Abstract

Stress can result in up to 70% losses during crop production. Plants are exposed to abiotic stresses, such as drought or salt, or biotic stresses, such as fungal pathogens like powdery mildew or septoria. Reactive oxygen species (ROS) signalling is a part of a common response to plant stresses, but excessive ROS can be damaging. Plants produce antioxidants to reduce ROS. Wheat plants were exposed to drought stress, salt stress, and biotic stress from powdery mildew and septoria. In a glasshouse, wheat plants were treated with a functional fertiliser (Indra containing Oxygon chemistry, Levity Crop Science, UK) that could reduce the impact of stress via potential antioxidant production. For the drought, salt, and powdery mildew stresses, the functional fertiliser reduced the impact of the stresses so that the plant growth was significantly better than the plants exposed to the stresses. Under field conditions, the functional fertiliser gave control of septoria when using four fungicide applications that was comparable to seven applications without the functional fertiliser. In this work, the application of a functional fertiliser reduces the damage caused by four stresses. This gives farmers a tool to help prevent yield losses associated with plant stress.
