e0“weed management in transplanted rice during Rabi 2011–12 at Tamil Nadu Agricultural University, Coimbatore”
e3“In main field among the different treatments early post emergence (EPOE) application of Bensulfuron methyl+ pretilachloar (6.6 GR) at 0.06+0.60 kg/ha recorded significantly higher grain yield (6450 kg ha−1), straw yield (8614 kg ha−1) through better weed control efficiency as indicated by lower weed density (4.3, 5.5 and 4.6 m−2 at 20, 40 and 60 DAT), reduced weed dry matter (2.2, 3.4 and 3.0 g m−2 at 20, 40 and 60 DAT) and higher weed control efficiency (80.6, 83.2 and 85.0% at 20, 40 and 60 DAT) followed by PE application of Pretilachlor at 0.75 a.i. Kg ha−1 + HW at 40 DAT other treatments”

Other claims from this paper (15)
- Intervention effect Pre-plant glyphosate at 0.75 kg a.i. ha-1 gave higher mean grain yield than no glyphosate application.
- Intervention effect Pre-plant glyphosate lowered weed density in transplanted rice compared with no glyphosate application.
- Intervention effect Pre-plant glyphosate lowered weed dry weight in transplanted rice compared with no glyphosate application.
- Intervention effect Pre-plant glyphosate gave higher weed control efficiency in transplanted rice than no glyphosate application.
- Intervention effect Pre-plant glyphosate eliminated most existing vegetation in the field.
- Intervention effect Pre-plant glyphosate prevented weed establishment in the field.
- Intervention effect EPOE application of Bensulfuron methyl plus pretilachlor significantly increased grain yield of transplanted rice compared with other treatments in the main field.
- Intervention effect EPOE Bensulfuron methyl plus pretilachlor increased straw yield of transplanted rice compared with other treatments in the main field.
- Intervention effect EPOE Bensulfuron methyl plus pretilachlor reduced weed dry matter in transplanted rice compared with other treatments.
- Intervention effect EPOE Bensulfuron methyl plus pretilachlor gave higher weed control efficiency in transplanted rice compared with other treatments.
- Mechanism Better control of pre-emerged and emerging weeds by EPOE Bensulfuron methyl plus pretilachlor is explained by its high activity against broad-leaved weeds and sedges.
- Intervention effect Pre-plant glyphosate gave the highest net return in transplanted rice compared with no glyphosate application.
- Intervention effect EPOE Bensulfuron methyl plus pretilachlor at 10 DAT gave higher gross returns than the other herbicides.
- Intervention effect EPOE Bensulfuron methyl plus pretilachlor at 10 DAT gave higher net return than the other herbicides.
- Intervention effect EPOE Bensulfuron methyl plus pretilachlor at 10 DAT gave a higher benefit-cost ratio (2.19) than the other herbicides.
