It is hard, if not impossible, to definitely differentiate between injury caused by these two similar herbicides. There are several keys that often can be helpful though.
1. Dicamba translocates more completely throughout a plant and better control of woody and brushy species can help: these species will be injured more by dicamba than 2,4-D.
2. Another difference is the tendency of dicamba to flatten and twist monocot leaves just after treatment, a symptom not encountered as much with 2,4-D.
3. Dicamba can drift in the air to greater distances than does 2,4-D.
4. Dicamba injury often will develop over a longer period than 2,4-D: dicamba is slower acting.
5. 2,4-D often will cause slightly more corn stalk injury under the same conditions than that caused by dicamba.
6. Dicamba has a longer residual effect in the soil than that from 2,4-D.
7. Dicamba costs more than 2,4-D, look for thrifty farmers using 2,4-D.
8. Dicamba may also act so quickly that it doesn"t form the "strap-shaped" leaves, narrow and puckered, that 2,4-D does. Dicamba injured leaves instead are shorter than those with 2,4-D.
