Water Conditioner to Acidify Spray Water and Handle with Hard Water Pro-Buffer S2 in Solid Form

Pro-Buffer S2 is a water conditioner in solid form, which can acidify the spray water and sequester metal ions in hard water.
Key Benefits:
- To reduce pH value by approximately 1.5, which will benefit most pesticides 
- To tie upon different types of hard water cations before they can bound with pesticides, especially weak-acid herbicides, thus keep - herbicides in active form and give more consistent weed control 
- To lower the risk of pesticides failure and the added costs when it happens 
- Low use rate of Pro-Buffer S2 @0.07%-0.2% compared to solid AMS @2%
Product Usage:
Tank mix use
1) Read and follow directions for use on pesticide labels. (It is recommended to use test areas if possible.)
2) Test pH and hardness of water to choose the suitable use rate of Pro-Buffer S2.
3) Fill spray tank half of water and begin agitation.
4) Add desired rate of Pro-Buffer S2 to water before adding pesticides.
5) Add pesticides, as directed by label, while maintaining agitation. (If pesticide label recommends the addition of a surfactant, follow instructions accordingly.)
Recommended Use Rate:
 Water hardness level Use rate
 <200 ppm 0.07% m/v
 200-400 ppm 0.1% m/v
 >400 ppm 0.2% m/v
Specification:
 Appearance Yellow liquid
 Active Content, % ≥85
 pH range (1% aqueous solution) 4.0-6.0
Packing: 25kg/bag, etc.

Water Conditioner to Acidify Spray Water and Handle with Hard Water Pro-Buffer L2 in Liquid Form

Pro-Buffer L2 is a water conditioner in liquid form, which can acidify the spray water and sequester metal ions in hard water.
Key Benefits:
- To reduce pH value by approximately 1.5, which will benefit most pesticides 
- To tie upon different types of hard water cations before they can bound with pesticides, especially weak-acid herbicides, thus keep - herbicides in active form and give more consistent weed control 
- To lower the risk of pesticides failure and the added costs when it happens 
- Low use rate of Pro-Buffer L2 @0.2%-0.8% compared to liquid AMS @1% 
- Easy-to-use liquid formulation
Product Usage:
Tank mix use
1) Read and follow directions for use on pesticide labels. (It is recommended to use test areas if possible.)
2) Test pH and hardness of water to choose the suitable use rate of Pro-Buffer L2.
3) Fill spray tank half of water and begin agitation.
4) Add desired rate of Pro-Buffer L2 to water before adding pesticides.
5) Add pesticides, as directed by label, while maintaining agitation. (If pesticide label recommends the addition of a surfactant, follow instructions accordingly.)
Recommended Use Rate:
 Water hardness level Use rate
 <200 ppm 0.2% v/v
 200-400 ppm 0.4% v/v
 >400 ppm 0.8% v/v
Specification:
 Appearance Yellow liquid
 Active Content, % ≥50
 pH range (1% aqueous solution) 6.0-7.0
 Viscosity, cps 30-80
Packing: 200kg/drum

Water Conditioner Pro-Buffer to Acidify the Spray Water and Handle Hard Water

As we talked in my former article that water quality is often mistaken as a minor factor in overall efficacy of pesticides efficacy while it do affect the pesticide performance.
Water hardness and pH are the two main characteristics of water quality that impact on the efficacy. And I'm excited to introduce the adjuvant Pro-Buffer S2 and Pro-Buffer L2 developed by Profirst, water conditioners in solid form and in liquid form respectively, which are designed to reduce pH value and handle hard water.
For more information, please check the slide as below:

Water Quality in Agrochemical Spraying Will Affect the Product Efficacy

Water accounts for more than 90% in the agrochemical spraying solution. As the foundation of the spraying process, water is overlooked in many cases.
Several key elements about the water quality which will affect the spraying performance:
  • Water hardness
Some negatively-charged pesticide molecules can attach to the positively charged cations,if present in water,like Al+++, Fe+++, Fe++, Mg++, Ca++, Na+. The cations listed are in the order of most potential to bind to pesticides.
This binding leads to the reduction of the solubility, which resulting in the pesticide molecules unable to penetrate the leaf tissue or target pest, or enter at a much lower rate. Thus the performance of pesticides is largely reduced. In other cases, the hard water can cause some chemicals to precipitate and affect the properties of surfactants in the formulation or adding in tank mix, thus may block nozzles and pre-filters and cause additional wear of spray rigs.
Measurements of hardness are given in terms of the calcium carbonate equivalent, which is an expression of the concentration of hardness ions in water in terms of their equivalent value of calcium carbonate. The greater the concentration, the harder the water.
Many herbicides carry a negative charge, such as glyphosate, glufosinate ammonium, 2,4-D, and other weak-acid products.
So next time if the Glyphosate did not perform well, in addition to the reasons of resistance, short dosage, etc, you should consider about the hard water.
Solution
The most commonly used water conditioner is ammonium sulfate (AMS). AMS in solution disassociates, and the sulfate binds with cations in the spray solution, preventing the development of glyphosate-cation complexes that tend to have lower absorption into plant leaves. In addition, the ammonium ion can associate with the glyphosate molecule, which helps facilitate glyphosate absorption into the leaf.
Also some sequestering or chelating agents can be used to remove the antagonistic ions by holding cations and prevent attachment to herbicides.
  • Water pH
The pH value of the water may affect the stability and efficacy of pesticides.
Pesticides normally are formulated as weak acids, or neutral to weak alkaline products. Generally, pesticides perform best in slightly acidic water, pH 4-6.5. Pesticides such as sulfonylurea herbicides perform better in water that is slightly alkaline.
A higher or lower than optimal pH range can cause some pesticides degradation or breakdown. This process of hydrolysis is usually permanent and irreversible, which will reduce the life of pesticides in solution, affect the physical properties of some formulations and reduce the efficacy. Besides, deposits in pipes and blockage of equipment(high pH case), and corrosion of metal pipes and fittings(low pH case) can happen.
Solution
Use buffer to get an idea pH. Acid such as sulphuric or phosphoric acid lowers pH while alkaline such as potassium hydroxide increases pH.
  • Water turbidity
Sometimes the water from ditch, river or ponds are visibly muddy. This kind of water may contain suspended particles of clay, silt and fine organic matter. The effectiveness of herbicides such as glyphosate and paraquat are reduced once they are binding to the suspended sediments, rendering them unable for plant uptake. And muddy water which is not sufficiently filtered can cause equipment problems.
Solution
Filter the water before filling into the spray tank. Heavy particles can sink into the bottom in a settling tank, while very light particles can be settled out by using some certain surfactants.
Testing of spraying water quality is far from the above contents, other items like temperature, salinity, etc can also affect the spraying performance.
Always read the label before using the pesticide!
