How does it work?


Primiera is absorbed through the leaves, shoots, and roots of weeds and then translocated throughout the plant. It inhibits an enzyme responsible for carotenoid biosynthesis which leads to bleaching and then death of the plant.

Application


When used post-emergence Primiera is most effective when applied to weeds up to the 8 leaf stage, typically 5 - 10 cm tall. To increase the spectrum of weed activity Primiera is best used in combination with 1 - 1.5L/ha of Flowable Atrazine 500 or 0.4 - 0.7kg/ha Nu-Trazine™ 900DF.
For optimal post emergence weed control, particularly against grass weeds such as summer grass, Primiera must be used in tank mixture with Bonza® at 0.5 - 1.0L/100L water.

Rainfastness


Providing the spray has dried on the foliage, light rain after spraying will not affect the results. Otherwise rain within three hours of treatment may reduce effectiveness.
