UC introduces a new way to manage weeds in caneberry growing tunnels

Planting cover crops in tunnel anchor rows reduces the use of herbicides.
Growing caneberries under tunnels keep the berries dry even when it rains, preventing disease and assuring fruit quality. However, during rains, water drains from the plastic down into rows that contain the anchoring posts of the tunnel structure. The accelerated runoff in these post rows causes soil erosion and sediment and nutrient loss. Persistent soil moisture in post rows also promotes weed growth. While weeds growing in the anchoring rows do not directly compete with canes, they can reproduce and quickly spread into neighboring cane rows.

Rather than using herbicides in caneberry growing tunnels, the UC Integrated Pest Management program suggests planting a cover crop to prevent weeds in anchor rows.

Cover crops in anchor rows can suppress weed growth and help to minimize soil erosion and nutrient and sediment loss when it rains. Densely planted cover crops can out compete weed seedlings germinating from the soil and prevent wind-dispersed seeds from reaching the wet soil surface.

Cover crops are especially helpful when managing weeds that are difficult to control with fumigation because of their hard impermeable seed coats (mallows and filaree), or  resistance to herbicides such as glyphosate and paraquat (hairy fleabane and horseweed).

Cover crops can be managed with mowing or herbicides to avoid seed production.

For all the details, see the newly revised weed section in the Caneberries Pest Management Guidelines on the UC IPM web site.
