Fairy Rings in Lawns
Seeing greener grass in circular pattern in your lawn? This is not due to uneven fertilizer application, but rather due to a fungi feeding on decomposing matter and releasing nitrogen in the affected areas.
Scout for Tan Spot in Winter Wheat
Tan spot was observed in a few winter wheat fields scouted recently. It is important to scout winter wheat for tan spot and other early diseases developing before deciding to apply an early-season fungicide tank mixed with herbicide.
Watch Closely for Weed Emergence
Cool, dry conditions have slowed weed emergence and growth, but dry conditions also have limited the activation of preemergent chemicals. Given this scenario, fields need to be scouted closely to ensure that weeds do not get away.
2020 Plant Disease Summaries for Small Grains
A number of field trials were implemented in the 2020 growing season with the general objective of assessing various disease management practices suitable for South Dakota growers and the Great Plains.
Organic Herbicides: Garden and Flower Bed Weed Control
Many South Dakota homeowners do not want to use inorganic or synthetic herbicides due to potential health impacts. Organic herbicides can be a useful tool for weed control when combined with other management practices.
Crop Tolerance to Soil Herbicide Residual
Some herbicides can persist in soil, especially dry soil. Herbicide carryover could be an issue in 2021 across the state depending upon last year’s moisture levels and field conditions.
Wheat Streak Mosaic Developing in Winter Wheat Fields
A few winter wheat fields in central South Dakota have been found with wheat streak mosaic disease. Incidence of this disease varied from a few plants to large portions of the field with yellowing leaves.
