Bordeaux Mixture is produced by the neutralisation of Copper Sulphate with lime. This mixture has been invented by the French botanist Alexis-Millardet at the end of the nineteenth century. He used this fungicide on vineyards against Plasmopara viticola. The effectiveness of copper in agriculture is widely demonstrated and the use of Bordeaux Mixture has a wide application on many crops.
Manica SpA produces different formulations of Bordeaux Mixtures: concentrated suspension, wettable dispersible granules and wettable powder.
Studies have been conducted by the University of Trento (department of Industrial engineering) to detect the size and porosity of Bordeaux Mixture 20% WG. The high porosity, which characterizes the Manica’s microgranule, favours the entry of water allowing the complete and immediate dispersion of the mixture in the sprayer. Manica’s products have a high level of dispersivity (over 95%). There is no presence of powder in our formulation which guarantees a high level of safety for the worker during the manipulation.
Manica has developed an innovative Bordeaux Mixture Concentrated Suspension formulation. This product has a high level of stability, adhesiveness and resistance to wash off, thanks to the very fine particle size.
This special water-based formulation with neutral pH is very selective towards the most sensitive crops and by consequence the product can be mixed with the most common Plant Protection Products and others products (sulphur, insecticides and fertilizers).
