CROP CRACK - 13.01.07
By WENDY FEARON

The persistent rain and stormy conditions over the Christmas period
have severely hampered attempts to harvest the remainder of the
potato crop and ground conditions have left it impossible to spray
winter cereals. Many crops are beginning to show signs of stress.
Growers should be making the best of this quieter time to assess the
performance of last season’s crops and plan for the incoming season.
Fields which are going to be cropped early should be identified and
an up to date soil analysis carried out. Plan seed supplies and
order it soon to ensure the required variety is available.
Routine machinery maintenance should be carried out at this time of
year to prevent unnecessary breakdowns during the busy season.
WINTER CEREALS
Grass weeds can be controlled with herbicides containing IPU up to
early tillering and are therefore only effectively controlled by
spraying them in the autumn or early winter. Likewise broad-leaved
weeds are best controlled when small along with any grass weeds
using autumn residual products such as ENCORE, AUTUMN KITE, or
PANTHER.
POTATOES
Check potatoes in storage regularly to ensure there is no excessive
spoilage occurring. The relatively mild conditions throughout the
autumn and winter will increase the risk of early sprouting in
ambient stores and will reduce potential storage times.
Sprouting can now be controlled in ware potatoes during storage
with a granular formulation of MSS CIPC 5G.Previosly it could only
be applied as a fog through a specialist machine hence restricting
its use to very large stores. This is an ideal product for smaller
storage facilities where fogging is not an option. Only clean mature
and disease free potatoes should be treated. CIPC 5G should be
applied when sprouts are more than 0.5mm on inspection during the
storage period. It will kill the growing points and further growth
will cease. Potatoes must be dry, cured and the skins set before
application. CIPC 5G must not be used on a seed crop.
HEDGEROW WEED CONTROL
January and February are the best time to control weeds around young
hedges and trees. Season long control of grassed and most
broad-leaved weeds is possible by applying Kerb Granules now.
MACHINERY MAINTENANCE
Agrochemicals and fertilizers are major variable inputs in growing
crops and the way they are applied has a great influence on their
efficacy.
It is essential therefore that the equipment used to apply them is
well maintained and accurate.
Sprayers should be calibrated regularly. One of the most
important areas of the sprayer is the nozzle. Nozzle output should
be measured to check that it is the same as the value in the
calibration chart for that type of nozzle. Nozzles with a variation
of more than 5% should be changed.
Money spent maintaining the sprayer is money well spent as a
properly calibrated sprayer will reduce wastage of agrochemicals and
will improve their performance.
Similarly fertilizer sowers should be calibrated and if possible get
a tray test carried out to check the spread pattern as striping in
crops is often caused by uneven fertilizer application, which again
wastes money.
I would like to take this opportunity to wish you all a very
prosperous new year! |
