In the niche of the most powerful weed killer, Rosate 36 green has been stirring some discussions due to its effectiveness and strength. It is promoted by the manufacturing company as a self-degrading chemical in soil. It is ideal for contract spraying, and management of large areas.
If you own a farm, a large garden or are in landscaping or weed control business, the Rosate 36 will intrigue you. The herbicide comes in a soluble liquid concentrate form and is apt for most species including annual and perennial grass and broad-leaved weeds.
It competes with Gallup 360 for the title of a strong industrial weed killer.
Getting Familiar with Rosate 36
As seen on its label, it is a soluble liquid herbicide containing 360 g/liter glyphosate acid present as 480 g/liter (41.5% w/w) isopropylamine salt and polyoxyethyleneamine surfactant. The herbicide is a foliar-applied, translocated herbicide for the control of annual and perennial weeds in a range of agricultural, horticultural, forestry, industrial, amenity and aquatic situations.
Available in:
- Rosate 36 – 1L (Glyphosate)
- Rosate 36 – 5L (Glyphosate)
- Rosate 36 – 20L (Glyphosate)
A peek into using the herbicide Rosate 36
- Apply in a minimum of 50L water
- Coverage Rate: 5L Rosate treats 10,000 sqm
- Dilution Rate: 1-3L Rosate to 50L water
Overview: Working Mechanism
The Rosate 36 contains an active ingredient glyphosate, which is helpful in controlling most species of emerged annual and perennial grass and broad-leaved weeds.
It is readily absorbed by foliage and seeps into the growing points in the roots. When used under food growing conditions, it is fast and effective. It kills the weed from tip to root and prevents any regeneration or regrowth.
The glyphosate is adsorbed onto the soil particles after it eaves the roots and is completely degraded by microbial activity after coming in contact with the soil. This facilitates sowing of new plants fruitful with elimination of weed and disposal of any herbicide present in soil.
Covered Spectrum
The herbicide is not selective and is effective on almost all common garden weeds, and it kills plants too! So, be careful in its application. The weeds covered by the Rosate 36 are:
- Crops: Wheat, durum wheat, barley, oats, oilseed rape, combining pea, mustard, field bean, linseed, sugar beet, swede, turnip, onion, leek
- Other usages: stubbles of all crops, grassland, hard surfaces, and natural surfaces not intended to bear vegetation, permeable surfaces, and overlying soil
- Land preparation: all edible and non-edible crops (destruction of established vegetation prior to sowing or planting), apple, pear, plum, cherry, damson,
- Aquatic environments: enclosed waters, open waters, land immediately adjacent to aquatic areas, forest and farm forestry (weed control and chemical thinning by stump application and injection).
What Garden Sprayer Should You Use?
Since concentrated glyphosate weed killers aren’t pre-dilluted or include a sprayer, you’ll need to buy one separately. The best garden sprayers to be used along this herbicide are:
- Faithfull SPRAY16 16 litre Pressure Sprayer
- Hozellock 7L Garden Sprayer
- Am-Tech 8L Pressure Sprayer
All of the sprayers listed above include a product warranty.
Suggested Usage
Weeds and unwanted plants are most susceptible to Rosate 36 while they are actively growing. Best environmental conditions for its use are warm, humid conditions with adequate soil moisture. Weeds that lag behind in growth or are affected by dry conditions, water-logging, high temperatures or frost are least affected by the herbicide. Any restriction in proper uptake into the plant reduces its effectiveness.

Ingredients
The 360g/L glyphosate is a revolutionary ingredient, if we believe at what company claims. It kills weeds from tip to root and is readily decomposed by bacteria in soil – removing any traces of herbicide after treatment. This makes it environment friendly too.
Application Rate (Efficiency)
The concentrate is cost effective since it needs a small amount to effectively treat a very large area. The 20 L pack is enough to treat 209 hectares. Following is the amount needed with respect to method and area of application.
- Knapsack Sprayers: Apply in 100-300 liters of water per hectare as a MEDIUM or COARSE spray (BCPC)
- Example spray dilution calculation: To apply 5.0 liters per ha of Rosate 36 in a water volume of 200 liters per ha in a sprayer tank of capacity 5 liters, ass 125ml of Rosate 36 to 4.88litres of water in the sprayer tank.
- Hand Held Weedwipers: Use a concentration dilution of 1 part Rosate 36 to 2 parts of water. Do not exceed this maximum concentration and add a water based dye if necessary.
Pros
- Cost effective
- Easy application with detailed instructions for coverage area
- Gets decomposed by bacteria, leaving any traces of herbicide
- Kills from root to tip
- Pet friendly once product is dry
Cons
- Slow action
- Not selective, kills any plant immediately, if sprayed or made contact in substantial amount
Verdict
The Rosate 36 might not seem like a must have item for all gardeners, but is especially beneficial to large scale farmers, landscaping professionals and persons who practice weed control as profession. It is cost effective, covers a whole range of weeds and eliminates the problem from tip to root!
Do I need to exclude my dogs, ducks and chickens from the sprayed area?
Thank you. I have found your information really useful.
Hi Liz, pets should be kept away from the area until it is dry.
What dilution rate should I be using for rosate36 on grass and bracken and broadleaved weeds, docks etc
.I am appalying using a 10/12 litre back pack sprayer
Is there any problem in its effectiveness with applying it in too concentrated a form ??
Hi Bob, according to the manual the appropriate dilution amount would be 6 liters. Anytime you are treating weeds, it’s suggested to start with a lower concentrate and work your way up according to the results.
david I just put in a small orchad of paicicto and was about about appling 15x15x15. as you talked about almont you mention not appling more the 1 once of nitrogen at 18 from the trunk. How do I determine how much triple 15 to put around each tree to not exceed the 1 ounce?

