Weed Control in Direct Seeded Rice Using Selected Herbicides.
Masters thesis, Universiti Pertanian Malaysia.
Abstract
Selected herbicides for the control of weeds in direct
seeded rice were studied. The phytotoxicity of the herbicides,
2, 4-D amine, 2, 4-DIBE-butachlor, butachlor, benthiocarb and molinate
were evaluated in two studies using petri dishes and plastic pots.
A field study was also carried out to determine the efficacy of weed
control of 2, 4-DIBE-butachlor, butachlor and molinate.
2, 4-D amine and benthiocarb were found to behighly
phytotoxic when applied as a preemergent and as an early postemergent. Molinate was safe to apply as a preemergent. All the
herbicides evaluated were more toxic when applied during the early
postemergent period 14 days after sowing than when applied later at
35 days after sowing.
