General remarks concerning biological control in turf and lawn

	Before starting application of natural enemies, the lawn needs to be free of harmful pesticide residues.
	Fertilizers and iron sulphate do not influence the nematodes' action, if applied in 'normal quantities'.
	In case of doubt concerning the side effects of chemicals contact your Biobest technical representative.
	Before spraying the nematodes with a (field) sprinkler, carefully follow the user's instructions (thoroughly rinse the tank in which the nematodes will be poured, etc.).
	The garden chafer (Phyllopertha horticola) are effectively controlled by B-Green. The action against the cockchafer and the summer chafer is not effective enough. Please contact Biobest N.V. if you are not sure which type of beetle you are dealing with.
