13278 D PYRIPROXYFEN ( VALENT ) LETTUCE (GH) ( 04-16A = LEAFY GREENS SUBGROUP ) RESEARCHABLE, RESIDUE & E/CS DATA NEEDED

Reduced Risk Status: THIS AI HAS BEEN CLASSIFIED AS RR FOR ONE OR MORE FOOD USES.
IPM Compatibility: PER REQUESTOR VERY GOOD FIT; THE NATURAL ENEMIES USED IN LETTUCE ARE PREDOMINATELY PARASITIC WASPS AND THIS PESTICIDE (AN IGR) WORKS WELL WITH THE NATURAL ENEMIES
Reasons for need: SHOREFLY, FUNGUS GNATS, POSSIBLY APHIDS AND WHITEFLY AND THRIPS; FUNGUS GNATS AND SHORE FLY ARE CHALLENGING IN GREENHOUSE LETTUCE PRODUCTION BECAUSE OF THE HIGH LEVEL OF MOISTURE PRESENT. AS OFTEN LETTUCE IS SOLD WITH THE PLUG OR ROOT BALL, IT IS A RISK THAT FUNGUS GNATS AND SHORE FLY COULD END UP IN THE FINAL PRODUCT SHIPPED TO CUSTOMERS. ADDITIONALLY, AS WE HAVE SUPPORT FROM VALENT CANADA FOR USE IN CANADA, AND SO THEY HAVE THE NEEDED EFFICACY AND SAFETY DATA, WE WOULD ONLY NEED A B LEVEL OF SUPPORT FROM THE IR-4 TO SECURE USE FOR OUR US GROWERS.
