Chlorantraniliprole 0.4 GR : Novel formulation for the management of grape stem borer, Celosterna scrabrator under field conditions

Abstract

Studies were carried out to investigate the effi cacy of Ferterra 0.4 GR, a new formulation of chlorantraniliprole on the activity of grape stem borer under fi eld condition during two years 2014-15 and 2015-16. The study revealed that, the stem borer activity indicated by the amount of frass collected from the live hole was ceased successfully by soil application of chlorantraniliprole 0.4 GR (Ferterra) at the root zone. Among the various treatments, chlorantraniliprole 0.4 GR (Ferterra) @ 15 g/vine recorded lowest amount of the frass from the live holes. The frass collected was zero at 35 to 45 days after treatments during the fi rst year while during second year, the activity of the stem borer was completely ceased up to 55 days after treatment which is indicated by the zero amount of frass collected from the live holes. The standard check (dichlorvos stem injection (80 ml/l), though was effective up to 10 days of the treatments, thereafter the effi cacy of the treatment steadily decreased, and towards 55 to 60 days after treatment, it was almost on par with the untreated check. The total and average frass obtained was less in the treatment with chlorantraniliprole 0.4 GR (Ferterra) @ 15 g/vine. Further, the grape berry yield recorded was maximum in the treatment with chlorantraniliprole 0.4 GR (Ferterra) @ 15 g/vine which is on par with the higher dose of chlorantraniliprole 0.4 GR (Ferterra) i.e., 20 and 30 g/vine. The study inferred that the grape stem borer can be successfully managed with soil application of chlorantraniliprole 0.4 GR (Ferterra) @ 15 g/vine.
