forbid-used用法不对，其它是可以的。另外thus providing scientific basis for choosing, demonstrating and spreading the alternatives of high-toxic pesticides and the relevant techniques on a large scale.这里面其实可以把of high-toxic pesticides去掉，因为从上下文都能知道这里的alternative是什么意思

Therefore nationwide tests on substitute species for methamidophos have been conducted to evaluate the effects of control for rice planthopper, and study relevant techniques, then provide scientific basis on selecting substitute species and relevant techniques of demonstration and extensive application in a large area.

Rice planthopper, an important rice insect in China, is often controlled by application of high-toxic pesticides such as methamidophos. Since Jan. 1st, 2007, five high-toxic pesticides including methamidophos have been forbidden for use in China. Therefore nationwide experiments on alternatives of methamidophos have been conducted to evaluate their efficacies on controlling of rice planthopper and study the relevant application techniques, so as to provide scientific basis for choosing, demonstrating and applying the alternatives of high-toxic pesticides on a large scale.
