A List of Common Pests You May Encounter

Identifying Common Pests and Effective Management Strategies in Growcer Units

Overview 

The pests you may encounter in your Growcer unit can vary based on geographic region and the specific crops being grown. Any identified pest poses a potential risk, depending on the level of pest pressure, which can range from low to high. This article outlines some common pests and their signs, along with best practices for management. 

Common Pests 

  1. Thrips
    1. Description: Nearly microscopic, thrips are often identified by their signs rather than sighting the insects themselves. They can reproduce sexually or asexually, allowing populations to grow rapidly. 
    2. Signs: 
      1. Tiny, silvery spots (stippling) on leaves due to their sucking mouthparts. 
      2. Light yellow larvae may be visible on the dorsal side of affected leaves. 
      3. General slow plant growth and curled tips on new leaves. 
    3. Risk: Thrips can act as disease vectors by transferring pathogens while feeding. 
  2. Aphids
    1. Description: Larger than thrips, aphids are easily visible and come in various colors. They often cluster along stems and on the dorsal side of new leaves. 
    2. Signs: 
      1. Characteristic sticky structures (cornicles) on their backs. 
      2. Small shiny patches on leaves from honeydew, a waste product. 
    3. Risk: If not addressed quickly, aphids can reproduce rapidly, transforming into winged forms to infest new plants. They also serve as disease vectors. 
  3. Fungus Gnats
    1. Description: Adult fungus gnats resemble houseflies or mosquitos but have a slower flight. They do not harm plants as adults. 
    2. Signs: 
      1. The larvae are pale, semi-transparent with shiny black heads and about 6 mm long. 
      2. Signs of infestation include slow or stalled plant growth, discoloration, and loss of foliage. 
    3. Risk: Larvae feed on plant roots, which can lead to significant damage. 
  4. Whiteflies
    1. Description: Small, white moth-like insects visible to the naked eye, often found on the dorsal side of older leaves. 
    2. Signs: 
      1. Honeydew production similar to aphids. 
      2. Dry leaves, yellowing, tiny white spots, and underperforming new shoots. 
    3. Risk: Both adult and nymph stages can harm plants. 
  5. Spider Mites
    1. Description: Extremely small arachnids, less than 1 mm in size, that can infest nearly any plant. 
    2. Signs: 
      1. Early signs include yellow or white speckling (stippling) on leaves. 
      2. Presence of tiny webs along leaf margins, which protect their offspring. 
    3. Risk: As spider mite populations grow, they can lead to leaf shriveling and plant decline. 

Best Practices for Pest Management 

To effectively manage pest populations in your Growcer unit, adhere to the following best horticultural practices: 

  1. Regular Inspections: Allocate sufficient time for routine inspections of crops and the Growcer unit to catch potential pest issues early. 
  2. Monitor Sticky Traps: Check sticky trap cards regularly to detect and address any pest problems promptly. 
  3. Verify Air Curtain Functionality: Ensure the air curtain is functioning properly to maintain optimal environmental conditions. 
  4. Pest-Free Outdoor Clothing: Ensure that outdoor clothing and shoes are pest-free before entering growing areas to prevent introducing pests. 
  5. Provide Detailed Plant Health Information: When communicating with Growcer about plant health concerns, provide comprehensive details, including descriptions of affected plants and any visible symptoms like discoloration or spotting. 

Conclusion 

Understanding common pests and implementing proactive management strategies is key to maintaining a healthy Growcer unit. Regular monitoring and prompt action can significantly reduce the risk of pest-related damage. For further assistance, please consult help@thegrowcer.ca
