Irregular patches of yellow grass that can reach up to a meter in diameter and sometimes even more. Lawn torn up by skunks that like to feed on the grubs.
Period when symptoms appear
April-May and late August to early September.
White grubs are the larvae of the June beetle.
The grass is no longer fastened to the soil and can be pulled out easily. Presence of white, "C"-shaped larvae (1 to 5 cm long).
- Increase the mowing length (6-8 cm)
- Seed the damaged patches.
Apply nematodes (microscopic worms that attack white grubs) in mid-August when the soil temperature is adequate. After applying the nematodes, water generously to allow them to penetrate the soil.
