SELECTIVE HERBICIDE
Selective herbicides kill specific, unwanted weeds or plants, whilst not damaging wanted plants. As such selective herbicides may be used on areas with mixed growth, for instance, controlling broad-leaved weed plants in fine turf.
Although cultural operations can do a great deal to reduce the severity of weed problems, weeds can be very tough and selective herbicides often represent the last line of defence.
Selective herbicides work in many different ways but in most amenity and sports situations the active ingredients, after application, penetrate the cuticle of the plant and are transported within the weed to their sites of activity where they employ a growth regulatory action. Resistant plants detoxify the herbicide or simply do not absorb it.
The correct dosage and application is important as this will determine which weeds are targeted.
Selective herbicides may be used to control such weeds as:
- Cat's Ear
- Greater Plantain
- Hoary Plantain
- Lesser Plantain
- Ribwort Plantain
- Sea Plantain
- Creeping Buttercup
- Daisy
- Dandelion
- Hawkbit
- Bird's Foot-trefoil
- White Clover
- Common Mouse-ear
- Selfheal
- Black Medick
- Lesser Trefoil
- Pearlwort
- Yarrow
