Southern Rust
Southern rust has now been confirmed in at least 15 states, and with high heat and humidity this week, along with strong winds, agronomists are encouraging farmers to scout their corn fields, as conditions are ripe for the disease to spread.
Both diseases are showing up earlier this summer than last year, according to Daren Mueller, Iowa State University plant pathologist. He says a new interactive tool from the Crop Protection Network can help farmers locate these diseases, and others, faster.
Corteva Forcivo will feature three modes of action to address foliar diseases in corn, soybeans, wheat and other crops via overlapping preventive and curative activity.
Iowa farmers say a foliar fungicide application can add more bushels per acre by preventing losses to disease pressure and minimizing the impact of environmental factors, such as heat stress and drought.
There’s a big crop in the field for many Midwest growers, and it requires fuel. N supplies ears with the energy they need to add kernels all the way to their tips and to pack on weight.
If you have tar spot, Southern rust or other disease pressure and plan to dry the crop in the field, you might want to spray again.
