Abstract: Chemical control techniques, such as using pesticides and combinations with high effect and low toxicity, and ecological strategies, were applied to decrease costs and increase effects in rice pest management. Compared to the conventional\|managed fields, the pest control efficiency in the treated area was increased by 0.02%~6.88%, chemical consumption was reduced by 2.01 kg·hm-2(83.31%), rice grain yield was increased by 1.36 t·hm-2, and the income was increased by 4 665.75 yuan·hm-2. The results above suggested the high potential of chemical control techniques in the sustainable intensive rice production system.