Hello Paul, yes it is a great bindweed killer and can eradicate very effectively.
Hi can I use Rosate along my hedge row privit & hawthorn & will it kill ivy growing through the bottom of hedge. Spraying with 5ltr hand held pump sprayer.
Thanks
Yes William, it is capable of removing ivy weeds.
will this be suitable to kill weeds around rose or will that take out the rose too ( foliage removed already
Hello Gary, yes it it can kill all types of weeds. However, because it is non-selective it will likely kill the roses to. A solution to this problem is to buy the hozelock weed killer which will allow you to treat the weeds one-to-one.
HOW LONG DOES IT TAKE TO BE RAINFAST ?
Hello Tom, it begins to work the moment you spray it. For best results, it may take up to a week to show.

Alan
Hello Alan, it can kill laurel bush and bamboo, and other weeds such as Japanese knotweed, very effectively.
In the past I have used proprietary products containing Ammonium sulphamate
for small stumps, heaping up the crystals on the cut surface and covering with a plastic
bag. How should Rosate 36 be applied in this instance?
Hi Mike, Ammonium sulfamate is best for removing woody plants, tree stumps, and bramble. Glyphosphate based weed killer work best for plant type weeds such as perennials.
Will it kill the grass or just the weeds
Hello Gary, it is a non-selective liquid weed control concentrate and can kill your grass if you apply it there. Our advice is to use the hozelock wonder weeder to target only the areas where non-wanted plants are growing.
Can you use this product on tennis courts to remove moss growth
Hello Carl, you may want to take a look at moss killers here.

Is there anything I can add to Rosate 36 to permanently kill off the growth of weeds on my driveway?.
Rosate 36 only works for short periods
Hi Mark, You can add paradise to the glyphosate mix which is a residual weedkiller and lasts around 6 months. You would need to add 2.5 grams of paradise to a 5 litre tank of mixed solution.
I have large mounds of onion weed that my research says are hard to kill. Will Rosate 36 be enough? I also have individual onion weed bulbs near plants I want to keep. Can I isolate the good plants by protecting them and still spray the onion weed and will that above ground protection be enough to save the good plants?
Hi i have sprayed my grass which has a lot of weed growth how long before my dogs can go back in the garden and when can i resow or returf thanks
Hi
Can I use this to treat inside a polytunnel before planting in it???
Hello Alison, it is 1-3 litres of Rosate 36 for every 50 litres of waater
I use 125ml in 5 litres of water.
Hi I am a gardener basically maintaining gardens drives patios etc. Can this be used to kill unwanted weeds on paths, drives, patios and gravel from a watering can at 20ml/1l ration? I do have a pump sprayer available also. I am tired of buying clients boxes and boxes of weedkiller and now look to buy in bulk if this suits the above needs. many thx Tony
Hi Tony, I use this in all the gardens I work in and it works effectively on gravel, paths and patios just as well. I would recommend using a pressure sprayer for even and more cost effective results using 25ml per litre of water.
Hi, will this kill flower bulbs? Thank you 🙂
Hi, will it kill horsetail?
Hi Peter. The basic answer is no… You would need to look for a weedkiller called ‘Kurtail’ to eradicate mares tail. Rosate will just brown off the surface growth , but doesn’t translocate throughout the root system as well as kurtail.
Hi
I was wondering how effective this would be on grass growing in a menage of sand and fibre and also how long it would be before it was safe for horses to exercise in it?
Thank you
Hi Karen, Rosate will work very well on all kinds of grasses and you can exercise the horses once the spray has dried completely.
Will roseate kill bamboo
Yes, any weed killer containing Glyphosate should work.
