| dc.description.abstract | The studies on Elite genotypes of chilli (Cv. Byadgi dabbi) against chilli pest complex and their management was conducted during the year 2016-17 at Horticulture Research and Extension Center, Devihosur (Haveri), University of Horticultural Sciences, Bagalkot. Among 70 genotypes screened against chilli pests, four genotypes viz., BDS-02, BDS-14, BDS-32, BDS-47 exhibited moderate resistance to thrips. Similarly, BDS - 01, BDS - 27, BDS - 41, BDS – 68 genotypes were identified as moderately resistant against mites. Further, 24 genotypes viz., showed moderately resistance to chilli fruit borer. None of the germplasm showed complete resistance to chilli pest complex. Evaluation of new molecules against chilli thrips revealed that thiamethoxam 25 WG @ 0.20 g/l recorded maximum yield (9.55 q ha-1) and B:C ratio (3.71). Similarly, spiromesifen 24 SC @ 1.0 ml/l was found to be significantly superior in suppressing chilli mite population by recording highest yield (11.94 q ha-1) and B:C ratio (4.23). Further, chlorantraniliprole 18.5 SC @ 0.20 ml/l registered more than 90.0 per cent reduction in chilli fruit borer damage with highest yield (11.74 q ha-1) and B:C ratio (4.40). Among the different modules evaluated against chilli pest compex, adaptable module comprising of i) growing one row of marigold (1:16) as a trap crop and two rows of maize as barrier crop, ii) application of neem cake @ 2.5 q ha-1, iii) root dip with imidacloprid 17.8 SL @ 0.5 ml/l for 30 minutes at the time of transplanting, iv) azadirachtin 10,000 ppm @ 1.0 ml/l + Lacanicillium lecanii (1x108 CFU/g) @ 5 g/l, v) thiamethoxam 25 WG @ 0.20 g/l vi) diafenthiuron 50 WP @ 1.0 g/l and vii Chlorantraniliprole 18.5 SC @ 0.2 ml/l proved to be quite effective against chilli pests and obtaining higher yield (11.84 q ha-1) and B:C ratio (3.29). Next best module was biointensive module-M1. Thus, both bio-intensive and adoptable modules have been considered to be a sound tool of IPM. | en_US |
