### SUBJECT: Clofentezine (125501) Typical Application Rate for Grapes to Support HED ' s Occupational Risk Assessment, DP 

### # 433503 

### FROM: AJ . C\ , Cynthia Doucoure, Environmental Protection Specialist (;**~** Science Information and Analysis Branch Biological and Economic Analysis Division (7503P) 

### THRU: Diann Sims,

### TO: Andy Ertman , Ri sk Manager Reviewer Registration Division (7505P) 

### SUMMARY Through this memo, BEAD is providing the typical application rate for grapes to support the refmement ofHED's occupational risk assessment. According to HED, there are occupational post-application cancer risk concerns for grapes (wine, table , and raisin) related to hand harvesting. Based on available Market Research Data, B EAD recommends using 0 .2 lb 

### ai./ A as the typical application rate for clofentezine use grapes to support refinement of the HED occupational risk assessment. 

### CLOFENTEZINE USAGE BEAD reviewed public and proprietary Market Research Data sources to obtain typical application ra te information for clofentezine use on grapes. BEAD found tha t, based on the Market Research Data, the overall typical application rate for clofentezine use on grapes is 0.2 lb a.i./A as shown in Table 1 below. BEAD compared the clofentezine typical application rates for grapes from the Market Research Data with the California Department of Pesticide Regulation (DPR) median application rates for clofentezine use on grapes and found that they are similar as shown below in Table 2 . B EAD also reviewed USDA National Agricultural Statistics Service Page 1 of3

### (NASS) data, which showed usage of clofentezine on wine grapes for the years 2009 and 2011 but the data was withheld to avoid disclosing data for individual farms. T bl 1 Cl £ t . U

### RECOMMENDATION Based on the available clofentezine typical/median application rate data from Market Research Data and California DPR, BEAD recommends using 0.2lb a.i./A as the typical application rate for clofentezine use on grapes to support refinement ofthe HEO occupational risk assessment.
