Strawberries are traditionally grown with a matted-row system in Indiana. Plasticulture is relatively new. It brings market opportunities and potentially high income. However, growing strawberries in plasticulture is much more expensive than the matted-row system. Farmers need a good understanding of the system to avoid significant economic loss. In the Strawberry Chat Podcast episodes, you[Read More…]
Crop Management
Shoot Thinning The optimum shoot density is 5-6 shoots per foot of row. Thinning to this density can help reduce shading, adjust the crop, lower the risk of disease and improve spray penetration. The optimal time for shoot thinning is before the shoots reach 12 inches. Much of the state is past this point, so[Read More…]
As strawberry harvest winds down, attention turns to strawberry renovation. Renovation consists of mowing existing strawberry foliage (Figure 1) and, in matted row systems, cultivating to reduce row width. When combined with strategic herbicide applications, this can be a great time in the production cycle to catch up on weed management or maintain your level[Read More…]
When Neil Young was singing about “Rust Never Sleeps,” I doubt he meant orange rust, caused by the fungus Gymnoconia nitens (formerly Arthuriomyces peckianus). But who knows? Maybe he did? And he’d be right: This rust is definitely not sleeping! Despite unusually dry conditions throughout much of the state, orange rust is still making its presence known[Read More…]
The harvest season may not have ended yet; it is time to plan for the new planting. This article summarizes options for planting materials and considerations for plasticulture-grown strawberries in the region. Purchasing plug plants Plug plants are like vegetable transplants with actively growing root systems. Plug plants are much easier to establish than bare-root[Read More…]
Currently, the US Drought Monitor (https://droughtmonitor.unl.edu/CurrentMap/StateDroughtMonitor.aspx?IN) places Indiana in the ‘abnormally dry’ category. With no rain in our 10 day forecast, I expect that to only get worse, and with it, powdery mildew on all fruit crops. Powdery mildew is identified by the white, powdery growth on leaves and shoots that consist of the fungal[Read More…]
Shoots are at various stages of development across the state with some shoots at or near bloom. The most important time of the year for fruit disease control is from pre-bloom to 4-5 weeks past fruit set. The potential for fruit infection drops significantly 4-5 weeks post-bloom. Important diseases to control during this time include[Read More…]
This time of year, my email inbox and phone text messages are filled with ugly photos of fruit and vegetable crops affected by suspected herbicide exposure. Sometimes the symptomology points toward a clear cause and effect, but most of the time the answer is not so clear-cut. Here are a couple recent examples: Cupping and[Read More…]
Growing strawberries under high tunnels can extend the harvest season, provide protection against rain, frost, and disease, and improve overall yield and fruit marketability. Pest pressure, however, can be higher on protected culture strawberry compared to the open field. This is especially true for small, soft-bodied pests such as spider mites, aphids, and thrips. Even[Read More…]
