Studies were conducted at Sugarcane Research Station, Vuyyuru to know the effect of meteorological factors and time of planting on the incidence of early shoot borer, Chilo infuscatellus Snell in Sugarcane. Three varieties viz., 99V30, 2000V59 and 2003V46 were planted at fortnight intervals from January to April. The percent incidence of shoot borer was recorded weekly starting from 3rd week after planting to 18th week in the three varieties in all the eight plantings. The corresponding meteorological data were also recorded. Correlation co efficient of the variety and time of planting, the percent shoot borer incidence recorded at weekly intervals showed positive correlation with max temp, min temp and sunshine hours and negative correlation with was worked out. Irrespective forenoon and afternoon relative humidity and rainfall for the current week and preceding two weeks.
