Easy and simple way of Bordeaux mixture.

Bordeaux mixture is the oldest and popular fungicide to prevent fungal infections of many crops. This was introduced to India by British agriculture officer Leslie C Colman in 80’s. It is still used in all over the countries to prevent fungal and bacterial diseases. Although different types of fungicides came, but Bordeaux mixture is still retain its position today.
The unique character of this is economical, sticking capacity for long period and nutrition.
So far, no other fungal species has emerged where the Bordeaux solution was used. According to one study, when fungal filaments were examined by different states of the areca nut growing area, there all found the same species, with no new spices being developed. Research studies proved that this fungicide is also effective against many vegetable and fruit crops.
Few years back there is a very less number of farmers using this fungicide for their fruit and vegetable crops. But now many farmers are using this to protect their crops.
In areca nut farming, Bordeaux mixture is boon to the farmers. It is called the effective precautionary fungicide in almost all horticulture crops. The recommended dose of Bordeaux mixture is 1% .Studies are conducted in many research institutes, for different crops.
How to prepare Bordeaux mixture: main components required for the preparation is copper sulphate, calcium carbonate and water in 1:1:100 ratio. First of all to dissolve copper sulphate, take 1 Kg copper sulphate in cotton cloth and tie it. Then dip it in 10 liters of water. Now copper sulphate is available in powder form. There is no difference between crystal and powder.
Simultaneously you have to boil calcium carbonate shell in 10 liter of slight hot water. It will boil with in 10 minutes. If you are using powdered calcium hydroxide it is also no difference. For the convenience of farmers powder form copper sulphate and calcium carbonate are available in market. After the complete dilution, of copper sulphate and lime powder, you have to add these two ingredients simultaneously to 80 liters of fresh water stored in barrel.
All farmers note all preparations should be made in plastic containers. If you use metal container there is a chance of chemical reactions. Few years back farmers are adding some gum called RALA to stick this mixture to nuts in the time of raining. Now some spreaders are available. If we add spreaders its efficiency will increases. Now some good quality stickers are also available in the market. It is farmers’ willingness to add or not.
If it is added, the coverage is more. If gum is added , liquid mixture will stick quickly to the nuts and dry faster. When Spraying to tall trees gum and spreaders helps to accuracy sticking. Preparation of Bordeaux mixture is not a complicated subject. Some experts say it is essential to make the solution status into Neutral pH. If it become neutral pH in this proportion, it is good.
Otherwise it will become slight alkaline (Around 9-10pH).It is not a issue. Some farmers use 1:1.5 kg CuSO4 and Calcium. They are also satisfied with their preparations. 1% mixture is universally proved preparation. Farmers do not fear about controversies on two components. Copper sulphate should not be added much because it is acidic. Spraying in warm climate and pre germination of fungal pathogen, Bordeaux mixture helps to prevent disease more efficiently.
