Spring season was as fast as it ever has been for us all this year. With little rain and good ground conditions most of the crop went in without much for issues at all! We have seen some replant around the area and a fair amount of crusting issues caused by some driving rain and hail in some places.
As we turn the page to post spraying it is going to be more important than ever to make sure you have a robust herbicide program in place. While there are many perks to an early planting including better yields typically; the down side is a longer window that we need to control weeds. We also need to be aware that in many cases our pre herbicides have already been out for 4+ weeks with little moisture to properly activate them. This means we will likely see ragweed and waterhemp start rearing their ugly heads soon if they haven’t already. This rain we are getting will likely give us a bit of “reachback” activity on small weeds but it will not be 100% at all.
As you are finalizing post emerge herbicide programs consider thinking about a layered residual or a sequential pass plan if you have not already. Another thing to think about is checking your adjuvant program. The efficacy of herbicides is heavily dependent on the adjuvant package in the sprayer tank. Consider adding in a product such as Level Best to assist in water conditioning and to speed up the kill on tough weeds and grasses. We have seen significant benefits from the addition of this product in the tank. Read this article on adjuvants from our LIFT academy. Be sure to consult your agronomist about your herbicide plan to make sure it is still the right plan for the weeds in your fields.
Thank you for your continued support and business!
