Summer grass weed species are becoming more troublesome in orchards in the Central Valley of California.

Weeds compete with crops for light, water, and nutrients, which can result in yield reductions. Weeds can also interfere with crop production by serving as alternate hosts for pests and pathogens, providing habitat for rodents, and impeding harvest operations, among other impacts.

The Healthy Schools Act was originally developed as a notification program to let students and adults who work or visit schools to know when pesticides were going to be applied.

Postharvest management of weeds in annual systems is important to prevent larger weed problems the following year. For tomatoes, perennial weeds like field bindweed and little mallow can be especially problematic.
