You might have heard about the 4Rs of nutrient management: applying the right product at the right rate at the right time and in the right place.
Now, we can take those same concepts and apply them to a wild oat program.
First — the right product. Look at whether you’re dealing with a light or heavy wild oat infestation and then pick a product that’s suited to the task. Consider using a fully serviced product, which gives you technical support and backing for added insurance.
Second — the right rate. Always use the rate that’s listed on the label, even if it means spending a few extra dollars. Stretching or skimping on rates may appear to work at first, but in the background, those wild oats could be developing resistance and multiplying.
Third — the right time. Wild oats can quickly reduce the amount of nitrogen available to your crop. Getting rid of them early reduces inter-crop competition, allowing your crop to intercept sunlight and use more nutrients.
Fourth — the right place. Wild oats’ vertical leaves can make them a really difficult target for herbicide applications. Make sure you’re getting even coverage by using proper water volumes and slowing down your sprayer travel speeds.
