Pre-harvest burndown herbicide applications can lower seed losses, reduce staining and make combining a smoother process, according to a September 2020 article posted to Field Crop News.
The article said crop quality often increases because harvest timing after the field has been sprayed is more predictable, so harvest schedules can be better managed.
A pre-harvest burndown will dry down weeds so combining is easier and will help clean fields for winter wheat planting.
Growers should contact their buyer to verify acceptable pre-harvest products. Use of glyphosate is not allowed according to some food-grade soybean contracts.
