Tank Mixing Iron with Herbicides May Reduce Crabgrass Control

摘要

Smooth crabgrass (Digitaria ischaemum [Schreber], SchreberJ is a common invasive weed throughout the United States. It is a summer annual capable of prostrate growth and reproduces primarily by seed. Crabgrass occurs in most crops, turfgrasses and landscapes. It can grow in most soil types while also tolerating low fertility and dry conditions [Uvaet.al., 1997). A variety of chemical agents target poste-mergent control of crabgrass. Traditionally, organic arsenicals such as MSMA and DSMA, have been used for postemergent crabgrass control.
