9.  Current EPA registration for crop and non crop (ornamentals) uses.  CA non crop label only (MOI will submit crop label by the end of 2007).  More targets will be added (e.g. tomato, turf).  All other crops and diseases are opportunities for IR-4 priorities.  MOI is working on an organic formulation. Regulatory/Toxicology

10. Potential IR-4 Projects  Test Milsana ® as part of IPM programs in ornamentals, vegetables, fruit, vines (Botrytis, mildews, bacterial diseases. Other diseases ?  Test Milsana ® on turf diseases.  Test efficacy against other pathogens, such as oomycetes (Phytophthora spp. and downy mildew).
