Abstract: The experiment on the ‘Integrated management of coconut eriophyid mite Aceria guerreronis (Keifer) (Acarina: Eriophyidae)’ was conducted during 2014-2016 at the farm of Asond block, Central Experimental Station, Wakawali, Dr. B. S. K. K. V., Dapoli. During August 2014, November 2014 and February 2015 the treatment, spraying with azadirachtin1 1 per cent @ 4 ml/litre of water + recommended dose of fertilizers (T2) was significant and showed lowest 40.00, 30.22 20.33 per cent eriophyid mite infestation respectively. During May 2015, the treatment T6 was found significant and showed 22.85 per cent infestation. During August 2015, the treatment T1 was found significant by recording 11.74 per cent infestation followed by T6. During November 2015, T6 was found significant and recorded 9.02 per cent infestation. During February 2016 T2 showed significant reduction in mite infestation up to 7.73 per cent. The pooled mean of period 2014-2016 revealed that, during May the treatment T6 was found to be significant by showing 38.88 per cent infestation. During August, the treatment T1 was significant by showing 27.71 per cent infestation. During November, T6 was found significant and showed 20.21 per cent eriophyid mite infestation. In February, T2 was found significant which recorded 14.03 per cent eriophyid mite infestation followed by T6, T1 and application of recommended dose of fertilizers and azadirachtin through briquettes (T5). During February 2016, same results were obtained, the treatment T2 was significant by showing 7.73 per cent infestation. Overall results of field trial indicated that treatment T6 was best treatment followed by T2, T1, T3, T8, T5, T7 and T4. The per cent grade wise infestation was also observed minimum or found to be almost gradually reduced in same treatments during both years.
