Abstract

A study was conducted to determine the resistance of OnDuty herbicide in paddy soil with different concentrations by using a broadleaf plant, Brassica juncea. The herbicide was used in the Clearfield® Production System that was adopted in Malaysia to overcome problems mainly caused by weedy rice. Evaluation of herbicide half-life was based on bioassay technique with different concentrations, i.e 0% (control), 50% (half dose), 100% (recommended dose) and 200% (double dose). The study was done in three replicates and followed the Complete Randomized Block Design (CRBD). Results showed that there was a correlation between the amount of herbicide doses and degradation period. The highest half-life value was shown by root inhibition in the double dose concentration of 33 days half-life, followed by the recommended dose with 23 days half-life. Meanwhile, the half dose treatment indicated a half-life value of 17 days for root and 11 days for shoot. Therefore, application of herbicides should follow the recommended dose as the degradation period will not be too long, hence providing maximum effectiveness of the herbicide to overcome weed infestation problems.
