Mechanism of action
Pendimethalin absorbed by roots and plantlets restrains cell division and growth in meristems of sensitive weeds. Treated weeds perish soon after emergence or after sprouts crop out. Emergence itself is not inhibited.
Protective period
Depending on soil and climatic conditions - 8 to 10 weeks, throughout the vegetation period virtually.
Speed of action
Weeds die at the emergence stage. Sprouts die in 3 or 4 days.
Range of inhibited weeds
Annual grass and dicotyledonous weeds
Sensitive species: speedwell (species), pepper plant (species), charlock, bur grass, satin flower, common orach, copper rose, pigweed (species), loose silky bent, rough-stalked bluegrass, field scorpion grass, sow thistle (species), caseweed, field chamomile, wild radish, mayweed, sorgho (species), field pansy, foxtail (species), amaranth (species).
Moderately sensitive species: common fumitory, velvetleaf, foxtail grass, houndsberry, catch weed, crabgrass, day-nettle.
