Abstract:

Mites are noxious pests infesting the garlic crop leading to significant yield loss. Several synthetic chemicals have been used over several decades; however, the extensive use of the chemicals has deleterious effects on both human health and the environment. Hence, a field experiment was conducted at the College of Horticulture, Bidar to evaluate the different non-chemical traditional methods against the garlic mite complex during 2020-21. Among the different treatments, sequential water spray –NSKE 5% at an interval of 24 hrs registered the lowest mean carmine spider mite population after the first spray (16.57/sq. cm of leaf) and second spray (15.82/ sq. cm of leaf). Further, it also recorded the highest mite population reduction over control to an extent of 64.90% and 65.98%, after the first and second spray, respectively. The sequential water spray -Pongamia seed extract 3% was next best with 61.99 and 63.01 percent reduction over control after the first and second spray, respectively. Similar results were obtained during 2021-22. The sequential water spray – NSKE 5% also proved to be best against bulb mites as it recorded the lowest lacerations on the garlic cloves (25.36 and 27.15%) with the highest reduction in laceration (51.57 and 51.21%) and the highest yield (27.00q/ha and 25.80q/ha) during 2020-21 and 2021-22, respectively.
