As already described, the application of herbicide such as glyphosate would generally be required to provide a weed-free planting environment prior to planting and for an establishment period afterwards. Complete weed control is an essential precursor regardless of how it is achieved.
The modern non-residual herbicides dissipate in the environment very quickly, and since they would be only be used well before the first sign of flowering, it is not considered hazardous to the incoming bee population.
After planting and after the establishment period there ought to be no need for the use of any agricultural chemical inputs.
Provided the species is matched to the site, and the plantation is in full sun, it will be most unlikely that any fungal infestations will occur requiring the use of fungicides.
The ongoing use of herbicide will not be required provided grazing or slashing is provided to control grass growth and achieve general housekeeping objectives.
Insecticide will not be required as these plants are not subject to significant insect pest infestations.
There is no need to use miticides to control Varroa as we don’t have that pest in Australia despite a recent incursion in Queensland.
Above all else, there is a correlation between the use of agricultural chemicals and the death and decline of bee populations worldwide. The use of any agricultural chemicals around bees should be vigorously discouraged.
