Selecting the right insecticide formulation is crucial for maximizing efficacy and ensuring cost-effectiveness in agricultural pest management. Diazinon, a potent organophosphate insecticide, is available in various formulations, with Emulsifiable Concentrates (EC) and Water Dispersible Granules (WDG) being among the most common. As a leading manufacturer and supplier of Diazinon in China, we aim to equip our clients with the knowledge to make informed purchasing decisions. This article compares Diazinon EC and WDG formulations, highlighting their respective strengths and ideal applications.

Diazinon, with its CAS number 333-41-5, is a highly effective insecticide known for its broad-spectrum activity against chewing and sucking insects and mites. The technical grade (95% TC) is the base ingredient, which is then processed into various user-friendly formulations.

Diazinon Emulsifiable Concentrate (EC):
EC formulations contain the active ingredient dissolved in an organic solvent, along with emulsifiers. When mixed with water, they form a stable emulsion, allowing for easy spraying and good coverage on plant foliage. The solvent base often aids in the penetration of the active ingredient into the plant cuticle or insect exoskeleton. This characteristic makes EC formulations particularly effective for foliar applications where rapid knockdown of pests is desired. However, the use of organic solvents can sometimes lead to phytotoxicity on sensitive crops under certain environmental conditions. When you choose to buy Diazinon EC, you are opting for a formulation that typically offers excellent wetting and spreading properties.

Diazinon Water Dispersible Granule (WDG):
WDG formulations are solid, granular products that readily disperse in water to form a suspension. They offer significant advantages in terms of handling safety and environmental impact. WDGs produce less dust compared to wettable powders, reducing applicator exposure. They are also generally stable in storage and easier to measure and mix. For applications where fine particle size and good suspension are important, or where minimizing solvent load is a priority, WDG formulations are an excellent choice. If you are looking to purchase Diazinon for applications requiring ease of handling and reduced dust, Diazinon WDG is a practical selection.

Key Differences and Considerations for Purchase:

  • Form: ECs are liquids; WDGs are solids (granules).
  • Mixing: ECs form emulsions; WDGs form suspensions.
  • Handling Safety: WDGs generally offer lower dust exposure risks.
  • Penetration: ECs may offer better penetration due to solvents.
  • Phytotoxicity: ECs can sometimes cause phytotoxicity on sensitive crops.
  • Storage: Both can be stable, but WDGs avoid solvent evaporation issues.
