You will be prompted to select when exposure to dicamba occurred (V3/V4 or R1/R2) by clicking on the Growth Stage at Exposure link below. For all variables except plant height reduction, enter injury level based on 0 to 5 where:
Clicking on the icon next to each variable will provide photos showing representative ratings for 1, 3, and 5.
For plant height reduction, injury level is based on 0 to 100%. As an example, if plant height of affected soybean plants is 10 inches and non-affected plants are 20 inches, height reduction is 50%.
It is important that if injury or height reduction is not observed that “0” be entered. If injury level or plant height reduction varies across the field, an average value representative of the entire field can be entered or the field can be sub-divided with values entered for each area of the field to obtain an average yield loss for the entire field.
After data is entered, click on the Yield Loss Calculation link.
