ABSTRACT
A field experiment was conducted on black soil at Main Agricultural Research Station, Dharwad during kharif season of 2015 to study effect of tank mixtures on weed control in maize. The treatments consisted of sole application of herbicides viz., atrazine, 2,4-D, tembotrione, topramezone in comparison with their tank mixtures and standard check of recommended weed management practice- atrazine 1.25 kg ha-1 (PRE) + 1HW + 1IC, sequential application-atrazine 1kg ha-1 (PRE) fb 2,4-D 500 g ha-1,Weed free and weedy check. Spraying was done at 16 DAS. The results of the experiment shows that among tank mixtures, topramezone + 2,4-D recorded significantly lower weed density, Weed dry matter, higher grain yield next to recommended weed management practices. Herbicide mixtures performed better than sole applications.
Key words: Early post emergent herbicides, Topramezone, Tembotrione, Tank mixture, Weed density, Weed dry weight.
