What are the best methods of stored grain management?
In the 1990s, Purdue University scientists developed the SLAM approach of integrated pest management (IPM) practices. SLAM stands for Sanitation, Loading, Aeration, and Monitoring. Good sanitation to minimize grain insects includes sealing of structures to eliminate insect entry through base and sidewall openings. Storage roofs need to be partially open (roof vents) to allow some air movement, but screening vents to eliminate insects is a sanitation measure which would help maintain grain quality without chemicals. Aeration to cool grain and keep grain temperatures uniform to eliminate moisture migration and mold is a major non-chemical tool of excellent grain management. Grain stored without residual chemicals protectants — is preferred. Combining aeration with fumigants like phosphine(PH3) or sulfuryl fluoride (SF), gases which leave no residual on the grain, is an excellent grain management process. Use of diatomaceous earth (DE) as empty bin treatments which provide long-term, non
