Reducing insect damage means: • more maize to eat and sell• more nutritious maize so your animals
gain more weight• improves food security

I won’t recommend just one way to store grain, but I will discuss good, better, and
best storage methods

Maize Weevil
• One weevil produces about 300 weevils in only 2 months!
• Adult Weevil
Weevil Pupa

Infested grain results in:
• Less grain weight – You can easily lose half of your grain to insects!

Infested grain results in:
• Less grain weight.• Less nutrition – It is less healthy for you!
![Page 13: Storing Grain to Reduce Insect Damage (Floyd Dowell, Planting Hope International)](https://reader031.fdocuments.net/reader031/viewer/2022032805/568133d2550346895d9acaaf/html5/thumbnails/13.jpg)
Infested grain results in:

make a good crop next year!

Tips For Preventing Insect Damage
• Clean the area before storing to remove existing insects.• Treat the area before storing with a pesticide.• Mix chemical dust with the grain.

![Page 21: Storing Grain to Reduce Insect Damage (Floyd Dowell, Planting Hope International)](https://reader031.fdocuments.net/reader031/viewer/2022032805/568133d2550346895d9acaaf/html5/thumbnails/21.jpg)
Types of Pesticides• Chemical dusts (Actellic Super, Actellic Golden
Dust, Shumba Super, Stocal Super, Spinosad)• Chemical gas (Phostoxin, Methyl Bromide)• Diatomacious earths (Protect-It, PyriSec, and
DEA-P, Dryacide )
Always follow manufacturer instructions.
Never purchase products that have been opened! You might be buying flour!

Oxygen free bags can be used to control insects without pesticides.
BUT, must be protected against rats.
Rats!

Tips For Preventing Insect Damage
• My recommendation:– Get several clean barrels.– Fill with clean, dry grain mixed with Shumba or
Actellic, preferably in a oxygen-free bag.– Treat with photoxin.– Seal the barrel as tightly as possible.– Store in a cool, dry place.– Check monthly and treat as needed.– If you do this, you should have NO insect damage!
