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.
