Abstract
Occurrence of foliar aphid infestation and yellow rust infection is often simultaneous in wheat growing areas of North-Western Plains Zone (NWPZ). Farmers usually apply insecticides and fungicides separately for their management. Combined application of pesticides can be practiced saving cost, time and labour. Hence, a study was conducted during 2014–15 and 2015–16 to determine efficacy of two insecticides, imidacloprid @ 100 ml/ha and thiamethoxam @ 50 ml/ha, and one fungicide, propiconazole @ 500ml/ha alone as well as in combinations using two spray volumes of 250 and 500 l against foliar aphid and strip rust. The aphid population during 2014–15 after 15 days of spraying was observed to be the least (2.5 aphids/earhead) in sole application of imidacloprid @ 100 ml/ha, while during 2015–16, the least population (1.9 aphids/earhead) was in combination treatment of propiconazole with thiamethoxam @ 50 ml/ha in 250 l of water. The strip rust severity in combination treatments was 5–10% as compared to 40–60% in control plots. Coccinellid population in combination treatments ranged from 13.0–19.6/plot as compared to 39.6–42.3/plot in control plots. The studies indicated that mixing of broad spectrum fungicide, propiconazole did not influence the efficacy of two insecticides against foliar aphid.
