Since it contains five items, it is named ET5.

Ingredients: (a) 100 ml organic vinegar, (b) 100 ml ET, (c) 100 gms jiggery, (d) 100 ml brandy, (e) 600 ml water, for a total of one liter.

Preparation:

• Mix all and let ferment for 7-10 days.

Usage: Use within 30 days. Spray 2-5 ml per liter of water, along with any of the growth promoters. In case of severe infection use 10 ml per liter of water.

Benefits:  Controls fungal bacterial, and powdery mildew diseases.

To prepare organic vinegar, use one of the following methods (taught to us by Dr. L. Narayana Reddy):  (a) Add 500 gms jiggery to 1 liter tender coconut and store in a container for a minimum of 15 days.  (b)  Mix 8 numbers rotten banana, 200 gms jiggery and a small quantity of water; bring it to a semisolid form.  Add water to make it two liters. Keep it for a minimum of 15 days. 

Vinegar may be kept for a long time.  With each passing day the quality improves due to fermentation.  The older it is, the more effective it will be in ET5 preparation.
