Working mechanism

Let’s take a look at how it works

Weedol is a selective weedkiller that targets broad-leaved weeds such as dandelions, daisy, clover, bindweed, chickweed, common mouse-ear, thistles, lesser trefoil, plantain, cleavers, creeping buttercup, black medick, and hogweed to name a few. It only targets the weed and not the surrounding lawn. It kills the weeds from the roots so that they no longer compete with the turf for water, nutrients, and sunlight.

Weedol lawn weed killer has the edge over the competition because it uses three different selective weedkillers.

They are:

• Fluroxypyr
• Clopyralid
• MCPA

These active ingredients are known as hormone type herbicides. They work through a systemic action once contact is made with the leaf (foliar) to translocate into the weeds roots. From there it impersonates special plant hormones that cause the weed to grow in a twisted and distorted way, essentially killing the weeds.

After application, weeds will begin to decompose with a brownish colour and eventually die within a total timeframe of 4-6 weeks. It removes the competition from the weeds and lets the grass thrive and spread.

How to Use

Knowing how to use the Weedol Lawn Weedkiller correctly will determine what kind of results you will see. For this reason, it is imperative to check the label and safety data sheet supplied with your purchase.

This herbicide effectively controls small and large broad-leaved weeds.

Only one treatment is needed per season. The best time to apply this weed killer is between the months of April and September. This is the period when plants are actively growing and producing long leaves. The long leaves help the spray to translocate through the weed to reach its roots. For best results, avoid mowing the lawn a few days before and after treatment.

Check with your local weather station to determine if it will rain within a 24 hour period of the treatment. Rain lessens the effectiveness of the weed killer and promotes run-off and drainage contamination. Furthermore, avoid drought and frost conditions. Wind is also a problem because it can cause the spray to drift.

When dealing with a new land, wait at least two months after sowing or laying turf before applying Weedol. Also, avoid using clippings from the first lawn mow after application as compost. The next three mows should be composted well for a minimum of nine months before being used as a mulch. Allow short clippings to remain on the lawn that will decompose to leave a great looking lawn.

To use, follow these instructions:

1. Get a watering can with a fine rose or garden knapsack sprayer ready
2. Measure 15 millilitres of weed killing solution and mix it with 5 litres of water in the sprayer. To make the mixture stronger, reduce the amount of water to as low as 1 litre.
3. Begin spraying and treat up to 10 square metres
4. After use wash all tools thoroughly with water but prevent run-off.

Safety Precautions

When handling this product, there are some safety precautions you will need to take into consideration.

• Avoid spraying the weed killer on desired lawn areas
• Wear protective gear including gardening gloves, overalls, face mask, eye goggles, and boots.
• Keep container securely closed in a safe place at room temperature.
• Do not let children or pets enter the treated area until the spray is dry
• Dispose empty containers at a hazardous waste centre or civic amenity site.

Benefits

• Kills weed without harming the lawn
• Kills broad-leaved weeds from the roots
• Ready to use with no need for mixing (except the concentrated model)

Working Mechanism

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:

If you buy the ready to use model then there is no need to mix anything, you can simply start spraying. However, if you choose the concentrate version then the instructions are listed below:

1. Read the label and safety data sheet supplied with your purchase
2. In a knapsack sprayer, pour 50 millilitres of Resolva concentrate and mix with 2.5 – 5 litres of water.
3. Begin spraying on affected areas. A single batch of the mixture can treat up to 25 square kilometres.
4. Wash equipment thoroughly after use.
5. Do not mow the grass for a couple of days. The first four mowings of treated lawn need to be composted for half a year before using as a mulch.
