There are two main types of genetically modified crops. One type is resistant to pests. The other type is resistant to weedkillers. In the case of rice, the main trials have been of rice that is resistant to pests. In one trial of this rice, which was reported in the journal Science, the farmers growing the GM rice used less pesticides than the farmers growing unmodified rice. The scientific report is here, but you may find it hard to understand. There is a simpler version based on a press release here. I am sorry but I cannot tell you which web sites are more reliable. Thanks for your question. Jeremy
