Figure 1. Southern rust has been confirmed in corn in eight eastern Nebraska counties and growers are urged to scout from now through August, as weather conditions are quite favorable for its development.
Southern rust has been confirmed in corn in 8 eastern Nebraska counties and growers are urged to scout vigilantly to schedule optimal timing of treatment, if needed. Most systemic fungicides can provide protection of leaves from future infections for 21-28 days.
Corn growth stages are estimated for 41 sites in 10 states and yields are estimated for select irrigated and rainfed sites, based on the Hybrid-Maize model and input from specialists and educators across a 10-state area as of July 18, 2017. The authors note that these early season yield forecasts vary widely, particularly for rainfed fields, and may change considerably by end of season.
This week recently retired Nebraska Extension Educator Gary Zoubek was awarded the Hall of Fame Award for the North Central Region at the National Association of County Agricultural Agents (NACAA) national meeting in Salt Lake City, Utah. his is the highest honor an Extension agricultural professional can receive from NACAA.
This article discusses data and data collection for the Yield Forecasting Center forecasts of crop phenology and yield for 2017, including a map of the site locations and specific data on crop management and soil types for each site.
Agronomists consider several options for those pushed into late planting due to heavy rains. Changing corn hybrids or soybean varieties is not recommended, nor is shifting to alternate crops.
Nebraska soybean and corn yields steadily increased from 1971 to 2016, in both irrigated and rainfed production fields. Charts based on USDA National Agricultural Statistics Service numbers track these changes.
Palmer amaranth has not been confirmed in conservation plantings in Nebraska; however, the identification and occurrence of Palmer amaranth in CRP fields in Iowa has raised concerns among weed scientists and growers about its spread into conservation plantings in Nebraska and offer some suggestions for growers.
Wheat fields are still looking green (Figure 1). However, development of several diseases is increasing. On April 26, stripe rust was confirmed in Nuckolls County in south central Nebraska and on April 27, it was found at low to moderate levels in research plots at the University of Nebraska-Lincoln’s Havelock Research Farm near Lincoln in Lancaster County (Figure 2).
