An integral measuring device is inbuilt in the weedkiller bottle - remove the cap and carefully squeeze the container to fill the measurement chamber Can be used mixed with water for the more common weeds or undiluted those stubborn and harder to kill weeds. You can decide how strong you make your mix, up to a max dilution rate of 20%. In my experience, the product can be a little underwhelming at lower concentrations but is much more effective up near that 20% max. For this reason, I usually go for quite a strong mix when using Rootblast. What Will It Kill? Roundup 5 Litre Fast Action Weedkiller Pump n Go Sprayer– Ready to use, even comes with a sprayer, effective on young weeds.

WeedKil Fast Acting Weed Killer 5L– I use this for customers who don’t like to use chemicals, very effective and ready to use. It doesn’t kill the roots, so larger perennial weeds do grow again. Best used regularly on young weeds

It can also kill trees, especially if they are you, but can also damage established trees so be careful with how you apply this weed killer and don’t use it with a sprayer on windy days. Gallup Home & Garden Glyphosate Commercial Strength Weedkiller– The strongest weedkiller with 360 g/l of Glyphosate and what I use professionally. Very effective and long lasting! – The best for all surfaces including driveways It kills weeds on and below the ground, ensuring that they do not regrow again in a few weeks time.

All this does come with a trade-off, though. Glyphosate requires special care in its handling and careful attention to all safety instructions. It’s also not safe for children, pets and wildlife to be around it until its dry. Don’t forget to wear gloves and a mask, and be careful where you spray this non-selective weed killer, as it kills everything it touches that is green. It is a systematic herbicide, meaning it seeps its way into the foliage and down to the root system where it destroys the enzymes responsible for plant growth. This makes it a great choice for controlling deep-rooted weeds. There are numerous different methods you can use to apply Rootblast. Many people buy a sprayer and use that, while this is great for paths and patios it doesn’t work well for spot weed killing in and amongst your beds. This is because the mist can be carried in the air to plants you didn’t want to kill. Weeds that grow on our driveways can be tough to control, but specialised herbicides can help eliminate them and prevent regrowth. We want to believe that this in-depth review has informed you enough about choosing the best weedkiller for drives and paths.This herbicide needs to be diluted with water before application and a sprayer will definitely come in handy. The product is biodegradable so it does not prevent cultivation, especially when used on the farm. Note that rain can wash away this weedkiller, therefore, make sure to conduct this exercise in dry weather. Emergence –weedkillers can be pre-emergence or post-emergence. Pre-emergence weedicides are used for targeting germinating seedlings before they grow, while post-emergent products work on weeds that have started growing. Here we have four different characteristics; selectivity, emergence, persistence and translocation. This is a tough question to answer as it can vary depending on the plant. For me when I used it on dandelions the weeds started looking unhealthy after a day and had gone yellow in three days before fully dying after about a week. Because it will kill anything it touches it is not suitable for use on lawns as it won’t only target the problematic weeds, it will kill all your grass as well. How to Apply

Rootblast is a Glyphosate based weed killer, so if you garden organically then this isn’t the weed killer for you. If, however, you just want the maximum weed-killing power then this might well be the product for you. There are many types of weeds. In this review, we will differentiate weedkillers by these two aspects; characteristic and application. Weedkillers by characteristic Weeds compete with desired plants for sunlight, water and precious nutrients. In a farm situation, weeds can greatly reduce crop yields because they give food to pests that harm desired plants. They also can host plant bacteria, which can degrade the soil as well as cause root damage. To be really targeted you can actually spot-apply this weed killer. this just means you apply it directly to the targeted weed using something like a paintbrush. If you are going to do this just be careful you don’t get the weedkiller on your skin and use gloves if possible! When it comes to mixing, for spraying a patio or weeds in general, you need to mix 15ml of concentrate per litre of water, so if you have a 10-litre sprayer, mix 150ml with 10 litres of water. Each litre should treat about 25 square meters with a sprayer. Just make sure you are patient when you’ve applied this Rootblast weed killer, as it doesn’t show the effects as fast as the Gallup weedkiller does as it is mixed at a slightly weaker ratio. I find it takes around 7 days to start showing. However, it often takes about 3 weeks for the weeds to become brown and die. Remember that this weed killer gets right down into the weed’s roots, and that takes time as well.

The Roundup Ultra Weedkiller Concentrate Bottle contains a super-concentrated formula that makes it perfect for eliminating those tough weeds from our driveways, paths and patios. It actually does more than that, including clearing weeds around walls, fences, trees and shrubs. Pressure washing of hard surfaces gets rid of small weeds and moss, as well as clearing residues of soil and organic matter that would provide seed beds for weeds It works by diluting the concentrate with water though you can still apply straight from the sachet to destroy stubborn woody weeds so would be good for killing horsetail by using straight from the sachet. It is a systematic weedkiller that contains ammonium salt of glyphosate. Once the herbicide is absorbed on unwanted plants, it is carried throughout the plant system by sap, down to the root where it starts to work. Effects are visible in 1-2 weeks so patience is needed with this one, but this is the price you pay for excellent results.

The Resolva 5 Litre 24H Ready to Use Power Pump Weedkiller works as it should and is especially effective on dandelions. You can opt for the mini spray bottles to treat smaller areas but you’d be better off with the 5L for areas up to 200m2. The manufacturer says themselves that it can take from a few days up to 4 weeks for the weeds to fully die. ConclusionThe weed killer comes as a concentrate which you dilute down and can then spray/water onto your weeds. Just a little note here, this stuff can hang around in your sprayer/watering can even after rinsing them out, so never use the same watering can that you use for your plants! Also known as soil acting herbicides, we would not advise using these weedkillers on your farm or in your garden as they sit in the soil for several months, inhibiting any form of growth from happening. Some of them can poison the soil and render it useless for cultivation. Avoid using these herbicides in areas that you intend to grow crops in the next two years or more. I’ve been involved in garden maintenance and worked at my family’s nursery for over 20 years. I’ve also had my chemicals spraying licence for as long which I need to spray weedkillers professionally. Now most professional-grade weedkillers are not available to the general public. However, there are a few that are just as strong and very effective that are still available. Works on many kinds of weeds including tough woody weeds that most other ready to use weedkillers won’t even touch. This Gallup Commercial Strength Weedkiller works on a variety of weeds but it does take a week or two to see the results. This is my favourite weedkiller and I’ve used it for over 15 years and have never had any issues. Very effective and works great on all surfaces including hard and gravel driveways.
