Hexazinone Persistence in Two Different Types of Soils
Two identical studies were conducted to determine soil persistence of hexazinone (3-cyclohexyl-6-(dimehtylamino)-l-methyl-l,3,5-triazie-2,4(1H,3H)-dione) under actual field conditions. Hexazinone (Velpar 9OW), at 2 and 4 kg/ha, was applied with a tractormound boom sprayer to the sites at Opelika, Alabama (Pacolet clay) and Auburn, Alabama (Uchee loamy sand) in the Spring of 1978. The experiments were laid out in a randcmized complete-block design with 3 replications. Each plot was 7m x 14m and separated by 1 meter buffer zone.
