Conclusion
Based on the present findings, it can be concluded that application of PoE herbicide Mesotrione
2.27% w/w + Atrazine 22.7% w/w SC @ 875 g a.i.ha -1 at 20-25 DAS or PE Atrazine @ 1 kg
a.i. ha -1 + one hand weeding at 20 DAS or PoE Tembotrione 34.4% SC 120g a.i.ha -1 at 20-25
DAS was found profitable, cost effective and one of the good alternative options for hand
weeding.
