Differential sensitivity of two common groundsel biotypes (Senecio vulgaris L.) to several s-triazine herbicides

Creator:

Radosevich, Steven R.

Abstract:

Studies were initiated to determine the response of two common groundsel biotypes (Senecio vulgaris L. ) to several s-triazine herbicides. Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine (simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)- s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys- triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine (prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio- s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6- methylthio-s-triazine (prometryne). One biotype was much more susceptible than the...

The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...
