ProForce Manta Ray Adjuvant


ProForce Manta Ray Adjuvant.

ProForce Manta Ray Adjuvant ProForce Manta Ray Adjuvant contains the active ingredients 350g/L Soyal Phospholipids and 350g/L Propionic Acid. It is a unique, multi-purpose surfactant that enhances performance of herbicides, insecticides, fungicides and PGRs.

ProForce Manta Ray Surfactant also acidifies the spray tank solution, reduces losses due to alkaline hydrolysis and assists with the uptake of weak acid herbicides.

ProForce Manta Ray Surfactant also assists in droplet size management to partially reduce spray drift from use of hydraulic nozzles by air and ground spray equipment.

It is an excellent tank mix partner for herbicides and fungicides like Voltar 500SC, and it increases herbicide uptake and activity on difficult to penetrate weeds including “woody weeds”.

When you use this as a spray adjuvant it improves coverage, penetration and uptake of herbicides, fungicides, insecticides, miticides and foliar nutrients.

Most turf pesticides are stable in water with a pH less than 8, but some like Carfentrazone, 2,4-D and Iprodione (Voltar 500) break down (due to alkaline hydrolysis) quickly in high pH water (pH > 8), and prefer a spray pH less than 7.

Water hardness can also be a problem when a weak acid herbicide is used, but hardness is not known to cause problems with the fungicides, insecticides, and plant growth regulators in use on turf. Water hardness causes problems with the amine formulations of weak acid herbicides when the cations bind to the herbicides, and reduces their effectiveness.

Glyphosate is the best example of a weak acid herbicide that is antagonized by hard water, but water hardness is known to work against other weak acid herbicides like 2,4-D amine, Bentazone, Dicamba, Glufosinate, MCPA, and Quinclorac.


Benefits of ProForce Manta Ray Adjuvant.

  • Approved for aquatic use and you can use this for weed control in aquatic situations. It works well with Glyphosate (Rapid Fire), Flumioxazin, Diquat, Amitrole and other aquatically approved herbicides.
  • Non-ionic surfactant. Doesn’t have negative reactions with pesticide chemistry.
  • Made from natural materials – soybean oils.
  • Acidifies the spray solution to reduce spray tank issues caused by alkaline hydrolysis and enhances uptake of weak acid herbicides.
  • ProForce Manta Ray is an ideal tool to manage drift. It reduces the number of fine droplets that nozzles produce.
  • Available in multiple pack sizes – 1L, 5L and 20L.


pH adjustment procedure in sample jar:

  • Take an eyedropper, add 3 drops of Manta Ray to a Litre of water.
  • Stir well.
  • Use a pH metre to check the water pH.
  • If you need to make further changes, repeat steps, until the pH is where you want it.
  • Note the number of drops you add to bring the solution to the pH that you need.

pH adjustment in spray tank:

  • Check the pH of the Tank Water.
  • Add Spray Tank Buffer at the label rates.
  • Recheck the pH of the Spray Tank Water
  • Add other Spray chemicals.


Buffers will improve how well your chemicals and PGRs work. In the long term, this reduces the number of sprays you make, reduces chemical resistance, and saves money.

  • What is the chemical half life of a spray mix?

    The chemical half-life is the amount of time it takes a pesticide to decay to half its original concentration. How quickly the pesticide degrades due to hydrolysis depends on pH, temperature, and to a lesser degree water hardness. Each half-life that passes reduces the amount of pesticide in the water by one half, i.e. 100% to 50% to 25% to 12.5% to 6.25%, etc. 
  • Can i use washing up liquid to make my weedkiller work better?

    No you can't. Detergents are a cleansing agent, usually consisting of salts of long-chain aliphatic bases or acids that exert cleansing or oil dissolving and antimicrobial effects through a surface. These nonionic and anionic surfactants, can cause turf injury and also cause a reduction in weed control.
    Detergents are great for cleaning dishes and removing grease and grime. They are not designed to stick herbicides to plants or assist in forcing the herbicide into the plant so it can be translocated to the root system.
    The detergent’s mode of action is to dissolve grease and grime and can adversely impact the active ingredients mixed in spray solutions.
  • Do I need a spray adjuvant to get a good result?

    Any time you apply chemicals, read the label before you use them. This protocol is the same with spray adjuvants and even more so when using spray adjuvants with herbicides. Some products already contain adjuvants, so you do not need to add any more. In fact, adding more can result in a loss in performance.  However, if it says on the label to use an adjuvant, you won't get the best results unless you do. Good examples of products where adjuvants are worth considering to give better chemical performance include:
    1. Iprodione-based fungicides such as Voltar 500. Use a spray buffer, like Manta Ray buffer, to reduce the water pH. Iprodione is susceptible to alkaline hydrolysis at a pH of 7 and above.
    2. Herbicides like Sulfonylureas. Ideally, you should use a non-ionic surfactant like Scrubwet to give better chemical contact with the leaf.
  • If I use a spray adjuvant at the label rate, will adding more give better results?

    More is not always better and and with chemical adjuvants this most certainly is the case. The rates on a label are there for a reason. Adding amounts above the label recommendations will potentially cause damage to non-target plants and pollution of the groundwater.
  • Can I use pond water, salt water, or well water for a spray tank mix?

    Water quality has an impact on the results of using turf chemicals. The most important of these are the water pH and water hardness. You should always use clean water that does not contain suspended soil etc. These ions can neutralize some herbicides or stop some adjuvants from working. Also, in Australia, tap water is artificially raised to around 8. At this level, it has a negative effect on herbicides like glyphosate and fungicides like iprodione. Do not use salt water, as it contains antagonistic salts and ions that can make a mix useless.
  • What is the difference between a spray adjuvant and a surfactant?

    Spray adjuvants are added to the spray tank to make the active ingredients being used work better. A surfactant is an adjuvant that improves the dispersal, spreading and wetting of a product.
  • How can you increase the viscosity of spray mixtures?

    Surfactants change the structure of waxes on leaves and stems, so that turf chemicals can enter more easily. There are also several drift reducing products that increase the viscosity of the spray mixture. Increasing the viscosity of spray mix is useful when you do not want to get any spray drift into sensitive areas.
  • How can I tell if products I have not used before can be mixed together?

    The product label gives information about adjuvant use. If specific information about the products you want to mix is not on the label, it is going to be wise to contact the manufacturer before you do any mixing. If you are still in doubt conduct a jar test, which will let you know if they are compatible.
