Learn how to keep soybeans greener longer
Colors are important in agriculture. There are red tractor people and green tractor people. There are red seeds and green seeds. But when you look at the rainbow of colors in agriculture, green is one of the most important indicators when it comes to a soybean plant
A green plant can tell your customers that their crop is growing efficiently from the time it emerges from the ground until it reaches the end of the reproductive stages. But what if there was a way for us to help soybeans stay greener longer and more productive, leading to maximized yield potential? That’s where BASF fungicides come into play.
Fungicides are applied to soybeans to help control diseases like target spot and frogeye leaf spot, but Priaxor® fungicide also provides the additional benefits of growth efficiency and stress tolerance. The combination of these three benefits is what drives BASF Plant Health. By helping plants stay greener, healthier and more productive throughout the growing season from these three benefits, your customers may see more consistent yield improvements.
When soybeans are able to stay greener longer, it means the grain bins can be fuller come harvest. In order to do that, it’s important to have a plan in place to proactively manage diseases, help reduce stress and increase photosynthesis in order to generate higher yields. In strategizing how your customers can maximize their yield potential, combat disease pressure, and enable the plant to stay greener for longer, consider the three parts of the plant: the bottom, middle and top.
Preserve bottom leaves
It’s important to preserve and retain the bottom leaves on the plant throughout the season. Often leaves are dropped when the plant is under stress from factors such as diseases or adverse weather like high heat or hail. One way Priaxor fungicide can help decrease stress on soybeans is by reducing ethylene (a plant hormone) production.
When a plant is under stress, it produces ethylene, which is the same gas that initiates fruit ripening. In soybeans, ethylene production shuts down plant growth and reduces productivity, which may lead to leaf senescence or premature pod dropping if not addressed.
A preventative application of Priaxor fungicide can help promote nitric oxide production in the plant, which inhibits ethylene, so the plant can continue to grow, be productive and recuperate more quickly once the stress is mitigated. By inhibiting ethylene production, Priaxor fungicide helps plants hold more leaves and allow the soybeans to stay green longer.
Maintain middle leaf growth
Unlike corn, yield potential in soybeans is determined by the middle third of the plant. In corn, the ear is the ultimate sink for sugar and other carbohydrates, so photosynthetic production from the entire plant helps to drive ear production. With soybeans, on the other hand, carbohydrate distribution is more localized so that pod fill is driven by the photosynthetic production from the neighboring leaves. Retaining the green leaf tissue throughout the plant helps transfer the energy to all of the developing pods, filling them and helping them grow more efficiently.
Conserve top leaves
The top leaves of the soybean plant are the leaves that most often get the greatest amount of sunlight. A proactive Priaxor fungicide application, between the R2 and R4 growth stages, can maximize the amount of photosynthetic production in your customers’ soybeans.
Photosynthesis is the engine that drives yield. So, when photosynthesis operates efficiently, and disease pressure is managed, plants grow healthier and stay greener longer.
In 2014, BASF conducted a research trial at their research facility in Seymour, Illinois, to learn more about this relationship between photosynthesis and yield when Priaxor fungicide was applied. Three days after the soybeans were treated with Priaxor fungicide at the R3 growth stage, it was found that there was an 8.7 percent increase in photosynthesis which resulted in an 8.8 percent increase in yield or 5 bu/A compared to the untreated group*.
Help your customers put their green thumb to work by educating them on the benefits of making preventative applications of Priaxor fungicide to not only have strong disease control, but also to help their soybeans can stay greener and more productive longer.
