<i>Bt</i> cotton pest resistance study wins Chinese award
A Chinese research project on cotton bollworm ( Helicoverpa armigera) resistance to genetically modified insect-resistant Btcotton has been awarded a second class national Chinese science and technology progress prize, reports the Chinese newspaper, Farmer’s Daily. The project was headed by Dr Kongming Wu, director of the Plant Protection Research Institute of the Chinese Academy of Agricultural Sciences. Among other findings, the study suggests that the implementation of small-scale farming of non-cotton host plants such as maize, wheat, soybeans, and peanuts, can provide an anti-resistance refuge strategy. The Ministry of Agriculture is making use of the findings in its biosafety assessment, management and monitoring of commercialised Bt cotton. China's planted area of Bt cotton fell by 5.4% to 3.5 million ha in 2010 ( Agrow No 611, p 22).
