Weed Control in Direct Seeded Rice Using Selected Herbicides
Man, Azmi (1984) Weed Control in Direct Seeded Rice Using Selected Herbicides. Masters thesis, Universiti Pertanian Malaysia.
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.
