WebSep 27, 2024 · Research has shown a negative response of corn yield to the accumulation of temperatures above 86 °F (30 °C). Heat stress during flowering can reduce yield by inhibiting successful pollination and by reducing net photosynthesis, although negative effects on pollination are relatively rare. WebJun 14, 2024 · Tar spot pressure in corn is fueled by cool (60-70 degrees F), humid conditions (>75% relative humidity) and prolonged leaf wetness (>7 hours). Therefore, tar spot pressure is typically higher in areas such as those closer in proximity to the great lakes (e.g., Northwest Indiana), river bottoms, and irrigated corn acres.
