B-Green® contains the insect parasitic nematode Heterorhabditis bacteriophora which guarantees a fast and efficient biological control of white grubs in the soil. The most commonly occurring beetle larvae pest is Phyllopertha horticola (the garden chafer). It causes a lot of damage in grass fields and lawns. Heterorhabditis bacteriophora is able to rapidly and efficiently control the larvae of the garden chafer. Furthermore it is also an ideal controller for other beetle species such as the vine weevil (Otiorhynchus sulcatus). When the nematodes are introduced in the soil, they actively search for white grubs that are present in the root zone. The nematodes penetrate these larvae through natural body openings or directly through the body wall. Once the larva is penetrated, bacteria that live in symbiosis with the nematodes are released. These bacteria transform host tissue into products which can be easily absorbed by the nematodes. The nematodes multiply in the grub and when this decomposes, the new generation of useful nematodes, looking for new victims, disperses.
