North central entomologists, led by Dr. Anthony Hanson at UMN, have developed a survey to assess the needs for future alfalfa weevil applied research and extension topics. Pyrethroid resistance is a concern and one of the topics we are trying to assess with this survey. If you haven’t already, please click the link or scan the QR code below and add your input. It takes only a couple of minutes and will be used to guide our efforts on applied research! Take the survey
Sulfur Deficiency
Sulfur (S) deficiency has become more common in
Indiana crops because S emissions from coal-fired power
plants have decreased over the past few decades
(Camberato et al., 2022). Consequently, atmospheric S
deposition to soils has also decreased.
Sulfur deficient corn plants exhibit a general yellow-
green color from top to bottom of the plant, often also
with visible leaf striping (Fig. 1). Other nutrient deficiencies
can cause striping and can sometimes be confused with S
