    Comparative trials on the effects of two fungicides on a predatory mite in the laboratory and in the field (2000)

    Notes: Abstract Both laboratory tests with the open glass plate method of Louis & Ufer (1995) and a field study in a vineyard were carried out to test the side effects of the two fungicides, Dithane Ultra WG75 and Polyram Combi WG70, on the predatory mite Typhlodromus pyriScheuten (Acarina: Phytoseiidae). The effects of both fungicides in the residual contact test in the laboratory were more pronounced than the actual effects obtained in the field even after multiple application of the test products. The study results suggest, that for the selected test products the current laboratory guidelines correctly triggered the field test. Methodological problems of the laboratory test due to the repellent effect of the fungicides are discussed.

    Notes: 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.
