Greenhouse Whitefly Control

Whitefly (Trialeurodes vaporariorum) is a common pest of both vegetable and ornamental crops. Its wide range of host plants, including eggplant, cucumber, tomato, rose and gerbera, makes it a persistent problem in horticulture. Originally from tropical and subtropical climates, the whitefly has adapted to greenhouse environments worldwide. To control whiteflies, you can use chemical and biological products from Royal Brinkman Canada. 
 

How to Recognize Whiteflies? 

Whiteflies are small, white, moth-like insects that typically hide on the undersides of leaves. These pests feed on plant sap, leading to visible signs of infestation. Common symptoms include:

  • Sticky honeydew on leaves
  • Yellowing and wilting of foliage
  • Visible adult whiteflies fluttering when the plant is disturbed
  • Sooty mold on leaves due to honeydew deposits


You can differentiate between species such as the greenhouse whitefly (Trialeurodes vaporariorum) and the tobacco whitefly (Bemisia tabaci) based on size and color differences.
 

Organic Whitefly Control

To manage whiteflies organically in greenhouse ornamentals, using natural enemies is essential. This sustainable approach minimizes chemical interventions while effectively controlling pest populations. Parasitic wasps and predatory mites are particularly effective in targeting whitefly larvae and non-mobile stages, reducing the spread of this pest. By integrating multiple biological controls, you can ensure comprehensive pest management and promote healthy crop growth. Combine biological control with proper hygiene for optimal results. Key natural enemies are:
