06607 B PENDIMETHALIN ( BASF,UPI ) FIG ( 23B = TROPICAL AND SUBTROPICAL, MEDIUM TO LARGE FRUIT, EDIBLE PEEL SUBGROUP ) RESEARCHABLE, RESIDUE & E/CS DATA NEEDED

Reduced Risk Status:
IPM Compatibility: PER WSR 2016 NOMINATION COMMENT: GOOD IPM FIT; WOULD PROVIDE ANOTHER USEFUL PRODUCT AT A REASONABLE COST:09/16; FROM WSR 2017 NOMINATION: VERY GOOD IPM FIT; PENDIMETHALIN IS USED AS A PREEMERGENCE HERBICIDE IN TREE CROPS, PRIMARILY TARGETING GRASSES AND SOME SMALL-SEEDED BROADLEAF WEEDS; FIG GROWERS HAVE A LIMITED NUMBER OF PREEMERGENCE MATERIALS AND INSTEAD RELY VERY HEAVILY ON REPEATED APPLICATIONS OF GLYPHOSATE, PARAQUAT, AND OTHER FOLIAR-APPLIED HERBICIDES; BY INCORPORATING AN EFFECTIVE PRE MATERIAL INTO THE INTEGRATED PEST MANAGEMENT PROGRAM FOR WEEDS, GROWERS WILL LIKELY REDUCE THE NUMBER OF POST APPLICATION REQUIRED FOR ACCEPTABLE SEASON-LONG WEED CONTROL; FURTHER, PENDIMETHALIN CAN CONTROL GLYPHOSATE-RESISTANT GRASSES SUCH AS JUNGLERICE AND SUPPRESSES MANY MEMBERS OF THE PIGWEED SPECIES COMPLEX; PENDIMETHALIN IS APPLIED TO CLEAN SOIL AND INCORPORATED WITH RAINFALL OR IRRIGATION; BECAUSE IT IS EXTREMELY TIGHTLY BOUND TO SOIL, PENDIMETHALIN IS CONSIDERED VIRTUALLY IMMOBILE AND NOT A LEACHING HAZARD; ALTHOUGH MOST CALIFORNIA FIGS ARE GROWN IN RELATIVELY FLAT FIELDS SO WATER EROSION IS A RELATIVELY MINOR ISSUE, THE HERBICIDE HANDBOOK ALSO REPORTS THAT PENDIMETHALIN ON SOIL PARTICLES WASHED OFF FIELDS GENERALLY REMAINS BOUND TO SEDIMENT AND IS UNAVAILABLE TO AQUATIC ORGANISMS; FINALLY, THE MODERN AQUEOUS SUSPENSION FORMULATION OF PENDIMETHALIN (EG PROWL H2O) HAS VERY LOW FRACTIONS OF VOLATILE ORGANIC COMPOUNDS COMPARED TO THE OLDER EC FORMULATIONS AND PRESENT SUBSTANTIALLY LOWER AIR QUALITY RISKS IN THE OZONE NON-ATTAINMENT REGIONS OF THE CENTRAL VALLEY OF CALIFORNIA
