To develop a new foliar spray treatment for iron chlorosis, a yellowing of plant leaves caused by iron deficiency.
Current treatments for iron chlorosis are ineffective and there is clear need for better approaches for treating pulse crops. Our new treatment is an iron-enriched foliar spray that adheres to crop leaves and allows efficient iron uptake into the plant. The key component of the foliar spray was a newly-synthesized chemical reagent called an anionic gemini surfactant. Under all conditions explored, our new foliar spray significantly increased iron levels in plant leaves and stems above that found in untreated control samples as well as samples treated with a commercial comparison spray. The treatment was successful and appears to hold excellent potential for treating iron chlorosis.
