Abstract
Sterility mosaic disease (SMD), which is transmitted by the eriophyid
mite Aceria cajani, is a major problem in cultivation of redgram (Cajanus
cajan L.) which causes yield reduction. A field study at S.V. Agricultural
College, Tirupati, Andhra Pradesh, during kharif and rabi 2025-26
evaluated four sowing dates (22 June, 7 July, 22 July, 7 August 2025) in
variety LRG-52 (Amaravati), for their effect on mite build-up, SMD incidence
and yield. Mite population and disease incidence were highest, and yield
lowest, in the earliest-sown crop; the 22 July sowing recorded the lowest mite
population and disease incidence and the highest yield (1,850 kg ha⁻¹). Results
establish a clear inverse relationship between vector/disease pressure and
yield, and identify late-July sowing as an effective cultural tactic to reduce
SMD losses.
