Lawn weed killers are different than general weed killers because of the active ingredient they use. Most weed killers such as Resolva Xtra Tough contain glyphosate. However, Resolva Lawn Weedkiller contains the active ingredients, Mecoprop-P, Dicamba and Potassium Hydroxide.
Mecoprop also called by its scientific name, (R)-2-(4-Chloro-2-methylphenoxy)propionic acid potassium salt is biodegradable. On the other hand, Dicamba is not biodegradable, so parts of the weedkiller will degrade in the soil while other will accumulate on the surface.
The active ingredients mentioned above are categorised as ‘hormone’ weedkillers because they impersonate plant hormones. The have a systemic action on the foliage of a weed and translocates down into the roots. Eventually, the active ingredients alter the plant’s hormones resulting in twisted or distorted growth.
Resolva lawn weedkiller is apt for controlling broad-leaved weeds such as buttercup, clover, dandelions, and daisy.
How to Use
Avoid using a lawn weedkiller on newly-turfed or seeded lawns for at least half a year after installation.
The best time to use Resolva Lawn Weedkiller Extra is from mid spring to early fall. Hence, April to September is the best time to use this lawn herbicide. Avoid using during windy conditions because it can cause the spray to drift. Also, check with your local weather station to confirm that no rain will fall within a 24 hour period of applying the herbicide.
For best results, make sure that the weeds are actively growing and have enough leaf area.
Here are the instructions for usage:
