An excellent method to ward off wild animals from crops

FARMERS IN India and abroad face serious threats from pests, natural
calamities, thefts, damages by animals and other types of crop losses,
resulting in lower yields.
Most often, none of the steps taken to counter the problems are
foolproof.
“More pronounced damage gets caused by wild animals in lands adjacent
to forest areas during summer, due to food and water shortage in the
forests.
“Farmers and officials plead helplessness in solving this perennial
problem, and say they only try to drive the wild animals away
manually,” says Dr. Narahari, former Professor and Head, Poultry
Science, Tamil Nadu Veterinary and Animal Sciences University,
Chennai.

New methods
Though scientists constantly search for new methods of crop
management, to reduce losses to farmers, the damage by wild animals
such as deer, elephants, and wild boars continue.
“For example, in North America, particularly the U.S., crop damage due
to wild deer is a common occurrence. Large herds of these animals
frequently cross the roads during nights, causing many accidents and
enter into human habitations and damage home gardens and field crops.

Hatchery waste
“Though farmers tried several methods, the problem continued.
Interestingly, some workers in chick hatcheries noticed that the deer
herds do not come near the places where they dispose their hatchery
waste; which contains a lot of unhatched eggs,” says Dr. Narahari.
By observing this, some hatchery workers started spraying the egg
contents mixed with water, on their home gardens and noticed that the
deer do not come near the plants (sprayed with egg contents), probably
due to the pungent odour emitted by the raw egg contents when exposed
to the air.

Successful results
After noticing these successful results, agricultural scientists
started refining this technique for larger application and succeeded
in minimising the attacks of the animals on field crops
“In India we read reports that wild animal such as elephants and bison
venturing into the fields, destroying the crops.
“If we adopt this idea, we may be able to protect our crops from
damage. It will be worthwhile for our farmers to try this method and
give us the feedback. As of now I don’t think any person in India is
practising this,” he says.

Several problems
With today’s agriculture facing many problems, a good crop yield with
minimal expenditure is the need of the hour, and farmers who want to
try this method need not spend much.
Giving details on how to use this technology Dr, Narahari explains:
Use egg contents (both albumen and yolk), preferably from broken,
damaged, old, liquefied, unhatched or even ordinary table eggs,
(unhatched eggs from hatcheries are not only cheaper, but also emit
more pungent smell, disliked by herbivorous animals.)

Fertilizer
Break open the egg shell and pour the contents into a bucket or
barrel. Mix yolk and albumen together. Hand-crush the leftover shells
and use as fertilizer. For each 100ml (2 eggs contents), add 10 litres
of water and mix well. Spray over crops, trees etc. using a hand or
mechanical sprayer, similar to one used for spraying pesticides.
Since eggs are safe, the dose can be doubled to 200ml/10litre of
water, if animals get accustomed to the smell.

Intense spray
Similarly, use double strength solution or more intense spraying on
the edges of the crops for about 10 feet on all the four sides of the
field or on the side (forest side) from which animals enter the field,
to repel them from a distance.
The pungent odour generated by the eggs, will repel the herbivorous
animals from entering into the field.
How long will the smell remain?
“The pungent smell remains for about a month; but during rains, the
water will wash away the egg contents over the crop. Even snow will
remove the smell quickly in about two weeks.”

Eco-friendly
Hence egg spraying has to be repeated after a rain or when the pungent
smell is lost. This egg spray protects the crops from animals; without
having any harmful side effects and is eco-friendly.
Moreover, the spill-over of highly nutritious egg liquid on the soil,
makes it more fertile.
