| dc.description.abstract | The investigation on gall formers and their management in chilli cv. Byadgi Dabbi was conducted at the Horticulture Research and Extension Centre (HREC), Haveri (Devihosur), University of Horticultural Sciences, Bagalkot, during the year 2016-17. Survey conducted in three major growing districts of Karnataka viz., Haveri, Dharwad and Gadag district revealed that Shiggoan taluk of Haveri district recorded highest gall formers incidence compared to other taluks. During the study it was found that incidence of gall formers highest in July transplanted crop compared to August transplanted crop. Screening of chilli germplasm for resistance to gall midge revealed that, out of 120 chilli germplasm only 22 germplasm were moderately susceptible (6-10 %) including Byadgi kaddi as check, remaining 98 germplasm including Byadgi dabbi as check showed susceptible reaction (11 - 25%) to gall midge incidence. None of the germplasm found highly resistant (No damage), resistant (<1%), moderately resistant (1 – 5%) and highly susceptible (>25%) to gall midge incidence. Among the various management practices against chilli gall formers, T2 (Neem cake @ 2.5 q/ha + Azadirachtin 10000 ppm @ 1 ml/l) registered its superiority over rest of the treatments. Next best treatments in the order of efficacy were T4 (Neem cake @ 2.5 q/ha + Diafenthiuron 50 WP @ 0.75 g/l), T5 (Neem cake @ 2.5 q/ha + Imidacloprid 200 SL @ 0.25 ml/l) and T3 (Neem cake @ 2.5 q/ha + Profenofos 50 EC @ 2 ml/l). Incorporation of neem cake @ 2.5 q/ ha at the time of transplanting followed by spraying of Azadirachtin 10000 ppm @ 1 ml/ l coinciding with peak flower bud initiation has recorded lowest gall formers incidence, highest dry chilli yield of 7.88 q per ha and highest B:C ratio of 3.02 can be recommend as effective and eco- friendly component for the management of chilli gall formers. | en_US |
