Abstract

In This Issue:

  • Postemergence Shattercane Control in Corn
  • Algae and Moss Control in water and stock Tanks
  • New Registrations

Postemergence Shattercane Control in Corn

Postemergence control of shattercane in corn is limited. Bladex 80W or 90DF used with vegetable oil or a surfactant can be used before corn exceeds the 4-leaf stage. The Bladex label does not claim shattercane control. Our observations are this treatment stunts small shattercane plants but may not kill them. Similar results may be obtained with 2 qt./A atrazine used with crop oil concentrate. Tandem used with Bladex or atrazine will improve activity. Similarly, Prowl used with Bladex or atrazine before the 5-leaf stage of corn improves activity compared to the triazine alone. While these treatments don't kill the shattercane, they set it back, allowing the corn to get ahead of the cane. This sets the stage for effective control with cultivation.

Algae and Moss Control in Water and Stock Tanks

With warmer weather, moss and algae will again make their appearance in plastic nurse tanks used to hold water supplies for spraying operations. Control is simple and inexpensive.

New Registrations
