When can I apply Nemasys Chafer Grub Killer?
Nemasys Chafer Grub Killer should be applied when the soil temperature is at a minimum of 12°C (54°F) and the chafer grubs are at the correct stage in their lifecycle. This will be August and September. Do not apply too late, since the grubs start to move down deeper in the soil and become inactive until the following spring. However, as this move downwards is temperature dependent, in some years it may still be all right to apply later. As long as the grubs are near the surface and the soil temperature is above 12°C (54°F) nematodes can still be applied.
