PEST CONTROL
By Derrick Donnison- Morgan

This article writes about the several methods which can be used in Gardens for pest control,
Starting with Cultural control, handpick all diseased leaves from plants, keep secateurs clean etc. Let me add that heavy machinery, used to up root diseased trees, should be disinfected when moved to another area.
Biological control, attract birds to the garden, understand which insects help by eating aphids etc.
Chemical control only if necessary, disruption of insect communications and so on.
Since it is 20 odd years since this article was written there must have been some more discoveries on how to deal with pests in the garden.
The Palm weevil, Rhynchophorus ferrugineus, not mentioned in this article, was first reported in Greece in 2004. The photos of the weevil were taken in Sparta where many of the tall palm trees were devastated by this pest despite the various attempts to save them.
The photo of the tall Palm tree wrapped in protective netting was taken in the Royal Botanic Garden Madrid in 2018, This year we saw the tree in an unwrapped state and looking in perfect condition.
I can only assume that a way has been discovered to deal with this horrible pest.
