Mar 31, 2024 · Wheat is a crop that depends heavily on foliar tissue to fill grain heads, so foliar diseases can greatly impact yield. According to The Ohio State University, the flag leaf makes up approximately 75% of the effective leaf area that contributes to grain fill.

Mar 16, 2007 · Fungicide applications are aimed at maximizing green leaf area of the top leaves during grain fill. In wheat, the flag leaf contributes the most to grain fill, followed by the flag-1 leaf. Therefore, to maximize yields, fungicide applications should be timed to protect the flag leaf.

Feb 2, 2016 · Wheat has great potential to benefit from foliar feeding. Studies indicate positive response to foliar feeding at various stages of wheat growth. The obvious choice for a producer to use this method of fertilization is when they are already making crop protection applications to …

The common foliar diseases of wheat include powdery mildew, rusts, and leaf blotch complex. Scout for foliar disease in wheat from jointing to flag leaf emergence (Feeke’s 4-9). Several fungicides will provide effective control of foliar disease in wheat.

Wheat—rate the flag leaf (F) and the second leaf from the top (F-1 leaf) on the same plant when the crop has reached the early dough stage. Keep separate results for the F and F-1 leaves. Since head diseases are common contributors to yield loss in wheat in Kentucky, also make disease assessments of 10 to 30 wheat heads per treatment. As with

Aug 14, 2015 · Winter wheat is usually planted right after soybean harvest here in the Upper Midwest, and is usually not fertilized at that time. Later in the growing season, foliar applications of fungicides have often shown yield increases due to suppression of fungal diseases.

Wheat rusts (yellow, leaf, and stem rust) and powdery mildew are important foliar diseases affecting wheat yield around the world. Many efforts have been done to improve wheat resistance to these diseases that lead to new phenotyping methods and …

Foliar diseases may reduce yields or grain quality if they build to significant levels; Key diseases to monitor include stripe rust, leaf blotch complex, and powdery mildew; A timely and informed fungicide application targeting the flag leaf and head can minimize yield losses in …
