Don't treat them as pests...its just repayment of loan to
nature for using their land. Dr. V.S.Sheshadri
We have found
"Marigold" as an excellent way to control insects that gorge on
Tur, Cowpea, Alasandhe and other crops. Marigold flowers act as
preferred hosts and attract most of the insects. We have
observed minimal crop loss with this technique. Marigold also
has a good commercial value fetching sometimes upto Rs10/kg in
the wholesale market. So we have saved on pesticides and have
also got some additional income out of the same.

For "Tur" another
method that we found effective, was to have long sticks with
branches planted at regular intervals (appx. 10x10 ft) in the
midst of crop. The length of the sticks have to at-least couple
of feet longer than Tur plant. Birds which perch on these
branches have a vantage point over the crop and act as natural
biological control. With this method we observed that there was
no crop loss. This almost a zero investment crop protection
method.
One of the
natural occurring predators that we have found controlling the
pests has been spiders. We have been witness to many insects
having fallen to the trap meticulously laid by these master
weavers.
We are having a
big issue with wild pigs, which seems to destroy our Ragi,
Maize, Tur, Ground nut crops a number of times. But interesting
point is that these invasions seem to be only on occasions where
ours is the only crop in the vicinity. When Ragi was grown along
with other farmers at the same time as others we have seen
minimal losses....probably the pigs went on sampling all over
and impact was evenly spread. Though we are fenced for solar
energizer, somehow never felt comfortable to use electric shock
as the deterrent. we still don't have a effective solution to
prevent these incursions. Will really appreciate if someone can
suggest a viable option to contain wild pigs.
