Summary:

In the Philippines farmers are being asked to stop spraying their onion plants. They are asking this to stop the spray because the larvae are so deep in the soil the spray is ineffective to kill the bugs. Currently the farmers spray when they see the damage but the spray kills the natural predators of the bugs.

Response:

This is a type of an example we have seen in class. This is the classic problem concerned with spraying pesticides. The spraying seems to be in vain because the bugs are still doing damage to the plants. If they would stop the predators could manage the bugs. If not we could put more predators in the fields. This is the better more natural approach  to the problem.
