Regulatory/Toxicology

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.
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).
