- In
puddled drum seeded wet rice, pre-emergence application of Pretilachlor 0.75 kg
ha-1 on 8 DAS followed byrotary
weeding on 20 and 40 DAS could be a effective weed management practice which
significantly recorded the least weed density, weed dry matter and highest weed
control efficiency at 15, 30 and 45 DAS, higher growth and yield attributes,
and grain and straw yield and economics.
- Pre-emergence application of bensulfuron methyl and pretilachlor
commercial mixture (Londax Power) 6.6 GR @ 660 g a.i/haon 3 DAT
followed by one physical measures of weed control either power weeder weeding
or hand weeding on 35 DAT can be recommended as a effective weed management
practice for machine transplanted rice.
- Early post
emergence application of bispyribac sodium @ 25 g a.i. /ha on 20 DAS + hand
weeding on 40 DAS can be recommended as a effective weed management practice
for direct seeded aerobic rice.
- Application of
alachlor @ 1.5 kg a.i /ha with one hand weeding on 30 DAS to maize is a
desirable weed management practice for reducing the weed growth, realizing
higher grain yield and economic return.
- Pre-emergence
application of imazethapyr @ 0.1 kg a.i. /ha at 3 DAS spray followed by either
post-emergence application of Quizalofop-ethyl @ 0.1 kg a.i /ha at 30 DAS as
spray or hand weeding at 30 DAS can be recommended as an effective weed
management practice to irrigated greengram.
