Why scout for weeds?
While weeds are present in every orchard, there is variation in the weed species composition and density from orchard to orchard. Scouting for weeds is the basis for a good Integrated Weed Management (IWM) plan. Information gathered from weed scouting allows growers to:
- Evaluate the current year's weed control program
- Adjust control practices for the following year
- Discover weed stands and possible resistance before they spread throughout the orchard
- Select the best control option for species of concern, such as:
- Choosing appropriate management...

Have you listened to a Growing the Valley podcast? Here are a couple you might want to check out.
In this short episode, Phoebe Gordon chats with Dr. Brad Hanson, Weed Specialist with UC Davis. They talk about perennial weed management, as well as two species that have recently become problematic in orchard crops: alkaliweed and threespike goosegrass. We don't know a.../h4>
Summer grass weed species are becoming more troublesome in orchards in the Central Valley of California. Feather fingergrass, junglerice, sprangletop and threespike goosegrass, to name a few, are summer grass weed species that germinate (or in some cases, resume growing) when the soil temperatures start to rise in the spring, develop during the summer and complete their life cycle in the fall. With such a life cycle, summer grass weed species reach their maximum biomass accumulation late summer/early fall – coincidently when harvest operations are taking place – if previous weed management approaches were inefficient. To make matters worse, some of the mentioned weed species have some degree of glyphosate...
