Mancozeb Label Updates

Bob Mulrooney, Extension Plant Pathologist; bobmul@udel.edu

Good news on the fungicide front. Tolerances were established for mancozeb to replace some of the uses that maneb was labeled for. Maneb is no longer being manufactured. This has led to the first labels of mancozeb for use on broccoli, peppers, cabbage and leaf and head lettuce. Manzate Pro-Stick from UPI has a supplemental label for these uses, pending state approvals. I am sure the other manufacturers of mancozeb will have labels shortly. See the linked label for details: http://agdev.anr.udel.edu/weeklycropupdate/wp-content/uploads/2011/04/ManazteProStickVegSupplement.pdf. This label expansion was needed especially for control of anthracnose on peppers. These additions are not in the 2011 Commercial Vegetable Recommendations so you need to be aware of that.
