AgroZ bag and AgroZ bag plus


AgroZ bags and AgroZ bags plus are double layer bags consist of a gas-proof inner bag placed inside a much tougher open weave polypropylene (PP) bag for protection against physical damage. After filling they are tied shut with string. The bags are gas-tight (hermetic) so that some weeks after being filled with grain and tightly closed, a modified atmosphere is created that will kill insect pests. 



Pest Control Status: Pest control is native
Storage Period: 3-24 months
Capacity: 50kg - 100kg
Lifespan: 1 year - 2 year
Initial cost: US$ 27 - 70
Cost per tonne per year: US$ 13.5 - 35

Commodities stored:

Tanzania and Kenya  - Cereals, pulses and dried cassava






Materials used:

A mixture of HDPE and other polymers.  In the case of AgroZ Bag Plus, a special LGB repellent layer is incorporated within the multilayer construction.  This is sandwiched between two impermeable layers to prevent migration of an insecticide (alphacypermethrin) to either the stored grain or to the outside of the bag.


Locations made:

Arusha, Tanzania, by A To Z Textile Mills Limited





Life span:

Expected lifespan is to be 3 years but this has still to be confirmed






Marketing and promotions:

The AgroZ Bag has been already been launched in nine counties of the Rift Valley, Kenya, during November 2015 and is also available for sale in Tanzania. AgroZ Bag Plus is already registered in Tanzania and is currently undergoing registration trials in Kenya.



Success and nature of marketing:

No information



Training as part of the campaign:

No information






Degree of adoption:

Hermetic bags are not widely used in East Africa. Awareness will have to be raised and demand created. This is likely to be a lengthy and expensive process requiring donor support.



Reason for adoption:
  1. Control (by asphyxiation and dehydration) of all storage pests including LGB.
  2. Manufacturers suggest resistance to LGB penetration of hermetic bag from either the inside or outside.
  3. No requirement to use insecticide treatment directly on the grain, thus eliminating health risks and other MRL related issues such as rejection by importers.
  4. Reduction in aflatoxin risks.
  5. Very affordable cost compared with metal or plastic silos and metal drums.


Weaknesses of this store:

AgroZ bags are not yet widely used.  No 'weakeness' have been listed. For a more balanced view read comments in the 'Uptake' section for other double layer hermetic bags, e.g. GrainPro SuperGrainbags



Barriers to adoption:
  1. Hermetic bag storage technology is at a very early stage of introduction in East Africa. Lack of awareness of the technology and its benefits to small holder farmers will have to be addressed through extensive demonstrations and training.
  2. Lack of credit facilities as farmers’ needs to raise cash at harvest time (when grain prices are low) together with expected post-harvest losses which is a disincentive to storing grain on-farm.
