Law’s, the independent
company supplying fertilisers and crop protection to the market,
is receiving considerable interest in their copper-based fungicide,
Wetcol 3 which is suitable for both conventional and organic potatoes.
“Potato planting has been well ahead of previous years and
growers understand the need to protect their investment right from
the start as soon as the crop starts to emerge. Already Smith periods
have been recorded in many parts of the UK and early spraying will
have started. Although there is a wide range of fungicides available,
there are very few that can be used on both conventional and organic
crops. Fully approved, Wetcol 3 is a copper-based fungicide registered
for use in potatoes as well as a wide range of vegetable and fruit
crops. It is a blend of purely naturally occurring ingredients including
copper as a tetracopper tricalcium sulphate and soluble calcium,
formulated as a stable dispersion. In addition to blight prevention,
the soluble calcium in Wetcol helps to reduce internal rust spot
in potatoes and can help skin finish,” explains Mark Law,
Managing Director of Law’s.
“Coverage of the potato foliage is essential for any protectant
fungicide and Wetcol has a modern up to date formulation that will
ensure good coverage. It contains its own naturally-based spreaders
and stickers which add to its effective coverage, whilst maintaining
its approval for use in organic farming. The product has a very
fine particle size of just 2 microns, resulting in better leaf coverage
and rainfastness, important in a showery weather or under irrigation
regimes,” reminds Mark.
“This fungicide has shown effective control against potato
blight, providing application and coverage is adequate. There is
no reason why conventional growers as well as organic growers shouldn’t
gain from its efficacy,” says Mr. Law.
“Both The Soil Association and Organic Farmers & Growers
permit the use of Wetcol 3 where need can be justified which is
easily proved with the recording of Smith periods. Furthermore,
there are no effective resistant potato varieties and blight can
severely reduce yield and quality within a few weeks of the initial
infection. Growers have little option if they are to grow a good
yielding and high quality crop,” says Mark.
“We would advise growers to get ahead of the game and apply
for use of Wetcol straight away. Obviously for conventional growers
Wetcol is fully approved and they can get on and protect their crop
with no further complications,” says Mark.
Wetcol is recommended in potatoes for the control of late blight.
It is applied at dose rates of 25-50 litres per hectare in 800 litres
of water, to ensure complete coverage of the crop canopy. It is
recommended as a first spray or as advised and repeated at 10-14
day intervals using the higher doses later in the season.
