Ames, Iowa – Iowa farmers who face tight profit margins may consider cutting back on weed control efforts during the growing season but one expert says that will cost money in the long run. Iowa State University Extension agronomist Robert Hartzler, who’s also a professor of agronomy at I-S-U, says he’s concerned some farmers will ignore small populations of weeds in their fields.
He says farmers need to diversify their herbicide management programs.
Farmers should consider new tactics in fighting invasive weeds.
He says the 30-inch row spacing was introduced to allow for cultivators to pass and since few farmers are using cultivators, the narrower rows may be the best option.
