This poster was presented at the Weed Science Society of America (WSSA) Annual Meeting. Deciding what tool or tool settings to use for in-row cultivation is not always obvious. If a crop is taller than a weed than tools that can precisely hill between those heights is an obvious choice for selective cultivation. Similarly, some growers will do a ‘tug’ test to see how well crops and weeds are anchored by their roots. If the crop has much greater “anchorage force” relative to nearby weeds, than tools that do some uprooting may be the best choice. The research presented in this poster explores whether such simple observations at different stages of crop-weed growth provide general insights into which type of tool and mode of action to apply. Can mathematical models based on these observations be used to identify general principles of tool selection and efficiently generate and test hypotheses to improve the chances of success?
