| I heard the other day that the temperature has to be a certain degrees or hotter for 24D to work,does anybody know what temperature? He wasn't for sure but said that it has to be warm. Thanks |

Southeast South Dakota | the 24d label say to apply while the weeds are actively growing....... |

| Ester formulation works better in cool temperatures. Amine works better as the temperature warms up. My guess is somewhere between 70 and 80 degrees would be a good place to do the switch. Have gotten a weed kill in 50 degree temps with 2-4d Ester. |

Iowa | Has to be 50 the day you spray it. A sunny 50 is better. You can spray it before it gets to 50 also, as long as it gets to 50 later that day. |

Kentucky | I think the key is that the weeds are actively growing which generally means highs above 50 and lows above freezing. The ester will work well cool or hot. The problem with the ester and warmer temps is with the volatility of the ester and the product getting up and moving after you spray if it hasn't been rained into the soil. This of course results in your unhappy neighbors calling because their rose bush's leaves are cupped.
It WILL work in some very cool weather if the weeds have been growing. It just won't work nearly as fast much like glyphosate in that regard, but I think the same can be said for most products. |

| using 2-4d- ester for round-up soybeans our seedman wants us to wait at least 10 days to no-till beans. How many days does everybody else wait in between spraying 2-4d- ester and planting soybeans |

At least 10 days wait -- 14 is better. The quicker you get a rain after application, the longer you should wait. Delayed rainfall will result in more volatility loss which means there is less to move into the soil. I think the label says to wait 30 days if you use as much as 1 quart per acre. The 10-14 days is at the 1 pint rate. If you plant too soon, you may still get a good stand, but the beans won't grow off right. Dig them up and you will find that the 2,4-D has stunted the root system. Don't ask me how I know, but I will tell you that I planted 7 days after a 2,4-D/Scepter combo once. |

| Thanks Jmark, seed man said between 10- to 14 days. Hopefully we can get the fields sprayed in early April, usually try to start no-tilling beans around April 20 here in West Central Ohio. |

It does have soil activity and maybe the weeds were growing. The label usually describes optimum conditions. |
