SEALING AND PRESSURE TESTING GRAIN STORAGE FOR OPTIMAL PEST RESISTANCE

With more grain being stored on-farm than ever before, it’s critical that grain storage equipment is up to the task when it comes to protecting stores from pests; and in particular those which may develop resistant to pesticides.

Using your pesticides as per the instructions on the label is a good start to extending the life of a pesticide in your stores, however there is much more you can do to ensure the high quality of your grain is maintained during storage.

Sealing your silos:

A sealed silo with easy access to a pressure relief valve is a must-have. We have developed the ‘Optimum Seal’ to ensure that the required concentration of pesticide is present for the duration of storage, reducing the risk of sub-lethal doses and the development of resistant pest populations in your stored grain.

Pest contaminated grain has the potential for an entire silo load to be damaged and downgraded; so the importance of investing in a sealed storage system is clear. A sealed silo will also allow for an even and accurate dosage of pesticide to occur; meaning you get consistency in quality throughout your stores.
