The registrant has submitted a required study (MRID No. 468252*Oi) for review forthe subject product, Thidiazuron Technical. Because the sUbject product is a manufacturing-use product. the registrant needed to submit a missing watersolubilitystudy (reference guideline 830.7840) for the subject product. The technical review branch (TRB) has been asked to review the submitted data for acceptability. SUMMARY OF FINDINGS, 1. The registrant has submitted a GLP Compliance Statement (dated 2t/APR/2006 and OifMAYl2oo6) for the submitted study. 2. The water solubility of the subject product, Thidiazuron Technical, averages 0.0082 9 / L at**20~C.** CONCLUSIONS: TRB has reviewed the submitted studyand has concluded: t. The submitted study corresponding to reference guideline 830.7840 (Water Solubility) satisfied the corresponding requirements of 40CFR§158.190, for the water solubility data requirements.

# NON- FEE

The registrant has submitted product chemistry data for storage stability and corrosion characteristics in supportoftheregistration applicationfortheproposedmanufacturing-useproduct.Theproductchemistrydata has been submitted underMRfD No. 458328·01. Theproposed manufacturing-use product hasThidiazuron (Reg. No. 51036-402,98.3%)as its active ingredient. TRB hasbeen askedto evaluate the product chemistry data submitted forthe proposed manufacturing-use product. SUMMARY OF FINDINGS 1. The end-use product contains Thidiazuron (Reg, No. 51036-402, 98.3%) as its active ingredient with a label cfaim of98.3%, 2. Thedatasubmitted correspondingt0830Series SubgroupA (product identity, composition, anatysis)were alf previously accepted. 3. The data submitted corresponding to 830 Series Subgroup B (physical-chemical properties) were previousty accepted\ except for the solubifity in water (830.7840), storage stabifity (830,6317) and corrosion characteristics (830.6320). 4. Thedata submitted forthe storage stab'lIity (830.6317) requ"lrements werefortime zero, three months, 6 months and 12 months, [MRtD No. 458328-01] 5. The data submitted in referenceto guidetine830.6320 (corrosion characteristics)were cotlected by visual inspection ofthe packaging in conjunction with the storage stabifity study. CONCLUStONS: The TR8 has reviewed the product chemistry data submitted for the proposed technical product and has concluded that: 1. The product chemistry datasubmitted corresponding to 830 Series SubgroupA were previously accepted. 2. The product chemistry data submitted corresponding 830 Series Subgroup 8 (physical/chemical properties) were previously accepted\ except for the water solubility (830.7840) and those pertaining to storage stabifity (830.6317) and corrosion characteristics (830.6320).
