What chemical repellent is permitted for use on fruit crops in Pennsylvania?

Methyl anthranilate is a chemical repellent that is specifically permitted for use on fruit crops in Pennsylvania. This compound is a grape-derived compound that is effective at deterring certain wildlife, particularly birds, from feeding on crops. It works by emitting a scent that is unpleasant to many birds and other animals, thereby protecting the fruit from being consumed and ensuring a better yield for farmers.

In contrast, the other options listed are not designated for use on fruit crops in Pennsylvania. Octenol is often associated with attracting certain insect species and is not used as a repellent for wildlife; rather, it can be counterproductive in agricultural settings. Pyrethrin is a natural insecticide used to control a variety of pests but does not serve the specific function of repelling wildlife from fruit crops. DEET, well-known as an insect repellent for personal use, is not suitable for application on edible crops and is focused on repelling insects rather than preventing wildlife from damaging fruit. Therefore, the use of methyl anthranilate is tailored and approved for the unique needs of fruit crop protection.
