Education and climate are suitable for the fungus Fusarium in corn study environment. Temperature and humidity are suitable for the fungus Fusarium are contaminated and result in harm to consumers, maize and cause disease or Fusarium stalk rot disease early rot in corn. Passenger contamination is caused by fungal spores blowing in the air and on the corn. The variables studied include: Weather temperature and humidity. The introduction of corn each to the place designated period 7-day trial with the experimental fourth place is set at one location in a damp, set the second set in the outdoor unit 3 is set forth in the narthex. the fourth series is set in the refrigerator. The results showed that the first set in the humid temperature and relative humidity averaging 66% average 31◦c set the second set in the average outdoor temperature and relative humidity of 31 ◦c average 61% of the third set. set the opacity in the average temperature and average relative humidity 61% 30◦c set at four locations in the refrigerator thermometer 12◦c average relative humidity and average 32%.
