Leaf Rust Impact on Wheat
When affected by leaf rust, the energy that the plant would typically allocate for growth and grain production is instead redirected to combat the disease. This energy diversion can result in smaller, less productive plants and a significant reduction in grain yield.
Leaf rust primarily targets the leaves of the wheat plant. The pustules disrupt the photosynthetic tissue, undermining the plant's ability to produce food. This disruption can lead to stunted growth and reduced grain size. In severe cases, the disease can also impact the stems and heads, leading to further yield reduction.
