Model application of Beauveria brongniartii products: Propagule types tested in pot and field trials


Abstract: A machine-compatible solution for the sustainable control of white grubs on steep slopes is in sight. The spiked injectors of the MMexit machine from the company Terratec GmbH (Bings/Austria) not only allows easy manoeuvring on steep slopes, but also the even injection of fungal dispersion formulations into the soil. Inoculative application of selected dispersion formulations of Beauveria brongniartii resulted in successful colonisation of the soil by the entomopathogen. In addition, pot experiments demonstrated that four B. brongniartii dispersion formulations showed excellent persistence and as such will be recommended in the future for specific use in white grub control.
