Last spring, we had a serious problem with weeds in one of the sunflower fields in central Poland. It was after heavy spring rains, which made it ideal for weeds to grow and, by the way, the farmer, using Cropler agri-camera, was able to see where crops were underperforming. A closer look with our tools revealed that the culprits were common lambsquarters (Chenopodium album) and pigweed (Amaranthus spp.), both aggressive; those can easily destroy sunflowers, especially during the early developmental stages. Most likely, the infestation was from dormant seeds in the soil seed bank that germinated with the warm and wet conditions of early April. Because of the rain that delayed the field, the pre-emergence herbicide application was late, which made the problem even worse. Using Cropler's NDVI field cameras, we identified areas of the field where crops were not doing well. With clear RGB images, we confirmed just how bad the weed problem was. Analysis showed about 15% of the field was affected with some areas worse than others. Instead of using general treatments, we went for a focused approach. We recommended special herbicides developed for sunflowers on the most affected areas, using precision sprayers to reduce chemical usage and environmental impact. In places with a moderate number of weeds, we used mechanical hoes between rows to take out weeds, along with manual weeding where machines could not go. Meanwhile, for the unaffected majority of the field, we worked on prevention, including shallow tillage to disrupt weed seed germination and planning for offseason cover crops to suppress future outbreaks. We monitored the field daily with Cropler's RGB and NDVI systems to effectively gauge how well weed control was working, and to be able to locate any new growth. Within two weeks of treatment, weed presence in the problem areas dropped by 85%, allowing sunflower growth to regain momentum toward normal. Two months later, at the time of harvest, this farmer reported that 98% of the field was clean of weeds, matching yield expectations before the weed infestation. With all the above in mind, we drew up a detailed plan with the farmer, including herbicide application at the right times, crop rotation with cereals in order to break the weeds cycle, and making buffer zones with cover crops to prevent problems from arising once again.
