A decade ago, 【23】______ the infrared(红外线的)scanning technology developed for military purpose and other satellites, physicist Stephen Paley 【24】______ a quick way to take the temperature of crops to determine 【25】______ ones are under stress.

The data were 【31】______ into a color-coded map showing 【32】______ plants were running "fevers". Farmers could then spot spray, using 50 to 70 percent less pesticide than they 【33】______ would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers 【34】______ the new technology and long-term backers were hard 【35】______ .

"This technique can be used 【37】______ 75 percent of agricultural land in the United States," says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Depart ment of Agriculture, thinks 【38】______ infrared crop scanning could be adopted by the end of the decade. But 【39】______ Paley finds the financial backing 【40】______ he failed to obtain 10 years ago.
