Apis mellifera NeemAzalTM GreemaxTM mortality foraging activity brood development
2015/2/2
The effects of NeemAzalTM formulations: NeemAzalTM T/S (1% azadirachtin) and NeemAzalTM granules (1% azadirachtin) on honeybees, Apis mellifera L., were studied under semi-field conditions. Three plot...
Does treating faba bean seeds with chemical inducers simultaneously increase chocolate spot disease resistance and yield under field conditions?
Induced resistance growth parameters seed soaking seed yield Vicia faba
2010/10/29
The use of chemical inducers for the development of host resistance is an alternative approach to plant disease management and is assumed to be much more environmentally sound than traditional pestici...
