Abstract The side effect of 10 insecticides, 5 fungicides and 5 herbicides on 24 different species of beneficial organisms was tested by members of the Working Group ‘Pesticides and Beneficial Organisms’ of the International Organization for Biological Control (IOBC), West Palaearctic Regional Section (WPRS). The tests were conducted by 32 members in 12 countries according to internationally approved guidelines. The microbial insecticides Bacillus thuringiensis var. kurstaki (Delfin), B. thuringiensis var. tenebrionis (Novodor) and Verticillium lecanii (Micro Germin), the fungicides cyproconazol (Alto), difenoconazol (Score), lecithin (Bioblatt Mehltau) and penconazol (Omnex), and the herbicides ethofumesat (Tramat), fluroxypyr (Starane), haloxyfop (Gallant), isoproturon (Arelon) and metamitron (Goltix) were harmless to nearly all the beneficial arthropods. The benzoylurea's teflubenzuron (Nomolt) and flufenoxuron (Cascade) affected predators such as anthocorids, earwigs, coccinellids and lacewings. The remaining preparations were more toxic and should therefore be further tested in semi-field and field experiments on relevant organisms. Most tested fungicides were toxic for the entomopathogenic fungi.
