By monitoring the emergence of wasps from the eggs and then their ability to parasitise fresh supplies of eggs, the test investigates the eff e c t of the chemicals on the ‘beneficial capacity’ of Trichogramma rather than simply on its surv i v a l . The effect of FA S TAC Duo was compared with that of endosulfan. FA S TAC Duo had only a minor effect on the emergence of the parasites and on their beneficial c a p a c i t y, where endosulfan was highly toxic to the wasps. FA S TAC Duo can therefore be classified as harmless to preadult Tr i c h o g r a m m a . A five-year study along with other field trials data reveal no evidence that FA S TA C Duo t r e a t m e n t s had any long term adverse effects on any of the beneficial taxa studied. The major beneficial groups included parasitic wasps, and the import a n t p r e d a t o ry groups included ground beetle (C a r a b i d a e ), rove beetles (S t a p h y l i n i d a e ) a n d money spiders (Linyphiidae). G e n e r a l l y, the other insecticides used in the trials had more effect than FA S TAC on beneficial foliage dwelling art h r o p o d s . Aquatic Organisms Tests with the invertebrate zooplankter, D a p h n i a m a g n a , and the rainbow trout, O n c h o r h y n c h u s mykiss, in pristine water showed that, as expected, FA S TA CDuo has a high level of acute toxicity under l a b o r a t o ry conditions. This high toxicity under l a b o r a t o ry conditions is common to all pyrethroid insecticides and indicates potential hazards. Further studies were set up to find out how serious these potential hazards might be in practice and to investigate the likelihood of long term problems or of any sub-lethal effects. Both the fish and Daphnia test showed there were no significant chronic or sub-lethal toxic effects from prolonged exposure to FA S TAC Duo. The limited and transient nature of FA S TAC Duo’s e ffects on invertebrate populations when used under commercial conditions contrast with its high level of acute toxicity in the laboratory. Analysis of the pond and ditch water during the small plot experiments and commercial scale aerial spraying trials showed that concentrations of FA S TAC Duo in the water were always lower than early predictions had suggested. The hydrophobic nature of alpha-cypermethrin and its very low water s o l u b i l i t y, coupled with the very low application rates, results in low concentrations of FA S TAC Duo in the body of the water. In addition, alphac y p e rmethrin molecules are adsorbed strongly onto the surface of organic matter in ponds and w a t e rways. This, and natural degradation, tends to lower the concentration in the water even furt h e r. S u m m a ry Environmentally FA S TA C Duo has shown that despite its high level of activity against pests, when used as recommended, it generally has little effect on non target species. 6
Insecticide Resistance For insecticide resistance management FA S TAC Duo is a Group 3A Insecticide. Some naturally occurring insect biotypes resistant to FA S TAC Duo and other Group 3A insecticides may exist through norm a l genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if FA S TAC Duo or other Group 3A insecticides are used repeatedly. The effectiveness of FA S TAC Duo on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, BASF Australia Ltd accepts no liability for any losses that may result from the failure of FA S TA CD u o to control resistant insects. FA S TA C D u o may be subject to specific resistance management strategies. For f u rther information, contact your local supplier, BASF Australia Ltd representative or local agricultural department agronomist. In NSW and Qld, application of this product to Helicoverpa arm i g e r a l a rvae longer than 5 mm may not only be ineffective but it may increase the level of synthetic pyrethroid resistance. This product should NOT be used to treat infestations that were not controlled by an earlier application of it or another synthetic pyrethroid. Infestations not controlled by this product should be treated with an insecticide from another chemical group. Application of this product with an insecticide from another chemical group such as NUDRIN will assist with the management of synthetic pyrethroid resistant Helicoverpa arm i g e r a . 7
