Cercospora is generally more severe than it has been over the past 10 years

Daily infection values (DIV's) levels have been high

Infection occurred earlier this year

Disease levels are higher in the south and lessen as you go north

Most fields have some disease and some fields are "pretty hot"

Here are some tips for the rest of the year:

Apply Headline 30 to 45 days before harvest for plant health and to reduce frost susceptibility

Closely monitor your fields

Don't stretch intervals between fungicide applications

Watch the infection values

Don't let the disease build up in September

Use as many sprays as necessary to protect the crop

Watch the pre-harvest intervals (PHI's)
