Chinese Ministry of Science and Technology has established a project to produce more food

with S&T means. The effort has rolled out numerous useful techniques to prevent and kill

major pests attacking wheat, corn, and rice in the north, northeast, lower and middle

reaches of the Yangtze River, and Chengdu Plains. Researchers have studied the mutations

of pests, their reproduction habits, and spatial and temporal distributions, based on which,

they worked out ecological regulating techniques to curb the spread of pests. For example,

they treated corn blight using fermented bacteria, cured rice sheath blight using marine

bacteria, evaluated wheat powdery mildew with mobile spore catchers, and diagnosed the

disease using near-infrared spectrum.
