MCPA 750 Herbicide.
MCPA 750 is a selective phenoxy herbicide that was first introduced in 1945. It controls broad-leaf weeds but not grass weeds. It mimicks the action of the plant growth hormone auxin. This results in uncontrolled growth and then death in susceptible weeds.
It is taken up through the leaf and then translocates to the meristems of the plant. The result is uncontrolled, unsustainable growth that results in stem curl-over, leaf withering, and eventual plant death.
MCPA is more selective than 2,4-D, but it requires less 2,4-D to control many annuals. It persists 2–3 months in soil, whereas 2,4-D persists about 1 month.
Getting the Best Results from MCPA
- To get the best results use when weeds are actively growing.
- It takes about 4-6 hours with no rain to be sure it gets into the plant.
- Always ensure that the weed is actually susceptible to MCPA.
- Aim to apply to young plants.
- Make sure the weed is not under stress, drought or disease otherwise you will get poor results.
What MCPA 750 is good at.
MCPA 750 is very similar to 2,4-D but does not control the broad spectrum of weeds that 2,4 D controls. It is effective on tap-rooted weeds such as:
- Creeping Buttercup
- Dandelion
- Commelina
- Thistles
- Amaranth
- Hairy Bittercress
- and plantain. It also works OK vs White Clover and Yellow Wood Sorrel.
What MCPA 750 is not so good at.
MCPA 750 gives poor control of Mallow, Yarrow, Leafy spurge, Sedges, Speedwell, Ground Ivy and Wild Violet.

When should I apply my lawn pre emergent?
The best time to apply these products is in the early spring as this is before broadleaf weeds begin to grow. For grass weeds like summer grass apply later say in late spring or early summer. This weeds germinate later, so by applying your pre emergent later you will get longer control. -
What is a turf herbicide?
Turf herbicides, also known as weedkillers are pesticides used to control and manage undesirable plants. It is important that when you use a turf herbicide that you precisely follow the label directions. If you don't do this then the herbicide may fail to control the target weed, damage the turf grass or even prevent you from being able to reseed or re-turf damaged areas. Turf herbicides can be:- Selective or non selective. Selective turf herbicides are able to specifically target the weed without damaging the desirable turf grass. Non selective turf herbicides kill everything.
- Pre emergent or post emergent. Pre emergent turf herbicides prevent weeds from growing and becoming and are used before weeds grow. Post emergent kill weeds after they have emerged.
- Work against broadleaf weeds or grass weeds.
