SPECIAL PROGRAMME FOR BIOLOGICAL COCKCHAFER GRUB CONTROL
nema-green® Maikäfer
Combination of beneficial Steinernema and Heterorhabditis nematodes against young larval stages
| 75 million nematodes • pack for 100 m² • 2 applications per year • programme over 2 consecutive years |
Short description
nema-green® Maikäfer is a specialist biological cockchafer grub control product. It contains 75 million living Steinernema and Heterorhabditis nematodes; one pack covers 100 m².
Cockchafer larvae develop over several years and become harder to control with age. The programme therefore has two precise applications: spring against L2 and late summer against newly hatched L1. The manufacturer recommends the full programme in two consecutive years.
Key properties
Specifically developed for cockchafer grubs;
Combines Steinernema and Heterorhabditis nematodes;
75 million nematodes per pack for 100 m²;
Key properties
Two complementary windows: April/May and August/September;
Targets more susceptible young L1 and L2 stages;
Two-year programme addressing successive larval cohorts.
Target pests and application period
| Target pest / stage | Recommended period and rate |
| Cockchafer / Melolontha melolontha – L2 | First treatment in April or May |
| Cockchafer / Melolontha melolontha – newly hatched L1 | Second treatment in August or September |
| Treatment programme | Carry out both applications in two consecutive years |
How do beneficial nematodes work?
Infective nematode stages search for a suitable soil host, enter it and release symbiotic bacteria. These multiply and kill the larva. Nematodes reproduce inside the dead host; new infective stages emerge and seek other susceptible larvae.
When is this product the right choice?
Choose nema-green® Maikäfer following confirmed cockchafer grub infestation. It is not a universal substitute for standard nema-green®; use it as a consistent programme, not a one-off reaction to widespread damage.
Preparation and application
Identify cockchafer grubs reliably. They are larger than many other grubs, but professional identification should guide product choice.
Plan the full programme: application 1 in April/May against L2; application 2 in August/September against newly hatched L1; repeat next year.
Check soil temperature and moisture. Treat when soil exceeds 12°C for at least four hours daily and is sufficiently moist.
Prepare the whole pack according to instructions and treat 100 m² evenly.
Irrigate afterwards to wash nematodes into soil and maintain the moisture required by current instructions.
Conditions for successful application
Soil above 12°C for at least 4 hours daily;
Moist soil before and after treatment;
Overcast, moist weather or evening application;
Complete, even treatment of 100 m² per pack;
Both treatment dates completed and programme repeated next year.
| Nematodes are living organisms. Success depends on rate, correct pest species, susceptible stage, soil temperature, moisture and UV protection. |

Frequently asked questions
Why two applications per year?
Spring treatment targets L2, late-summer treatment newly hatched L1, covering two susceptible developmental points.
Why does the programme last two years?
Cockchafers have a multi-year life cycle. Repetition targets further cohorts of young larvae.
Can standard nema-green® be used?
The products are not interchangeable alternatives. The cockchafer variant has its own composition and programme.
Is one application enough for severe damage?
The manufacturer recommends two treatments a year in two consecutive years. Shortening the programme may miss further susceptible stages.
| Important: check the rate, timing and aftercare against the current label. Do not use after the expiry date. |
