Pulsar is a herbicide belonging to the imidazoline group. It is absorbed through weed foliage and causes an immediate cessation of growth. The treated weeds gradually turn yellow and eventually die.
For best results, Pulsar should be applied to young weeds, as its efficacy is greatest at the early growth stages. Applications are recommended up to the 3-4 leaf stage of the weeds.
Following activation by irrigation or rainfall of at least 20 mm, Pulsar also provides residual pre-emergence control of some of the weeds listed on the product label.
Pulsar may cause temporary growth suppression in crops such as beans, peas, clover, and vetch. However, crop growth subsequently recovers, and this temporary effect does not reduce yield.
