Abstract:

To find out the efficacy of Pinoxaden alone and in combination with Metsulfuron and Carfentrazone against complex weed flora in barley (Hordeum vulgare L.), an experiment was conducted at CCS Haryana Agricultural University, Hisar during rabi 2013-14. The experiment was arranged in randomized block design and was replicated thrice with eleven weed control treatments comprised of individual application of Pinoxaden @ 30, 40 and 50 g ha-1, tank mixture of Pinoxaden @ 40 g ha-1 with Metsulfosulfuron @ 4 g ha-1 and Carfentrazone @ 20 g ha-1, Pinoxaden fb Metsulfuron (40+4 g ha-1), individual application of Isoproturon @ 1000 g ha-1, tank mixture of Isoproturon @ 750 g ha-1 with 2,4-D @ 500 g ha-1 and Metsulfuron @ 4 g ha-1, weedy check and weed free. Result of the experiment revealed that Pinoxaden @ 50 g ha-1 was very efficient against grassy weeds without any phytotoxic effect, but is ineffective against broad-leaf weeds. Tank mix application of Pinoxaden @ 40 g ha-1 with broad-leaved herbicides i.e. Metsulfuron @ 4 g ha-1 and Carfentrazone @ 20 g ha-1 and Pinoxaden fb Metsulfuron (40+4 g ha-1) proved effective in controlling mixed weed flora and total dry weight of weeds at 60 and 90 days after sowing. Pinoxaden fb Metsulfuron @ 40+4 g ha-1 produced significantly higher grain yield than individual application of different herbicides and weedy check but statistically at par with tank mixture of Pinoxaden @ 40 g ha-1 with Metsulfuron @ 4 g ha-1 and Carfentrazone @ 20 g ha-1. Presence of weeds throughout the growing season brought about 24% reductions in grain yield as compared to weed free treatment. The increase in grain yield of barley due to application of Pinoxaden @ 40 g ha-1 fb Metsulfuron @ 4g ha-1 was 22.5 % over weedy check. Increased grain yield in herbicide mixture of Pinoxaden @ 40 g ha-1 with Metsulfuron @ 4 g ha-1 and Carfentrazone @ 20 g ha-1, Pinoxaden @ 40 g ha-1 fb by Metsulfuron @ 4g ha-1 could be ascribed to poor weed growth, weed dry matter and more number of grains earhead-1 and test weight when compared with alone application of herbicides and weedy check treatment. Higher weed control efficiency with lower weed index was recorded under Pinoxaden fb Metsulfuron (40+4 g ha-1) applied treatment.
