Cheverus High School seeks pesticide amendment to combat turf grub infestation

The City Council of Portland, Maine, convened on March 3, 2025, to address a pressing issue regarding turf management at Cheverus High School, which has been grappling with a significant grub infestation affecting its athletic fields. The meeting began with a detailed report on the challenges faced by the school in managing the grubs, which have caused extensive damage, including large bare spots and uneven surfaces that pose safety risks to athletes and officials.

The school has attempted various organic treatments in compliance with the City’s Landcare ordinance, including applications of Bacillus thuringiensis (BT) and the use of decoy wildlife to deter animals from digging. However, these efforts have not yielded the desired results, prompting the school to propose the use of Acelepryn, a synthetic pesticide deemed the least risky option available for grub control.

City officials reviewed the waiver application for Acelepryn but determined it was ineligible due to the application method, which involves a broadcast spreader not permitted under current regulations. Legal counsel indicated that an amendment to the ordinance would be necessary to allow this treatment. The Landcare Management Advisory Committee (ELMAC) was consulted and subsequently voted to recommend amendments to permit Acelepryn under specific circumstances.

During the public comment period, representatives from Cheverus High School emphasized the urgency of their request, citing the potential for injury to student athletes and the need for equitable treatment compared to other city-owned venues that are exempt from the ordinance. They argued that the current restrictions hinder their ability to maintain safe playing conditions.

Opposition to the amendment was voiced by several community members, including environmental advocates and concerned citizens, who argued that weakening the pesticide ordinance could have detrimental effects on public health and the environment. They highlighted the potential risks of synthetic pesticides to pollinators, aquatic life, and overall ecosystem health.

The council's discussions underscored the tension between maintaining safety for athletes and preserving environmental protections. As the meeting concluded, the council was urged to consider the broader implications of any amendments to the pesticide ordinance, with many speakers advocating for a continued commitment to organic land management practices.

The council will deliberate further on the proposed amendments, weighing the need for effective turf management against the city's environmental goals. The outcome of this discussion will be crucial for the future of turf management practices in Portland and the health of its athletic fields.
