along with insect pests like BPH and WBPH, or stem borer in heading phase of the crop, in those
circumstances, the fungicides like edifenphos or IBP, which have some insecticidal properties, have to be
used. In these circumstances, these are going to have adverse effect on natural enemies of insect pests.
This type of information need to be generated and made available to the farmers for their guidance and
corrective measures.
COMBINING INSECTICIDE USE WITH VARIETAL RESISTANCE
Donors and varieties with high level of resistance are available only for gall midge followed by moderate
to good level of resistance for BPH, WBPH and GLH. Very few varieties with low level of resistance are
