- the active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms prepared from these formulations in a mixture with synergists.
- Synergists are compounds through which the action of the active ingredients is increased without the added synergist itself having to be active.
- Formulations used directly contain between 10 " 7" and 5 percent by weight, preferably between 10 ⁇ 4 and 1 percent by weight of active ingredient.
- Formulations that are used only after further dilution contain 1 to 95 percent by weight, preferably 5 to 90 percent by weight of active ingredient.
- the preparation and use of the active compounds according to the invention can be seen from the examples below.
- Extracts were dried with Na 2 S0 4 and evaporated.
- the mixture was poured onto 50 ml of saturated bicarbonate solution, the organic phase was separated off and extracted three more times with ether. The combined extracts were dried with sodium sulfate and evaporated in vacuo on a rotary evaporator. The residue was stirred with a little ether and thereby crystallized.
- the starting materials for the preparation of the compounds described are ultimately the avermectin fermentation products specified above.
- Other avermectin derivatives with alpha-branched alkyl or alkenyl groups in the 25-position, denoted R2 in formula (I), have been described in EP-A-214 731, EP-A-276 131 and EP-A-276 103.
- Other starting substances have a 22-23 single bond. Their production by reduction of fermentation products is described in US-A-4, 199,569
- Test animals Lucilia cuprina larvae (1st-3rd stage)
- the active ingredient solution is diluted with water to the desired concentration.
- test tube containing approx. 1 cm 3 horse meat and 0.5 ml of the active ingredient preparation to be tested. The effectiveness of the active substance preparation is determined after 24 and 48 hours.
- the test tubes are transferred to beakers with a sand-covered bottom. After a further 2 days, the test tubes are removed and the dolls are counted.
- the effect of the preparation of active substance is assessed according to the number of flies hatched after 1.5 times the development time of an untreated control. 100% means that no flies have hatched; 0% means that all flies hatched normally.
- Test animals adult sucked females of Boophilus microplus (strain
- the active ingredient solution is diluted with water to the desired concentration.
- 100% means that all ticks have been killed or no eggs have been laid; 0% means that no ticks have been killed or that, compared to the control, normal egg laying has taken place.
- the compound according to Example II shows an effectiveness of 100% in an exemplary concentration of 1 ppm.
- Test animals adult Musca domestica, strain WHO (N) (sensitive)
- the active ingredient solution is diluted with water to the desired concentration.
- the effectiveness of the active substance preparation is determined after 1, 3, 5 and 24 hours. 100% means that all flies hatched have been killed; 0% means that no flies have been killed.
