Pesticide Formulation Determines Efficacy: AGROFEAST Explains WP, SG, EC, and EW — Choose the right formulation to maximize the value of every drop.
Why Does Formulation Matter So Much?
When selecting crop protection products, many farmers focus primarily on the active ingredient and the application rate, often overlooking an equally critical factor — the formulation.
In reality, even with the same active ingredient, different formulations can deliver significantly different levels of control.
Formulation not only determines whether the spray solution can be applied evenly, but also directly influences:
· The ability of the spray liquid to adhere to and cover the leaf surface;
· The speed at which the active ingredient penetrates weeds or insect pests;
· The stability of the product during high-temperature transportation and long-term storage;
· Crop safety and the final efficacy of the treatment.
For Nigeria, the combination of high temperatures, long-distance transport, and the wide variation in spraying equipment makes the choice of formulation even more critical.
Currently, the most widely used and popular formulation types on the market include:
✅ Wettable Powder (WP)
✅ Soluble Granule (SG)
✅ Emulsifiable Concentrate (EC)
✅ Emulsion in Water (EW)
Let AGROFEAST take you through the characteristics and application value of these four common formulation types.
Chapter 1 | Wettable Powder (WP)
A classic, reliable, and cost-effective choice.
WP (Wettable Powder)
Wettable powder is one of the oldest pesticide formulation types. It is made by thoroughly mixing the active ingredient with fillers, wetting agents, and other excipients, followed by a grinding process. Before use, it is mixed with water to form a uniform suspension for spraying.
Key Advantages
✅ Low cost and economical
✅ Excellent stability under high-temperature conditions
✅ Long shelf life, resistant to decomposition
✅ Suitable for a wide range of crops
Common Drawbacks of Traditional Products
❌ Relatively large particle size, leading to average suspensibility
❌ Tendency to generate dust
❌ Potential for sedimentation after prolonged standing
❌ Risk of nozzle clogging with some products
The AGROFEAST Technology Upgrade
AGROFEAST, backed by the advanced formulation platform of its parent company KESAI AGROCHEM, utilizes a pharmaceutical-grade, high-altitude nano air-jet milling technology to perform ultra-fine grinding of the active ingredient particles.
Compared to traditional powders:
· Finer particles;
· Superior suspensibility;
· More uniform coverage;
· Faster absorption;
· More consistent efficacy.
When the spray liquid deposits on the surface of weeds or pests, the active ingredient can take effect more rapidly, achieving a more thorough control.
Recommended Product

Flumioxazin 6% + Glufosinate-ammonium 60% WP
Product Features:
· Dual-action contact and systemic mechanism
· Nano-sized ultra-fine particles
· Fast weed burndown
· Outstanding efficacy against tough weeds
Chapter 2 | Soluble Granule (SG)
Dissolves instantly for easier use.
SG (Soluble Granule)
Soluble granule is a new formulation type that has gained significant popularity in recent years.
Unlike Water Dispersible Granules (WG), SG products dissolve completely in water to form a true solution, not a suspension. This means there are no issues with sedimentation or nozzle clogging.
Key Advantages
✅ Fast dissolution rate
✅ Dust-free, no pollution
✅ No risk of nozzle clogging
✅ Easy to handle and transport
✅ Safe to use
AGROFEAST's Exclusive "Deliquescent Secondary Absorption Technology"
AGROFEAST's innovative "Deliquescent Secondary Absorption Technology" further enhances the utilization rate of the active ingredient.
After spraying, the liquid forms a uniform film on the leaf surface.
During the day, as the weed absorbs the active ingredient, the residual film can re-absorb moisture from the air when humidity rises at night. This causes a slight deliquescent effect, prompting the active ingredient to be released again and continuously absorbed by the plant.
This means:
· The portion of the product not fully absorbed during the day is not wasted;
· The product continues to work effectively through the night;
· Weed death is more complete;
· The risk of regrowth is significantly reduced.
Furthermore, AGROFEAST's dual-adjuvant high-adhesion and high-penetration system effectively enhances the spreading and translocation of the spray liquid on the leaf surface, accelerating the transport of the active ingredient to the root system and achieving a true "root-and-shoot" kill.
Note: The deliquescent effect can be influenced by environmental factors such as humidity, temperature, and leaf surface conditions.
Recommended Product
EASYCLEAR
Glyphosate-ammonium salt 88.8% SG
Product Features:
· Deliquescent Secondary Absorption Technology
· Thorough weed control with no regrowth
· Dust-free granules for safer handling
· Fast systemic translocation
Chapter 3 | Emulsifiable Concentrate (EC)
Strong penetration and rapid action.
EC (Emulsifiable Concentrate)
Emulsifiable concentrate is one of the most widely used pesticide formulations in the Nigerian market.
It involves dissolving the active ingredient in an organic solvent and adding an emulsifier system. When mixed with water, it forms a milky-white emulsion.
Key Advantages
✅ Strong penetrating ability
✅ Fast onset of action
✅ Excellent adhesion properties
✅ Good rainfastness
✅ High cost-effectiveness
For most weeds, visible symptoms of phytotoxicity can be observed within 24–72 hours after application, making it a firm favorite among farmers.
Limitations of Traditional ECs
❌ Relatively high content of organic solvents
❌ Strong odor
❌ High volatility
❌ Potential risk of phytotoxicity on sensitive crops
The AGROFEAST Upgrade
AGROFEAST employs a high-purity active ingredient synthesis process, controlling the impurity content from the source to achieve a product purity far exceeding the industry average.
At the same time, the company innovatively uses an environmentally friendly oil-based adjuvant system to replace traditional aromatic hydrocarbon solvents.
The benefits include:
· Safer for crops
· More environmentally responsible
· Lower volatility
· More uniform spreading
· Reduced risk of phytotoxicity
After spraying, the liquid forms an even film on the leaf surface, effectively avoiding localized scorching caused by droplet aggregation.

Chapter 4 | Emulsion in Water (EW)
The eco-friendly upgrade — a top choice for fruit and vegetable crops.
EW (Emulsion in Water)
An Emulsion in Water can be seen as the environmentally advanced version of an EC.
It replaces most of the organic solvent with water, with the active ingredient dispersed as microscopic oil droplets uniformly suspended in the water phase.
Key Advantages
✅ Minimal odor
✅ High crop safety
✅ Safer for the operator
✅ Excellent environmental profile
✅ Meets the requirements for high-standard agricultural production
As the cultivation of fruits and vegetables continues to expand in Nigeria, a growing number of growers are choosing the higher safety profile offered by EW products.
