Last year, I had a problem with my lawn turning up with green patches. The patches were mostly around the edges of the lawn and had no specific shape. I have a sprinkler system on a timer and it was new sod. I saturated the lawn with 'Dursban'but it is coming back this year. Just recently I have noticed that there are flying pests above the lawn. Is there any conection, or is it something else? |
Dursban kills insects, cranefly larvae and cutworms in turfgrass areas so the application should have taken care of most of the pests. Adult cranefly's lay eggs in the soil under turf so when the eggs hatch the pupa (or leatherjackets) will have a source of food. If you see flying insects this time of year, that's probably what they are. The dark green areas around the edges of the lawn sound more like a cultural problem than an insect problem - perhaps caused by the leaching of fertilizer from adjacent flower beds? |
