Enhancing Plant Physiology
The process of photosynthesis relies on a number of conditions to produce energy for plant growth. As discussed in previous posts, light, water and carbon dioxide are the main components for photosynthesis. When there is a greater amount of green leaf area exposed on a plant, the plant is able to take in a greater amount of sunlight for photosynthesis. Similarly, there is increased area for the reactions of photosynthesis to occur.
The longer plants maintain their green leaf area, the more time there is for photosynthesis to take place, the healthier the plants are and the greater chance for plants to achieve their maximum yield potential. By allowing a plant to live its full lifecycle without early senescence – the aging and drying of leaves – azoxystrobin enables leaves to use the sun’s energy longer through photosynthesis. The plant is able to maintain healthy, green leaves longer, improving plant quality and maximizing yield at harvest.  Maintaining green leaf area to maximize the full lifecycle of a plant should not be confused with green stem disorder of soybeans.
