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.
- 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.
- 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.
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.

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.
- 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
- Slow action
- Not selective, kills any plant immediately, if sprayed or made contact in substantial amount
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!
