch of quart bottles, but no gallon jugs.
