| A common consequence of misapplied herbicides (spray), misapplied fertilisers (mostly over-fertilisation) and high precipitation following the application of fertilisers (leaching).
Curative measures
If herbicides are applied in vicinity of Christmas tree-plantations - precise spraying required (no wind, precise dosage), sparing fertilisation, never during rain.
