Iron sulfate for the control of dollar spot disease
Rudland Matthew,Sang-Kook Lee,Hsiang Tom 한국잔디학회 2023 Weed & Turfgrass Science Vol.12 No.4
Iron is an essential nutrient for living organisms and has critical functions in many cellular processes. However, excess soluble iron in plant cells leads to the formation of harmful hydroxyl radicals that can negatively affect the plant. Ferrous sulfate has been used to green up turfgrass for decades, but more recently, the use of ferrous sulfate has been reported to reduce turfgrass diseases such as Microdochium patch and dollar spot. This review describes some of this research emphasizing efficacy against dollar spot, as well as the mechanisms by which iron enters the plant and exerts its effects, and provides recommendations for the use of ferrous sulfate in managing dollar spot disease.
