Spraying pesticide or fertilizer soon could become more efficient — and high-tech — for Iowa farmers.

Representatives from Rantizo, an Iowa City-based drone company, touted its enhancements to existing aircraft to a small group of farmers, including some with a future interest in growing hemp, Friday afternoon at Fireside Winery in Marengo.

Vineyard grapes are just one example of the high-value, low-acre crops the drone technology can benefit, with other possibilities including cannabis, berries and fruits, said Rantizo CEO Michael Ott, who founded the company in early 2018.
