Abstract

Several methods were used to overcome herbicide phytotoxicity to upland rice (Oryza sativa L., ‘IR8′). Seed pelleting with activated carbon and band application of activated carbon slurry over the rice seed were ineffective in reducing the toxicity of chloramben (3-amino-2,5-dichlorobenzoic acid) and atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] to upland rice. In contrast, a 2.5-cm layer of activated carbon and vermiculite mixture (1:1) placed over the rice seed was effective in overcoming the toxicity of these herbicides. Deep sowing (3.0 to 4.5 cm) of rice seed was adequate in protecting upland rice from herbicides which are toxic to direct seeded, flooded rice but are not toxic to transplanted rice. The degree of protection from deep sowing, however, was determined by site of uptake, herbicide adsorption by soil, leaching, and inherent toxicity of the herbicides to rice seedlings.
