Question
Hi,somebody told me that cow's urine is very effective for spraying on apple trees.can you tell me what contains the cow's urine and is it useful for preventing diseases from apple.

Answer
Dear Vivek, I was going to tell you that the only thing that cow urine would do would be that it would be a good fertilizer with nitrogen source.  Then I found that if you mix it with clay and cow dung, you can use it to seal wounds in the tree and it will keep out insects.  I also found this recipe for a fertilizer and insect repellent with cow urine in it.

Panchakavya:
Ingredients ?
Cow dung 5 kg
Cow urine 5 liters
Curd 2 liters (fermented for 15 days)
Ghee 0.5-1 liter
Jaggery 1 kg or Sugarcane juice 2 ?3 liters
Tender Coconut water 2 ?3 liters
Well ripened Banana (Poovan variety) 12
Yeast 50-100 gm or toddy 2 liters
Method of Preparation:

5 kg of cow dung is to be mixed with 5 liters of cow urine, sufficient quantity of water is also added and kept in mud pot or plastic drum and the mixture is stirred clockwise and anticlockwise (50 times each) every day.
On the 16th day, following ingredients are added.
Curd fermented for 15 days, milk 2 liters, Ghee 0.5-1 liter, Jaggery 1 kg or sugarcane juice 2-3 liters, Tender coconut 2-3, Poovan banana and yeast 50 gm or toddy 2 liters. This mixture is kept for 7 days. On the 22nd day, Panchakavya will be ready for use. This can be used for 6 months. (Panchakavya has to be stirred well every day until use)
Note: 2kg of cow dung is mixed with 0.5-1 liter of Ghee and is kept for 15 days which will facilitate the decomposing of ghee
Depending upon the growth of crops, the solution is sprayed once in 7 ?10 days by which the plant growth gets enhanced. Following are the effects of the solution,
Rectifies the micro nutrient deficiency
Acts as growth promoter
Acts as pest repellent
Provides immunity power to crops
Method of Application:
For short duration crops, it is sprayed twice ?before and after flowering
For flowering plants, it is sprayed once.
The solution can also be used for seeds and seedling treatment.
Spraying duration for Fruit Trees
I time ?one month before flowering
II time ?15 days after flowering
III time ?fruit attains pea size
IV time ?After harvesting, it is applied to all fruit trees once.
The solution is sprayed twice or thrice for each crop. For 1 liters of water, 25-30 ml of Panchakavya is mixed and sprayed.

I hope this information is useful to you, but let me know if you have more questions.  Melissa
