I read that "2,4-D" (in Weed and Feed) doesn't kill Flowering Weeds. Is this true?

I came across a gardening site that had this to say about products that use "2,4-D" (the active ingredent that virtually all granular weed controllers use such as Scotts Weed and Feed product line):



"Dandelions are readily controlled by 2,4-D, or products containing 2,4-D, if applications are made in fall or early spring before the plants begin to flower. After flowering begins, 2,4-D will twist and curl the leaves and flower stalks, but the plants often survive the treatment"



Is this true? If so then when i use a "Scotts Turf Builder with Weed Control" that contians 2,4-D which according to its instructions is to apply it when weeds are active and growing (so as to stick to leaves) then this isnt really killing them but "curling" them to look dead but arent realyl dead. Seems to me the best way to kill them is to pull them out of the ground and apply the 2,4-D product before they appear or after you pull them all (to prevent further infestations). Love to read your opinions.

That doesn't sound possible since nearly every weed will bloom if you just let it grow long enough.
Reply:Absolutely not true. 2,4-D kills any broad leafed weed. It does not kill thin blade grass. It doesn't care if a weed is blooming or not.
Reply:all plants are more susceptible to chemicals when they are flowering...additionally, they are easier to kill when they are dry (no water for a few days), or young...your lawn weed killers are designed to kill by leaf contact, in other words, the leaves need to be on the plant for the plant to ingest the chemical...if you can pull them by hand, it is much safer for you to do that rather than use the chemicals; if you do decide to use chemicals, be sure to wear your PPE (personal protective equipment)..gloves, long sleeves, pants...and don't allow pets or children on for a couple of days
