Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
cyantraniliprole 10.26 OD @ 900 ml/ha, soil drenching with clothianidin 50 WDG & one foliar
spray of spinetoram11.70 SC and soil drenching with clothianidin 50 WDG & one foliar spray
of cyantraniliprole 10.26 OD which recorded seed yield in the range of 9.82 to 11.56 q/ha.
Conclusion
The overall results on bio efficacy of insecticides revealed that the treatments with two foliar
sprays of spinetoram 11.70 SC @ 420 ml/ha and the treatment with two foliar sprays of
cyantraniliprole 10.26 OD @ 900 ml/ha were found most effective for the control of safflower
aphid and in obtaining higher seed yield.

Globally, rice (Oryza sativa L.) is one of the most important food grains. In India, out of 44 m
ha of total rice producing area about 45 per cent is irrigated, 33 per cent is rainfed lowland, 15
per cent is rainfed upland and 7 per cent is flood prone. As major portion (55 per cent) of rice
producing area is rainfed, crop often suffers from a variety of stresses. In recent past, the area
under rice has decreased due to increased cost on transplanting and weeding operations. At the
same time, delay in transplanting due to labour shortage and non-availability of irrigation
water at the peak period causes yield reduction and less profit (Gangwaret al., 2008). Hence,
the major challenge is to mitigate the adverse effects of changing climate so that growth in
rice production can be sustained and food security can be achieved. To increase the
productivity of stress-prone ecosystems, a combination of improved varieties and crop
management options that are more tolerant to volatile climate under stress-prone environment
is necessary to ensure food security and at the same time provide viable incomes for resource
poor rice farmers (Haefeleet al., 2010, Singh et al., 2014). As all stress tolerant rice varieties
