Hey there! As a supplier of wettable powder (WP), I often get asked about the differences between wettable powder and other pesticide formulations. So, I thought I'd write this blog to clear up any confusion and give you a better understanding of what makes wettable powder unique.


Let's start by briefly going over some common pesticide formulations. There are a bunch of them out there, like emulsifiable concentrates (EC), suspension concentrates (SC), soluble liquids (SL), and granules (GR). Each has its own set of characteristics, advantages, and drawbacks, and they're all designed to meet different agricultural needs.
What's a Wettable Powder?
Wettable powder is a dry, finely ground powder formulation. It contains the active ingredient, along with some inert ingredients like wetting agents, dispersing agents, and fillers. When you mix it with water, it forms a suspension rather than a true solution. This suspension can then be sprayed onto crops using regular spraying equipment.
One of the big perks of wettable powder is its stability. It has a relatively long shelf - life compared to some liquid formulations. You don't have to worry too much about it degrading quickly if it's stored properly. Also, since it's a dry product, it's generally easier to transport and store. You don't have to deal with the risk of leakage like you would with liquid formulations.
Comparing Wettable Powder with Emulsifiable Concentrates (EC)
Emulsifiable concentrates are liquid formulations. The active ingredient is dissolved in an organic solvent, and an emulsifier is added. When you mix an EC with water, it forms an emulsion.
One key difference is the appearance. ECs are clear liquids before mixing with water, while WPs are powders. In terms of application, ECs can sometimes be more convenient for quick mixing as they dissolve rapidly in water. However, they have some drawbacks. The organic solvents in ECs can be harmful to plants in high concentrations, causing phytotoxicity. They can also be flammable, which poses a safety risk during storage and handling.
On the other hand, wettable powder is less likely to cause phytotoxicity. The risk is generally lower because there are no organic solvents. But mixing WPs can be a bit more time - consuming. You need to make sure the powder is fully dispersed in water to avoid clogging the spraying equipment.
Wettable Powder vs Suspension Concentrates (SC)
Suspension concentrates are also liquid formulations. The active ingredient is in the form of fine particles suspended in water.
SCs are ready - to - use in a sense that they're already in a liquid state. They usually mix easily with water and have good sprayability. But they require careful storage conditions. If they're stored at extreme temperatures, the particles in the suspension can settle or agglomerate, which affects the efficacy of the product.
Wettable powders, as dry products, are less affected by temperature variations during storage. They're also more resistant to freezing. However, as I mentioned earlier, getting a good suspension of WP in water can be a challenge, especially if the water quality is poor or if the mixing process is not done correctly.
Wettable Powder and Soluble Liquids (SL)
Soluble liquids are true solutions where the active ingredient is completely dissolved in water. They mix very easily with water and form a clear solution.
The main advantage of SLs is their simplicity of use. You just pour them into the spray tank, and they dissolve right away. But they often have a limited range of active ingredients that can be formulated in this way. Also, they might not be as stable as wettable powders over long - term storage.
Wettable powders, with their dry nature, can accommodate a wider variety of active ingredients. They're also less likely to break down over time, even if there are small variations in storage conditions.
Wettable Powder vs Granules (GR)
Granules are solid formulations where the active ingredient is incorporated into a granular carrier. They're usually applied directly to the soil or broadcast over the field.
Granules are great for soil - applied pesticides. They can provide a slow - release of the active ingredient, which is beneficial for long - term pest control in the soil. But they're not suitable for foliar applications.
Wettable powders, on the other hand, are mainly used for foliar spraying. They can quickly cover the leaves of plants, providing immediate protection against pests and diseases. And since they're in powder form, they can be formulated to have different particle sizes, which can affect the coverage and adhesion on the plant surface.
