Abstract

Metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one], when applied pretransplant at 0.28 kg ai/ha, killed peppers (Capsicum annuum L.) that were transplanted bare root or in plugs. Activated carbon applied at 1 g/plant effectively reduced injury of such peppers in soils treated with up to 0.56 kg ai/ha metribuzin. The increase in crop tolerance to metribuzin was dependent on the amount of activated carbon added. The level of crop protection for plug transplants depended on the amount of activated carbon per plant rather than on the percentage in the greenhouse mix by dry weight. One gram was required to protect plug transplants grown in cells that held 10 or 20 g of greenhouse mix.
