LUQSAMAG-S is a soluble liquid magnesium solution containing trace elements, which acts both preventatively and curatively against deficiencies caused by a lack of magnesium, sulphur and the trace elements present in this formulation.
Magnesium is a component of the chlorophyll molecule and plays a key role in photosynthesis and the formation of other pigments; it also activates many of the enzymes involved in carbohydrate and protein metabolism.
Sulphur is a component of vitamins, amino acids such as cysteine and methionine, proteins, coenzymes and glycosides.
Leaf application: 150–200 cm3/hL of water.
Depending on the crop’s requirements or the severity of the deficiency, 2–3 treatments may be required, spaced approximately 20 days apart.
Application by fertigation:
Small trees and low-growing plants: 20–30 cm3 per plant.
Young trees: 30–75 cm3 per tree.
Mature trees: 75–125 cm3 per tree.
When applied as a foliar spray, it can be mixed with all commonly used fertilisers and plant protection products, except those with a strongly alkaline reaction.
Avoid applying the product during the hottest part of the day.
Thoroughly wet all the foliage.
