Abstract
Field experiment was conducted at sebbakkam
village, veppur taluk of cuddalore District during the year 2023-24 and 2024-25
to study the evaluation of bio-efficacy for post emergence herbicide 2,4-D 95%
SP against weed flora in sugarcane. The experiment comprised of seven
treatments laid out in randomized complete block design replicated thrice. The
treatment comprised of 2, 4-D Sodium salt 95% SP @ 2210 g a.i. ha-1 (T1),
2, 4-D Sodium salt 95% SP @ 2600 g a.i. ha-1 (T2), 2, 4-D
Sodium salt 95% SP @ 2990 g a.i. ha-1 (T3), Diuron 80% WP
@ 3200 g a.i. ha-1 (T4), Metsulfuron methyl 20% WP @ 6 g a.i.
ha-1 (T5), Hand Weeding on 30, 60 and 90 DAP(T6)
and Untreated control (T7). The results have been found that all the
weed control measure significantly reduce the weed density and weed bio mass,
at the same time effectively improves the crop growth and yield in comparison
to control. Among the various herbicidal treatments, application of 2, 4-D
Sodium salt 95% SP @ 2990 g a.i. ha-1 (T3) on 20 DAP has recorded
the lesser weed density and higher weed control efficiency. Additionally, it
has acquired the maximum growth attributes (plant height, tillers count,),
yield attributes (no. of millable cane, cane length, cane grith and individual
cane weight) and cane yield. This was on par with the application of 2, 4-D
Sodium salt 95% SP @ 2600 g a.i. ha-1 (T2). The next best
was application of 2, 4-D Sodium salt 95% SP @ 2210 g a.i. ha-1 (T1).
Hence it can be concluded that application of 2, 4-D Sodium salt 95% SP @ 2990 g
a.i. ha-1 (T3) holds immense potentiality to give higher
yield of sugarcane.
