Abstract

A study on the seasonal incidence and management of harar borer Dichocrocis sp. was carried out at the College of Horticulture and Forestry, Neri, Hamirpur, Himachal Pradesh in 2018-19. Incidence started during the last week of May with two peaks, first peak was in the last week of July (77%) and the second peak (72%) was in the last week of September. The four insecticides viz. chlorantraniliprole 18.5 w/w, cyantraniliprole 10.26OD, fenvalerate 20EC, monocrotophos 36%EC and the biopesticide agniastra prepared using cow urine, reduced the infestation to <43%. Chlorantraniliprole 18.5 w/w @ 0.005% was the best reducing the infestation to 7.77% followed by cyantraniliprole 10.26OD @0.01% (9.99%) and fenvalerate 20EC @0.012% (14.43%).
