Agrichemical products play a key role in increasing crop yields, protecting plants from pests and diseases, and ensuring overall agricultural productivity. The effectiveness of these agrochemicals depends not only on the active ingredient but also on the type of formulation.
The type of formulation determines the effectiveness and efficiency of the product, as well as its compatibility with other inputs and application methods. Several factors should be considered when selecting the type of formulation for an agrochemical product. These factors include the physical properties and toxicity of the technical material, target crop, target pest or disease, desired mode of action, application method, environmental considerations, etc.
Types of Formulations
Agrichemicals come in many formulation types, each with its unique properties. The three main categories are liquid preparations (emulsifiable concentrates, solutions and suspensions), solid preparations (powders, granules and tablets) and gaseous preparations (fumigants). The choice of formulation depends on factors such as the nature of the active ingredient, the target pest or disease, the method of application, environmental considerations and economic factors.
Physical properties of technical materials
When considering the physical properties of an active ingredient in agrochemical products, there are several factors to take into account when choosing the formulation type:
Physical property: Evaluate the physical property, solid or liquid. Generally, solid materials (melting point ≥80℃) are more likely to be produced for solid formulation, and liquid materials or low melting point materials (<80℃) are more suitable for liquid formulation. For example, in Propiconazole, a liquid technical product, the popular formulation type is EC (emulsifiable concentrate).
Solubility: Determine the solubility of the active ingredient in water or other solvents. This will help determine whether a liquid or solid formulation is more suitable. For example, water-soluble active ingredients may be better suited for liquid formulations, such as Proapamocarb HCl.

Stability: Assess the stability of the active ingredient under different conditions, such as temperature, light, and pH. Some active ingredients may degrade or lose effectiveness when exposed to certain conditions, which can influence the choice of formulation type.
Volatility: Consider the volatility of the active ingredient, which refers to its tendency to evaporate. Highly volatile active ingredients may require specific formulation types to minimize losses during application and ensure effective coverage.
Compatibility: Consider the compatibility of the active ingredient with different formulation types. Some active ingredients may have specific requirements or limitations when it comes to formulation. Ensure that the chosen formulation type is compatible with the active ingredient to maintain its efficacy.
Target Crop
Different crops may have specific requirements or sensitivities to certain formulation types. Consider the compatibility of the formulation with the target crop to ensure effective and safe application. For example, as seed treatment, metalaxyl-m (or Mefenoxam) is likely to be formulated to flowable concentrate for seed treatment (FS) or emulsion for seed treatment (ES), metalaxyl Technnical to powder for dry seed treatment (DS).

Pest or Disease
The type of pest or disease being targeted can influence the choice of formulation. Some pests may require specific formulations for effective control, while others may be more effectively managed with different types.
Mode of Action and Application Method
Consider the desired mode of action for the agrochemical product. Some formulations may provide systemic control, while others may act on contact. Choose a formulation that aligns with the intended mode of action. For example, fentin acetate, to skill snail by contacting, is generally formulated as WP.
The chosen formulation should be compatible with the intended application method. For example, liquid formulations may be suitable for spraying, while granular formulations may be more appropriate for soil incorporation.

Toxicity and Ecotoxicity Considerations
Assess the toxicity of the active ingredient to humans, animals, and the environment. Choose formulation types that minimize exposure and potential risks. For example, dust formulations may pose inhalation risks, while liquid formulations may have different risks associated with handling and application.
