Try to avoid applying pesticides with the same mode of action to more than one generation of the pest per cycle. weed control and crop desiccation prior to harvest. Repeated use of herbicides with the same site of action can result in herbicide-resistant weed populations. or more modes of action. FRAC works to prolong the effectiveness of fungicides liable to encounter resistance problems and to limit crop losses should resistance occur. A simple conceptual diagram, depicting pathways from sources to impairments, related to herbicides. When labels permit, make two (2) applications of a product or tank mix in sequence, then rotate to products with different modes of action to improve coverage on target life stages of the pest. These time-lapse photography videos show the effects of various herbicides on plants. the resistant individuals will multiply and become the dominant weeds in the field, 1998), resulting in additive or synergistic effects.
