Maintaining a lush, green lawn involves more than just regular mowing and watering. To combat common lawn diseases and pests effectively, it’s crucial to understand the different modes of action of lawn care chemicals. Let’s delve into three main categories: contact, systemic, and translaminar, shedding light on their functions and recommended applications.
Contact fungicides, such as the popular brand RoundUp, target diseases like brown patch by treating the surface of the leaf blade. These chemicals act swiftly upon application, directly combating the pathogens on the leaf’s exterior hence the name Contact. However, it’s important to note that their effectiveness is limited to the treated area and won’t penetrate deeper into the plant.
Systemic herbicides and insecticides work by being absorbed and transported ONLY upwards through the plant, offering comprehensive protection. By watering them into the soil at the root level, systemics like those used for grub control can treat the entire leaf blade, effectively managing issues like dollar spot. This approach ensures long-lasting defense against pests and diseases.
Translaminar or Stroben fungicides, exemplified by brands like Heritage by Syngenta, offer a unique mode of action. These chemicals are absorbed by the leaf and can move both upwards and downwards along the blade, providing extensive coverage. They are particularly effective against diseases like Pythium Root Rot, penetrating the plant’s tissues to combat pathogens from within.
For homeowners who may be unfamiliar with these diseases and their symptoms, we highly recommend referring to one of our previous blog post, where we discuss common lawn ailments in detail. Understanding the signs of distress in your lawn is the first step towards effective treatment and prevention.
Choosing the right lawn care chemicals depends on understanding their modes of action and the specific issues they address. Whether opting for contact fungicides for surface-level diseases, systemic solutions for comprehensive protection, or translaminar treatments for deep-rooted pathogens, informed decision-making is key to achieving a healthy, vibrant lawn. By incorporating these insights into your lawn care routine, you’ll be better equipped to combat challenges and nurture your outdoor oasis for years to come.
