Figure 1 Weed Susceptibility, application timing and water management regimes for California rice herbicides.  In the case of watergrass, resistance is strongest with late watergrass (“mimic”); resistance to ALS inhibitors may or may not involve all herbicides in that group.

Figure 2.  Weed susceptibility, application timing and water management regimes for tank-mixed herbicides in California rice. In the case of watergrass, resistance is strongest with late watergrass (“mimic”); resistance to ALS inhibitors may or may not involve all herbicides in that group.

Figure 3.  Weed susceptibility, application timing and water management regimes for herbicide sequences with Regiment, Bolero, and Propanil. In the case of watergrass, resistance is strongest with late watergrass (“mimic”); resistance to ALS inhibitors may or may not involve all herbicides in that group.

Figure 4.  Weed susceptibility, application timing and water management regimes for herbicide sequences with Cerano in California rice.  In the case of watergrass, resistance is strongest with late watergrass (“mimic”); resistance to ALS inhibitors may or may not involve all herbicides in that group.

Figure 5.  Weed susceptibility, application timing and water management regimes for herbicide sequences with Clincher in California rice.  In the case of watergrass, resistance is strongest with late watergrass (“mimic”); resistance to ALS inhibitors may or may not involve all herbicides in that group.

Figure 6.  Weed susceptibility, application timing and water management regimes for herbicide sequences with Granite. In the case of watergrass, resistance is strongest with late watergrass (“mimic”); resistance to ALS inhibitors may or may not involve all herbicides in that group.
