Default Thrips tormenting me!

Can anyone help? This is the first year I've put in roses and have become
obsessed with them. All my good work seems to be being undone by massive
numbers of thrips! I've tried white oil, but the plants didn't look so happy
afterwards (and it didn't annhilate them as I had hoped). It was suggested
to me that I should just squash them with my fingers but that'd have me
working day and night to get them all. Any suggestions out there? I'm
despairing as I see my new rose buds eaten into by these predators!!

Default Thrips tormenting me!

You should be so lucky. They attack me as well as the roses.

Here are some simple organic tips for dealing with a wide range of pest
problems in the garden:

# Thrips are hard to control, although the onset of hot dry weather also
reduces their numbers considerably. Glue spray will work, as will garlic
spray: for every 100g of chopped garlic, soak in 2 tablespoons of
mineral oil overnight or longer, then add insecticidal soap, available
from good garden centres dissolved in 600mls of water. Before spraying
dilute by up to ten times in volume.

# Fruit fly and codling moth can both be effectively controlled by
rigorously collecting any fallen fruit and sealing it in heavy duty
black plastic to kill the larvae Chooks will eat any fruit....
and do the same job and lay eggs.

# Spray tiny green aphids with a strong blast of water or squash them on
the stem. If the infestation worsens, try glue spray, which clogs them
up and kills them effectively. Mix one cup of white flour with one cup
of boiling water and dilute with around 4 cups of cold water. Spray
heavily, repeating every week or so, and remember to clean your nozzles
and bottles to stop them clogging up too. Aphids are cyclical and their
first flush disappears before Christmas in most seasons.


# Aphids produce a sticky substance called honeydew which attracts small
ants and helps spread the aphids and their eggs. Grease bands around the
base of affected trees can help prevent their spread.





# Scale has a number of different manifestations and colours including
white waxy clusters, red scale on citrus and black scale on evergreens,
but all form clusters on the stems of plants and suck out the cells
beneath. Ants spread scale, so control them, and brush the infestations
off with your hands, nails or a wire brush.


# Slaters and earwigs enjoy hiding in dark corners, so trap them at
their own game with crumpled newspaper in plastic pots. Grease bands
will stop earwigs climbing rose bushes to eat the buds, and they're also
reputed to flock to saucers of oil, in which they drown.
