Abstract

Field experiments were conducted at Krishi Vigyan Kendra, Sri Muktsar Sahib, Punjab, to find effectiveness of different insecticides against stem borer and leaf folder in rice and basmati rice. During Kharif 2014, Fame 480 SC (flubendiamide 39.35 %) @ 50 ml/ha, Dursban (chlorpyriphos 20% EC) @ 2500 ml/ha, Marktriazo (triazophos 40% EC) @ 875 ml/ha and Sutathion (triazophos 40 % EC) @ 875 ml/ha were tested along with untreated control in rice. All the insecticidal treatments were significantly superior to untreated control. Fame 480 SC @ 50 ml/ha was found most promising with minimum dead heart, white ear and leaf folder incidence. During, Kharif 2015, three different brands of fipronil 0.3 G (Mifpro-G, Mahveer GR, Regent) @ 15kg/ha, two brands of cartap hydrochloride 4 per cent G (Miftap, Nidan) @ 25 kg/ha were tested along with flubendiamide (Fame 480 SC) @ 50 ml/ha in basmati rice. The data on dead heart, white ear, leaf folder incidence, grain yield showed that all the insecticides effectively control the stem borer on basmati rice, but Fame 480 SC, Nidan and Miftap were comparatively more effective against leaf folder. Considering the efficacy data and very low dose (ha^-1), Fame 480 SC proved to be better option for management of two major pests of rice.

Abstract

Basmati rice is an important cash crop of India, being recognized at international level for its quality and aroma. Bakanae/foot rot disease is becoming a limiting factor in its cultivation in southwestern parts of Punjab. A survey was conducted during Kharif 2014 in different blocks of Sri Muktsar Sahib District of Punjab to acquaint with the factor affecting disease incidence. Disease was recorded in all the basmati growing fields and up to 10 per cent incidence was recorded on different aromatic rice cultivars. Pusa Basmati 1401 was observed more susceptible followed by Pusa Basmati 1121 and Pusa Basmati 1509. Basmati crop raised at recommended period showed lower disease incidence than early transplanted crop. Higher disease incidence was observed in fields where seed was purchased from private seed companies than seed from State Agricultural University. The recommended technology to manage this disease i.e. seed soaking in pesticides solution containing carbendazim 50 WP @ 0.2 per cent + Streptocycline 0.01 per cent (one g) for 12 hrs followed by seedling ischolar_main dip in carbendazim 50 WP (0.2%) for 6 hrs was demonstrated at selected farmers' field during Kharif 2015. The results showed that seed treatment with carbendazim @ 2.0 g/kg alone (farmers' practice) was not effective. The disease incidence in demonstrated plots was less as compared to farmers' practice. The grain yield and net returns were also higher in demonstrated plots.
