Item Evaluation of pesticides and biopesticides against the coconut eriophyid mite, Aceria guerreronis keifer under laboratory conditions(2010) Pushpa, V.; Nandihalli, B.S.Item Large scale demonstration of eco-friendly management of coconut eryophid mite, Aceria guerreronis (Keifer)(2010) Rafee, C.M.; Nandihalli, B.S.Item Management of coconut eriophyid mite, Aceria guerreronis Keifer through spraying and root feeding(2010) Pushpa, V.; Nandihalli, B.S.A field experiment was laid out in a randomized block design at Navalur, Dharwad, Karnataka to evolve effective spray schedule and root feeding against the coconut eriophyid mite, Aceria guerreronis Keifer. The experiment had nine treatments and six plants were selected for each treatment. Among the different schedules, the treatment consisting of root feeding for six times in a year at two months interval during (January, March, May, July, September and November) proved significantly superior in reducing the mite (both active stages and egg) population and recorded minimum number of damaged nuts.Item Management of coconut perianth mite, Aceria guerreronis (Keifer) through nutrition(2009) Lokesh, B.R.; Nandihalli, B.S.Investigation on impact of plant nutrition on population build up of coconut perianth mite, Aceria guerreronis (Keifer) was carried out at Navalur near Dharwad during 2007-08. Among the different nutrients applied to soil recommended dose of fertilizer (RDF) + full dose of borax + MgSO4 + gypsum + neem cake, RDF + half dose of borax + MgSO4 + gypsum + neem cake and RDF + borax were the most effective and significantly superior treatments by recording 42.10, 36.03 and 34.11 per cent reduction of mite over control. With respect to per cent damaged nuts and grade indices, RDF + full dose of borax + MgSO4 + gypsum + neem cake, RDF + MgSO4, RDF + half dose of borax + MgSO4 + gypsum + neem cake and RDF + gypsum were the effective treatments and recorded 19.29 to 34.06 per cent damaged nuts and 1.56 to 1.83 damage grading.Item Seasonal abundance and varietal reaction of coconut perianth mite, Aceria guerreronis Keifer in Dharwad area(2009) Girisha, R.C.; Nandihalli, B.S.Studies on seasonal abundance and varietal reaction of eriophyid mite was carried out during 2004-2005 in Dharwad area. Results on seasonal abundance indicated that the mite population occurred through out the year with variation during different seasons of the year. The mite population was high during April and May 2005. It started declining with the onset of rain during first fortnight of July 2005. By February 2005, the population started increasing when atmospheric temperature also started increasing. Damaged nuts were in the category of grade 3 and most of the coconut palms possessed more than 54 per cent damaged nuts. Results on varietal reaction of eriophyid mite indicated that Gangabondam recorded least number of mite population (28.96) and also recorded least damage grade, lowest percentage of damaged nuts with highest percentage of healthy nuts.Item Seasonal incidence of coconut perianth mite, Aceria guerrermis Keifer around Dharwad(2009) Pushpa, V.; Nandihalli, B.S.
