The small caterpillars of the Gooseberry Sawfly can soon
ruin a plant if not spotted and treated in good time. Small,
black-spotted green caterpillars - up to 2.5cm long get to work and can
strip a Gooseberry bush of leaves in just a few days. it can also attack
currants with the same devastating effect.
With around three generations in a year, the sawfly is
a serious pest, and unless close watch is kept, can be a very serious
problem.
As soon as the foliage breaks in early April, do
regular checks for this pest. If just a few are noticed, then they can
be picked off by hand. However, Provado is a good systemic insecticide
to use, or Bifenthrin can be used as a contact spray. |
