Grain storage: WEEVIL INFESTATION AND FUMIGATION

Fumigation is a very common technique when it comes to treatment against weevils. However, Fumigation only works properly if adequate concentration can be maintained for an adequate exposure period. These conditions can only be achieved in a well-sealed system for a single application of fumigant or by “continuous fumigant addition” in an adequately sealed system. Good fumigation used with good hygiene and adequate sealing should not need repeating as the recommended application procedures are designed to give a total kill of all insects. Where a reinfestation appears after fumigation, it is most probable that either the fumigation was not carried out adequately or reinfestation pressures are high. Follow our discussion with Dr. Claus M. Braunbeck from FrigorTec to learn more about fumigation and how to apply efficiency. So, is there another solution to protect stored grains from weevils? Prevention is the best strategy to avoid insect problems in stored grains. During the operation of the storage site, regular cleaning is the prime activity in order to prevent weevils to find their place. Thereby not only the storage but again the whole site must be kept under control. Any spill of grain and neglected corners will be an entrance for the insects. It is also important to clean and sanitize the storage after discharge and before the next lot is loaded. Also by understanding the nature of weevils we can use #graincooling technology to maintain safe storage in a long term without regular fumigation application as well as keep the product in good quantity and quality.
