Abstract
In recent years, the use of single-node seedlings for sugarcane
cultivation has gained prominence due to its potential to reduce planting costs
and enhance seed cane quality. Raising seedlings in portrays or polybags under
shade net conditions offers distinct advantages for seed production. However,
under these transplanted conditions, the early shoot borer (Chilo
infuscatellus) has emerged as a major pest, especially under
post-transplant stress. Infestation during this vulnerable stage often leads to
complete seedling mortality, severely affecting plant stand establishment and
ultimately reducing cane yield. To address this issue, a field experiment was
conducted over three consecutive seasons (2016–2019) at the Regional
Agricultural Research Station, Anakapalle, Andhra Pradesh, India, to evaluate
the efficacy of selective insecticidal treatments against early shoot borer in
transplanted sugarcane. The most effective management strategy involved sett treatment
with imidacloprid 600 FS @ 1 ml/L, combined with soil application of
chlorantraniliprole 0.4G @ 22.5 kg/ha at transplanting and again at 60 days
after transplanting (DAT). This integrated approach significantly reduced early
shoot borer incidence to 6.57% dead heart (DH), representing a 78.44% reduction
compared to the untreated control (30.47% DH). It also resulted in the highest
number of millable canes (81,600/ha) and cane yield (102.82 t/ha), translating
to a 33.15% yield increase over the control (64,680 canes/ha; 77.22 t/ha). The
next most effective treatments were sett treatment with imidacloprid 600 FS @ 1
ml/L plus soil application of fipronil 0.3G @ 25 kg/ha at transplanting and 60
DAT, and foliar application of chlorantraniliprole @ 0.3 ml/L before
transplanting and again at 60 DAT. These treatments achieved yield increases of
28.58% and 26.39% over the control, respectively, and were statistically at
par.
