From June 2008 to August 2010, a total of 175 samples of edible fungus Flammulina velutipes, shiitake mushrooms and Pleurotus ostreatus collected from central and southern areas of Gansu Province and pesticides for irrigation water and culture material (cotton seed hulls) from three edible mushroom production bases Residues were investigated. The results showed that DDT, methamidophos and other highly toxic and highly toxic pesticides, thiophanate-methyl were not detected in 175 samples of three kinds of main edible mushrooms; a small amount of carbendazim, cypermethrin and deltamethrin residues , But all were within the detection limit. No pesticide residues were detected in the irrigation water of the three production bases. Carbendazim, cypermethrin and thiophanate-methyl were detected in the culture materials (cotton seed hulls) of the three production bases, of which, Longnan Town Kangxian edible fungus demonstration base production base material (cotton seed hull) samples also contain DDT 0.0635 mg.kg-1, deltamethrin 0.010 mg.kg-1, are within the detection limit.
