Chemical weed management in maize using pre and post emergence herbicides

Abstract

A field experiment was conducted during kharif 2018-19 College of Agriculture, Latur to find out the effective herbicides for control of weeds in maize (Zea mays L.). The experiment comprises of ten treatment combinations and were compared with weed free and weedy check and laid out in randomized block design and replicated three times. Application of pendimethalin 1000 g a.i. ha-1 (PE) fb 2,4-D amine 1000 g a.i. ha-1 (PoE) was significantly superior in reducing weed density and dry weight of weeds. Weed free check, pendimethalin 1000 g a.i. ha-1 (PE) fb 2,4-D amine 1000 g a.i ha-1. (PoE), pendimethalin 1000 g a.i. ha-1 (PE) fb tembotrione 120 g a.i. ha-1 (30 DAS) and atrazine 1000 g a.i. ha-1 (PE) fb 2,4-D amine 1000 g a.i. ha-1 (PoE) registered 6335, 6099, 5549 and 5230 kg ha-1 kernel yield respectively as against the seed yield of weedy check, 2737 kg ha-1.
