Turf

About

Used for lawns and sports fields, such as stadiums, golf courses, horse-racing tracks, athletic grounds, cricket pitches and football fields, turf provides the perfect base for a wide variety of sporting grounds around the world. It is also prized as a ground cover for recreational purposes such as green urban areas and private gardens.

Symptoms: Dead turf or lawn, which are often torn up by animals searching for the grubs.

What are grubs? Grubs are the larval stage of beetles, weevils, etc. that feed on turf or grass roots.

Controls: Nematodes are the most common biological control product used in turf care to concur pest species. It is important to match the correct nematode species to the pest.

Application Method: Typically applied by a Hose End Sprayer and a garden hose.

When to Apply Nematodes?

White Grubs (ON, QC) - Apply every year between end of August to the beginning of September when grubs are close to the top of the soil.

White Grubs (BC) - Apply every year between mid-July to early August when grubs are close to the top of the soil.

Crane Flies - Apply 2-3wks after the adults are visible on lawns where they are laying eggs. In most situations this would be in late July, August or early fall.

How to Apply Nematodes?

  • Use the product immediately or store at 2-6C (use product before best before date on package)
  • When you're ready to use the product, remove the packets from the box and let sit at room temperature for 30min.
  • After the 30min, stir package in 2L of water. Let soak for 5min.
    • Never leave a bucket unstirred for more than 30min. The nematodes will quickly settle to the bottom and suffocate.
  • When mixing the solution, apply immediately using a Hose End Sprayer with garden hose or spray equipment
    • Use as much water needed to apply the product to the area you would like to treat  
    • Spray the whole mix in one application
  • After applying the nematodes, a post-irrigation application should be done to wash the nematodes into the root zone
    • Keep the soil moist for a few weeks after application

Proper Conditions for Application

Soil Temperature: 14-33C or 57-91F

Nematodes are very susceptible to Ultraviolet Light (UV). Avoid spraying in direct sunlight.

Do not apply with chemicals. Nematodes are susceptible to various pesticides.

Pre-irrigation and post-irrigation for 2wks after application enhances the nematodes efficacy.

All filters should be removed on motorized sprayers, especially if finer than 0.3mm (50 mesh).

Mode of Action

Nematodes enter their pest and release symbiotic bacteria into the larvas body cavity. This bacteria converts the host tissue into a food source, on which the nematodes feed, develop, and reproduce on. The bacteria then kills the pest within a few days.
