3 Fungicide Overview Source: Extract from giant knotweed, Reynoutria sachalinensis (REYSA). For foliar diseases including powdery mildew, downy mildew, Botrytis, Alternaria, Xanthomonas and others Regalia acts on the treated plant and not on the disease organism

4 LABEL UPDATE REGARDING Line of Products

5 A USER S GUIDE TO THE PRODUCT LINE Regalia SC = 5% a. i. Regalia SC is the formulation most similar to Milsana and is no longer sold in the United States. Regalia SC was not NOP compliant. Regalia (MBI-10605) = 5% a.i., is NOP compliant and OMRI listed. Regalia received California registration in January 2010 and is sold nationwide. Regalia MAXX (MBI ) = 20% a.i.. EPA registered in April 2010, MAXX is being developed for markets outside the U.S. and may replace Regalia at some future point in the U.S.

6 Regalia (MBI-10605) label changes Numerous additional crops and diseases For conventional and organic production NOP/OMRI compliant REI = 4 hours, PHI = 0 days. CAUTION statement No limit on number of applications Expanded aerial and ground application instructions Greenhouse Use Labeled for greenhouse use on edible After crops. rinse Registered and sold in most states in the U.S.

13 Where do we go from here? We continue to conduct a rigorous laboratory and greenhouse program to identify combinations of Regalia and conventional chemistries to identify synergistic combinations to evaluate in the field against specific diseases

14 We continue to investigate compatibility and synergies between Regalia and other chemistries such as DMI s, strobilurins, quinoxyfen, etc. Untreated chardonnay Regalia alternated with Quintec on a 14 day schedule

17 Since launching the new formulation of Regalia in January 2010, we have seen significant adoption of Regalia by growers in several key production areas in the U.S. and Regalia is being registered in numerous other countries throughout h the world. The IR4 program has been a key stakeholder in the development of this active ingredient for over a decade. THANK YOU!
