Pests in the Urban Landscape

As part of our coverage of California Invasive Species Action Week, today we focus on a pair of invasive species that work together: an insect called the Asian citrus psyllid and the plant disease it can spread, huanglongbing.

Did you know that every 60 days, a new and potentially damaging invasive species enters California? California residents can help in the fight against invasive species by learning and participating next week (June 2-10) in the California Invasive Species Action Week.

Nutgrass, also called nutsedge, could easily be one of the top 5 nuisance weeds gardeners deal with in the garden and landscape. While we don't know that for sure, we do know that nutsedge is a very challenging weed to control.

If you are puzzled by curling leaves on plants in your garden or landscape, you may need to do some detective work to figure out the cause. Curling leaves can be caused by many problems, including insect damage, disease, abiotic disorders, or even herbicides.

San Luis Obispo County has seen more than 20 detections of Asian citrus psyllid (ACP) since January 2018, according to Citrus Insider. The majority of these invasive insects have been found in the backyards of residential properties in the city of Nipomo.
