After four years of drought, turfgrass has taken a beating. Some people have turned off the water—the turf has turned into a few patches of grass, but mostly weeds, if anything is growing at all (Figure 1.) Others have reduced irrigation amount or frequency resulting in sparse grass and more weeds (often perennial weeds and/or drought tolerant weeds such as bermudagrass, dallisgrass, field bindweed, dandelion, narrow or broadleaf plantain, knotweed, hairy fleabane, star thistle and others.) Other people of course have removed the grass and replaced the landscape without turfgrass. There also has been a concerted effort to get people to reduce the grass in the landscape by painting with a broad brush that grass is a heavy water...

When Richard Smith tells you that he is impressed with efficacy of an organic herbicide you better take notice. Richard shared his results on this blog site last year and showed good weed control with 'Suppress' from Westbridge. This OMRI approved herbicide is a mix of caprylic and capric acids and is a contact material that interferes with plant cells membranes causing leakage and desiccation.
It looked like a good fit for organic plasticulture systems such as strawberry that have wet weedy furrows which are difficult to access with mechanical tools because of proximity to plastic. We placed a trial in a very weedy field that also had one of the SoCal...

Plasticulture tunnels are the norm for several multimillion dollar crops such as raspberries and flowers. They are not permanent structures and are don't have to comply with the standard runoff regulations for impervious surfaces, but water running off the plastic surely ends up in post rows that become water channels. These post rows are constantly wet and are great for growing weeds.
Growers with tunnels still need to comply with agricultural runoff regulations and try to manage the weeds, which can be challenging due to limited availability of effective herbicides and significant ‘organic' production (that translates to hand-weeding).
In a pilot study we looked at what would $10-15/acre worth of barley or...
