Wettable Powders

Types of Wettable Powders (WP) & Their Modes of Action

Wettable powders (WP) are dry, finely ground pesticide formulations that mix with water for application. They provide good residual control and are widely used in agriculture, pest control, and landscaping.

Insecticidal Wettable Powders

• Mode of Action: Targets the nervous system of insects, leading to paralysis and death.
• Examples on the Market:
  • Demon WP (Cypermethrin) – Controls ants, roaches, and other pests.
  • Tempo WP (Beta-Cyfluthrin) – Fast-acting for broad-spectrum insect control.
  • Sevin 85 WP (Carbaryl) – Used in agriculture and gardens.

Fungicidal Wettable Powders

• Mode of Action: Disrupts fungal cell membranes or inhibits spore germination to prevent plant diseases.
• Examples on the Market:
  • Dithane M-45 (Mancozeb) – Protects against fungal diseases in crops.
  • Captan 50 WP (Captan) – Used for fruits, vegetables, and ornamentals.
  • Sulfur WP (Sulfur-based) – Controls powdery mildew and other fungal issues.

Herbicidal Wettable Powders

• Mode of Action: Inhibits photosynthesis or disrupts plant growth to control weeds.
• Examples on the Market:
  • Princep 4L WP (Simazine) – Pre-emergent herbicide for grasses and broadleaf weeds.
  • Karmex WP (Diuron) – Used in industrial weed control.
  • Atrazine 90DF (Atrazine) – Controls broadleaf weeds in crops.

Bactericidal Wettable Powders

• Mode of Action: Inhibits bacterial growth and prevents plant diseases.
• Examples on the Market:
  • Kocide 3000 (Copper Hydroxide) – Used to control bacterial and fungal diseases.
  • Agri-Mycin 17 WP (Streptomycin Sulfate) – Controls fire blight in apples and pears.

Wettable powders provide long-lasting control but require constant agitation in the spray tank to prevent settling.
