Contact Insecticides vs. Systemic Insecticides: Differences, Examples, and Selection Methods
The main difference between contact insecticides and systemic insecticides lies in how pests come into contact with the active ingredient and whether the pesticide can be absorbed by the plant and transported within its tissues. Contact insecticides primarily work through direct contact between t...Read more -
Contact vs. Systemic Fungicides: What Is the Difference Between Contact and Systemic Fungicides?
Contact fungicides and systemic fungicides are two important product types in agricultural disease management. The main difference between them lies in how the active ingredient is distributed on the plant surface and within plant tissues after application, as well as which parts of the plant the...Read more -
How does spray droplet size affect pesticide coverage?
When applying pesticides, droplet size directly influences the movement of the spray in the air, its ability to reach the target surface, and the resulting coverage and deposition. Smaller spray droplets generally offer greater potential coverage, but are also more susceptible to wind and evapora...Read more -
Adjuvant vs. Surfactant: What Is the Difference Between Pesticide Adjuvants and Surfactants?
Adjuvants and surfactants often appear together in pesticide application, but they are not the same concept. An adjuvant is a broader functional category, while a surfactant is a specific type of substance within that category that alters the surface tension or interfacial properties of a liquid....Read more -
How Do Pesticide Formulations and Formulations Affect Rainfastness?
Two pesticides may contain the same active ingredient at the same concentration, but they may perform differently when exposed to rain after application. One key reason is that they use different formulation systems. A pesticide’s rainfastness depends not only on the active ingredient but a...Read more -
How Does Water Quality Affect Pesticide Performance?
Water quality affects pesticide performance because water is not only the medium for diluting and delivering pesticides, but the mineral ions, pH, dissolved salts, and suspended impurities it contains can also interact with the active ingredients or formulation adjuvants. These effects are primar...Read more -
What Are the Differences Between Wettability, Suspension Rate, and Dispersibility in Pesticide Formulations?
Wettability, dispersibility, and suspension rate are all important physical indicators for evaluating the water-mixing performance of pesticide formulations, but they do not describe the same process. The entire process can be understood as: Formulation comes into contact with water → Is wetted b...Read more -
What Causes Crystal Growth in SC Pesticide Formulations?
Crystal growth is one of the important physical stability challenges that can occur in SC pesticide formulations during storage. Unlike sedimentation, where suspended particles simply move downward under gravity, crystal growth changes the physical structure of the active ingredient particles the...Read more -
What Causes Sedimentation in SC Pesticides?
Sedimentation occurs in SC pesticides because the active ingredient is present as solid particles suspended in a liquid phase rather than completely dissolved. Gravity naturally drives those particles downward over time. However, the rate and structure of settling depend on much more than gravity...Read more -
Meet SunAgro at Growtech Antalya 2026
SunAgro will participate in Growtech Antalya 2026 from November 24–27, 2026, at the ANFAŞ Expo Center in Antalya, Türkiye. We welcome agrochemical importers, distributors, registration companies, and agricultural partners to visit us at Booth H6-A120. Explore Crop Protection Opportunities At the ...Read more -
How Particle Size Affects SC Pesticide Performance
Particle size is one of the key physical variables in a suspension concentrate, or SC, because the active ingredient remains as fine solid particles rather than being completely dissolved in the liquid phase. The size and distribution of those particles can influence sedimentation, suspension sta...Read more -
What Is FS in Pesticides? Seed Treatment Formulation Explained
FS stands for Flowable Concentrate for Seed Treatment. It is a liquid pesticide formulation designed specifically for treating seed before planting. In an FS formulation, the active ingredient is commonly present as fine solid particles dispersed in a liquid continuous phase rather than completel...Read more
