It’s a challenging time for crop producers to manage input price risk. Input prices for fertilizer, crop protection (chemicals), machinery, fuel, labor, rent, and insurance are up substantially compared to last year at this time. Additionally, availability and timeliness of delivery are a major concern. Fertilizer prices highlight this dramatic increase in the cost of production (graphs above). Most common fertilizers have more than doubled compared to last year. As such, producers are seeking strategies to reduce input costs. Two recommendations, as a starting point, are soil sampling (know what you’ve got) and crop selection (know current relative cost and revenue relationships for commodities produced on your farm). Unfortunately, there is no “silver bullet” to mitigate rising input costs and availability concerns. So, producers will need to be creative in their approach and consider numerous strategies.

We can learn a great deal by comparing notes. Slicing bolls is one of the best ways to time defoliation- and most agree on what represents a ‘mature’ boll (dark seed coat color, no jelly in seed, hard to slice with a sharp knife). But when it comes down to it, there is a large amount of variation in what each of us, as agronomists, consider to be a boll that could potentially be opened by ethephon. With cool temperatures in the forecast on what remains a late crop, many are trying to figure out which bolls might be opened with an application and when to start. To get the conversation started, I texted the above picture to a few dozen individuals within the industry to get their thoughts on this question- what is the lowest number boll you believe you can open with ethephon?
