Choosing a product that has the ability to give both rapid uptake and long-lasting action helps to reduce costs versus cheaper quick acting products that require several repeat applications. Ensuring that a crops manganese demand is continually met reduces the likelihood of plant stress and likely yield loss.
|Maintenance application: apply as soon as there is sufficient foliage to absorb the sprayMaintenance application: apply when spring growth starts, up to GS31Deficiency application: apply when spring growth starts up to GS31|
|Apply prior to dormancyMaintenance application: at onset of rapid growthDeficiency application: at onset of rapid growth|
|Potatoes||When crop meets in the rows|
|If deficiency symptoms persist, repeat 7-10 days after flowering at 1.5 l/ha.Continue applications if deficiency persists|
|Sugar beet||4-6 leaf stage|
|Peas and Beans||10-15 cm high|
|If deficiency symptoms persist, repeat 7-10 days after flowering at 1.5 l/ha|
|Vegetables||4-6 leaf stage|
Omex trials have shown that the addition of efficient adjuvants to the spray solution, such as Omex NA13, significantly improves leaf coverage and uptake. This may not be necessary in multi-way tank mixes with crop protection chemicals, but we recommend that an adjuvant should always be used when Manganese treatments are applied alone.
Add Omex NA13 at 0.1% of the spray solution (e.g. 200 ml in 200 litres of water) to improve uptake.
Full tank mixing guidelines for SuperMn are available on the Omex web site.
Omex Super Mn is an inorganic liquid formulation containing (w/v) Nitrogen 3.0%, Manganese 11.5%, Magnesium (MgO) 2.4% and Sulphur (SO3) 12.5%
