Spray herbicide in cold

Can you spray herbicides such as a 3-way mixture in when the weather is still cold? And will it be effective?
These weeds were sprayed at a temp average of about 40 degrees on March 28.

And then at a temperature only slightly warmer of average for the day of 46 on April 7, 2013 .
Weeds were yellow rocket.
Both sprays appeared to work, or at least to result in major distortion and yellowing...so far.

Good luck. Killing half baked weeds is a biotch. Your mode of action is all messed up to start with.

If it hasn't gotten too warm yet (not sure where you are located) I would go with a product called Super Trimec. A gallon will cover up to 4 acres so it has become a very cheap application for me. I was on a site called www.lawnandpestcontrolsupply.com earlier this week and saw some for under $90 which is what you will pay in a local store if they even had it. I have bought insecticides from though so you can trust that site. Be careful though because the product gets hot fast once your up in the 80s.

You can use regular Trimec (3 way) with not much problems in cold, its the mix rate which will matter most, especially being that this post was originated in Apr. - transition spraying comes into play. Of course general rule of thumb - the hotter it is outside, the less 3 way you use. The colder it is outside - the more you would use. Here in AR - in the winter - we mix trimec at 1 oz to gallon of H2O and it pretty well wipes out most everything it needs to, it takes some time due to colder temps, but eventually works fine.

we had the same cool weather here as well, but our post herbicide apps were further compounded by extremely dry conditions here, that is something else that should be taken into account.

in early may, we had browing broadleafs
