Notes:
Summary. Pigweed (Amaranthus sp.) control was not satisfactory where furrow irrigation was substituted for mechanical incorporation of nitralin or trifluralin on loam. Trifluralin concentrations in soil were twice as high after mechanical incorporation compared to furrow irrigation alone. In some instances, nitralin gave excellent pigweed control when rainfall occurred within 1 day after application. However, weed control was not consistent over a 3-year period. When herbicides were applied through a sprinkler irrigation system, chemicals were retained in the upper 5 cm of loamy sand and did not leach. However, herbicide distribution was not uniform due to irregular water movement by wind during application. Trifluralin did not control pigweed when applied and incorporated by sprinkler irrigation. Under the same conditions, nitralin gave good to excellent control.Incorporation de la nitraline et de la trifluraline par la pluie et par I'irrigation
