Which chemical can be applied to lawns to make the grass distasteful to geese?

• A. Methyl anthranilate.
• B. Glyphosate.
• C. Diuron.
• D. Imidacloprid.

Answer: (A)

Deterrents that rely on changing the taste or scent of the turf to discourage geese from feeding are a common approach to protect lawns. Methyl anthranilate works as an avian repellent by giving the grass a taste that geese find unpleasant, so repeated grazing becomes less appealing and geese are more likely to move on. This makes it the best choice for making the grass distasteful to geese.

The other substances listed are not meant as bird deterrents. Glyphosate is a non-selective herbicide that would damage or kill the grass if applied, not deter birds. Diuron is a herbicide used to control weeds, not to repel birds. Imidacloprid is an insecticide aimed at turf pests rather than influencing geese feeding behavior, and it won’t make the grass distasteful to geese.
