Importance of Understanding Mode of Action Groups
I wanted to talk a little about the importance of knowing your chemicals. For years, glyphosate was the answer. While still a valuable tool, we as an industry must understand chemistry’s role in growing crops. Recently the chemical industry has changed for the better, labeling packaging with Modes of Action (MOA) groups. MOA’s are simply the way each chemical disrupts the growth ability of the targeted weed species. To maximize weed control and prevent early resistance to MOA groups, it’s important to layer multiple groups per year. This applies to both pre-emergence and post emergence programs.
Pre-plant herbicides are a very effective method of preventing the germination and development of small seeded broadleafs and grasses. Taking a closer look, several post chemical options can be used for pre-plant as well. With that in mind, utilizing the same chemical group pre-plant and post emergence is quite easily done. Understanding the MOA groups and making sure we don’t double up each growing season is an important stewardship practice we all need to follow.
Our Farm Nutrients staff is equipped with the knowledge and understanding of these practices to get you the best weed control possible, all while preserving the MOA’s currently used. Unfortunately, there are no silver bullets to combat the wide array of pests we deal with in agriculture. Even more unfortunate is the fact there are no new MOA’s currently being researched, so preserving what tools we have now is paramount. Utilizing the best strategies and chemical options available, weed control can be achieved when the proper program is prescribed and followed. Look for these MOA’s as you plan for the upcoming growing season and ask you local Farm Nutrients representative any questions that may arise.
The 2020 growing season has been faced with many challenges. Several areas have been affected by minimal rainfall and devastating winds. With all the obstacles we’ve faced, I know it can be hard to start thinking about 2021 but it’s very important to begin putting a crop plan together for the upcoming growing season. We … Continue reading Crop Planning for 2021Read More >
