Notes: The effect of planting date on the incidence and intensity of sugarcane scale insect (M. glomerata) was investigated in a field experiment conducted in Sirugamani, Tamil Nadu, India, with sugarcane cultivars CoC 671, CoSi 86071, Si 85124 and Si 85197 planted in December (pre-season), January, February (early season), March (mid-season), April, May, June (late season), July and August (special season). No detrashing was performed. Observations were recorded on the incidence (cane basis) and intensity (nodal basis) at 6, 9 months after planting and at harvest in 12 middle rows. Differences among the various times of planting and genotypes were significant in terms of scale incidence and intensity. The minimum incidence and intensity were recorded in June and July plantings and the maximum in December and January plantings in both plant and ratoon crops.
