Fusarium Head Blight Predicted Risk for Spring Wheat
Most of the spring wheat is at or will soon be at flowering. One disease that can develop in wheat at this growth stage is fusarium head blight (FHB or scab).
Winter Wheat Diseases Update
Powdery mildew, fusarium head blight and leaf rust were observed in a few winter wheat fields recently scouted. The recent rainfall showers and warm temperatures have favored these diseases to develop in winter wheat.
Grasshoppers Are Causing Concerns in Close-to-Harvest Winter Wheat
During the end of last week, we received reports of grasshoppers feeding on winter wheat that was close to being ready to harvest. One of the questions with the report was, “What insecticide can be sprayed that won’t delay harvest?”
Late Summer 2020 Climate Outlook
Drought concerns in South Dakota may be relieved later this summer, according to the NOAA Climate Prediction Center’s seasonal outlook released this week.
Planting Spring Wheat Into Corn or Milo Residue: Considerations for Scab
Due to current grain prices and other reasons, growers may be considering planting spring wheat into fields that were planted to corn or milo last season. While this type of crop rotation is not generally recommended, economic and logistical challenges sometimes may dictate otherwise.
Fertilizing Forages in South Dakota
Spring is a busy time for South Dakota farmers and ranchers with planting, calving, and other field preparations. Soil sampling and fertilizing pastures, alfalfa, or other forages might be overlooked.
Black Grass Bug Activity Expected in Coming Weeks
Spring green-up is the time to be watching for black grass bug activity. Large populations of this early-season pest can cause severe damage to pasture (up to 90% forage reduction) and infest the edges of wheat fields.
Chloride Fertilizers May Be Beneficial in Spring Wheat Production
Chloride, the ionic form of chlorine, although not considered an essential nutrient, has long been observed to be highly beneficial to field crops. Chloride is known to play an essential role in plant development and osmoregulation.
Does Early Fungicide at Tillering Result in a Profitable Yield?
Tan spot and powdery mildew pathogens are two residue-borne pathogens that can infect wheat early in the season. These diseases can lead to poor tillering, and their continued development can lead to yield loss.
Wheat Streak Mosaic Disease Developing in Winter Wheat
Although the majority of winter wheat in the state is rated good to excellent in the recent USDA-NASS report, a few winter wheat fields in Central South Dakota have been diagnosed with wheat streak mosaic disease (WSMD) caused by wheat streak mosaic virus (WSMV).
