We are very satisfied with the product. After two applications within three weeks, we found no larvae in the soil. We now ensure sufficient soil moisture on the treated sports field so that the metarhizium fungus applied there can persist in the soil.
The products worked very well against garden leaf beetle larvae on the areas treated last year. I no longer have any problems there. This year I had to treat other areas and I can already see the first results: many “half-dead larvae” and the damaged grass is already growing well again.
