Want Your Crops To Survive Extreme Heat and Drought? Add Fungus  The global population continues to grow and climate change is already tangibly reducing food harvests. Can agriculture adapt to be both more productive and more resilient?One answer to that question may be add  fungus. Issie Lapowsky reports today for WIRED  that a Seattle-based startup named Adaptive Symbiotic Technologies is almost ready to put a fungi-based product on the market that enables rice corn and other crops to bear up amazingly well during  drought and temperature extremes.According to Lapowsky the product called BioEnsure is a blend of microscopic fungi that Dr. Rusty Rodriguez and his wife Dr. Regina Redman first discovered in the 1990s. They had been trying  to figure out how some plants were able to grow in the barren soil and peak 150 degree-Fahrenheit  temperatures at the center of Yellowstone National Park.  They discovered that fungi had colonized the plants and essentially lent them extra resilience. When the fungi were removed in the lab the plants failed under the same heat.Since 2008  Redman has been tweaking fungi blends to work with  wheat soybeans rice and corn crops.BioEnsure has been proven in real-world conditions  Lapowsky writes:During the drought that destroyed much of the cropland in the Midwest in 2012 for instance BioEnsure-treated corn crops generated 85 percent more yield than plants that were not treated. And in temperate climates BioEnsure has been proven to increase output by 3 to 20 percent. What s more says [AST vice president of business development  Zachery] Grey BioEnsure appears to be particularly effective on organic crops which aren t treated with chemicals and other additives for protection.AST has been nominated (along with 16 other contestants) for a  Securing Water for Food  award by the U.S. Agency for International Development. The young company's  next big hurdle may not be extreme weather reports Lapowsky but the influence of the agriculture-industrial complex that reaps massive profits from chemicals that BioEnsure could render unnecessary.
