Tracking the western bean cutworm moth flight wouldn’t be possible without the many pheromone trap cooperators in our network, see following “Western Bean Cutworm Pheromone Trap Report.”
Tar Spot – We continue to confirm counties with active tar spot.
It is important to continue to scout for diseases in both corn and soybeans. Recent rains have created favorable environmental conditions for the development of foliar diseases in both crops.
The biggest challenge so far this year for Indiana corn production has been the dry conditions experienced throughout the state (Figure 1).

This summary is based on 55 field scale research trials conducted at Purdue Ag. Centers and with on-farm collaborators around the state of Indiana from 2014 – 2022.
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
Although yield is always at the forefront of many corn farmers and agronomists’ minds during harvest, another important discussion topic each fall is that of grain test weight.
