What measures must be taken to prevent spoilage and insect attack of harvest grain?

To prevent spoilage and insect attack of harvested grain, it is crucial to ensure proper drying to achieve optimal moisture content, typically below 14%. Additionally, storing grains in clean, sealed containers or silos with appropriate ventilation can deter pests and moisture accumulation. Regular inspection and monitoring for signs of insect activity or spoilage should also be conducted, along with employing pest control measures like fumigation or the use of natural repellents. Finally, maintaining a clean storage environment helps minimize the risk of contamination and infestation.
