Citrus integrated pest management (IPM) programs typically utilize a combination of control practices, like cultural, mechanical, and chemical, to minimize competitive effects of weeds on crop productivity. Weed management can be an expensive part of the total citrus production program, but resources invested here can provide significant economic returns.
Tree age and variety considerations
The smaller canopies of younger trees allow more light to reach orchard floor, promoting greater weed growth, which can lower yield by 23-33% compared to mature groves (Singh and Sharma 2008). Sensitivity of citrus trees to the various registered herbicides varies, depending partly on tree age. While mature trees...

Developing, managing, maintaining and testing an early detection and rapid response program (EDRR) will enable property owners to combat new weeds before they become a problem. EDRR is a system used to find new weeds and then treat those weeds before they spread and become an even greater problem. An early detection and rapid response program has four main components: education, monitoring, assessment, and management.
Education: Education includes teaching people to look for weeds and providing information on some of the most likely weeds to invade your area and identifying unknown specimens. In California, a variety of agencies and programs can be used to learn about weeds in your area from UC Cooperative...

A recent find in El Dorado County has weed scientists, land managers, foresters, botanists, and plant conservationists throughout Northern California really excited over a tiny insect-like animal. The broom gall mite (Aceria genistae) which is actually not an insect but more closely related to spiders and ticks has recently taken residence on the invasive plant Scotch broom (Cytisus scoparius). Scotch broom was introduced into North America in the mid-1800s from Europe as an ornamental and for erosion control. The bright yellow flowers and rapid growth has made it a prized ornamental however its ability to out-compete native plants and form dense stands has also made it one of California's worst wildland weeds....
