Host plant resistance-cum-chemical control approach for the sustainable management of yellow mite, Polyphagotarsonemus latus (Banks)

摘要

Amongst forty six chilli germplasms screened against yellow mite BCCH-SL-4 was found to be the least susceptible to yellow mite (1.5 mite/leaf) followed by SB-6-2-1 (2.8 mite/leaf). DS-1-2 (16.50 mite/leaf) and FL-1-2 (13.50 mite/leaf) were most susceptible against yellow mite. The highest yield was also obtained from BCCH-SL-4 (8.40 t/ha). Application of Dicofol 18.5 EC @ 2.5 ml/lit., spiromesifen 22.9% EC @ 1 ml/lit and diafenthiuron 1g/lit was significantly superior to other treatments.
