Bordeaux Mixture |
|
The fungicidal effects of copper compound
have been known for many years since the important discovery of ‘Bordeaux
Mixture’ in France in 1887. The mixture of copper Sulphate and
Calcium Hydroxide is a good non-systemic fungicide capable of controlling
fungal diseases of Cardamom, Coffee, Rubber, Vegetables etc. This
copper compound with lime give a protective barrier on the plant surface,
there by preventing fungi from entering the plant host. The copper
ions react with the sulphur containing ligands in the enzyme of the
plant and inhibit the metabolism of the fungus. This effect has many
sites of attack so the fungi rarely build a resistance to copper based
fungicide. |
The quality and effectiveness of Bordeaux mixture
depends on the purity of copper Sulphate and lime and also on the
method of preparation. It is tricky and more tedious for a common
farmer. Moreover the Bordeaux mixture deteriorate on keeping and has
to be prepared fresh every time. In order to overcome these hurdles,
Biota Agro Solutions developed a ready to use Bordeaux mixture in
the form of a micro fine powder having all the properties of the conventional
Bordeaux mixture. This tailor made product having the brand name “Blue
Bordo” is an excellent protective fungicide. |

Cuprous Chloride |
|
Cuprous chloride is a stable compound of
univalent copper. It is having the chemical formula Cucl. This white
crystalline solid is highly soluble in water. Cucl is very sensitive
to heat and light. It can turn into yellow followed by reddish brown
cuprous oxide in presence of moisture. |
Commercially Cucl is manufactured by the reduction
of Cupric Salts. The product has the following specifications. |
