%✓ �1 "EXHIBIT D" HERBICIDE TREATMENT TABLE WEED MANAGEMENT AND CONTROL (Continued) Herbicide Amount/Acre P.H.I.+ (commercial name) (days) ------------------------------------------------------------------- D. TRICLOPYR (Grandstand CA) 0.25-0.375 lb a.i. 60 COMMENTS: Apply by air or ground when rice is in the 4-leaf to well-tillered stages. weeds should be actively growing at time of treatment and well-emerged above the water surface. Consult your county agricultural commissioner for current water management restrictions. Do not raise water levels for 24 hours after application or drain field for any reason until 20 days after application. If the water level is dropped to expose weeds before treatment, do not raise the water level for at least 48 fours after application. Do not make more than 2 applications/season and allow at least 20 days between application. See label for other restrictions. E. FENOXA.PROP-ETHYL (Whip) IEC 0.125 lb a.i. (1-2 tiller stage) 80 0.15 lb a.i. ( 2-4 tiller stage) 0.2 lb a.i. (before panicle initiation) COMMENTS: Apply after rice plant has one well-developed tiller up to panicle initiation. Earlier applications provide better control. Watergrass and sprangletop should be actively growing; if weeds are drought-stressed, reduced control may result. Consult your county agricultural commissioner for information on minimizing off-site water movement of fenoxaprop residues. Lower water so that 70% of grass foliage is exposed. Do not increase water level for at least 3 days. After 3 .days, slowly bring water to a normal depth. See label for other restrictions. F. SENSULFURON s0 (Londax) 60DF 0.06 lb a.i. COMMENTS: Apply at 2- to 4-leaf stage when rice roots are well anchored into the soil but broadleaf weeds are relatively small. Application can be made up to the 6-leaf stage if necessary, but competition from broadleaf weeds increases the longer application is delayed. Always alternate with herbicides of different chemistries to reduce the development of weed resistance. Do not use in fields known to have resistant weeds. Do not use on wild rice. G. COPPER SULFATE PENTAHYDRATE (Copper Sulfate 10-15 lb a.i. Instant) COMMENTS: For control of algae. Apply higher rate in deeper water (6 inches or greater) . + Preharvest interval. Do not apply within this many days of harvest. * Permit required from county agricultural commissioner for purchase or use.
