Treatment of Stored Grains
Grains and pulses can be stored by mixing them with neem products like dried leaf powder or oil. The Neem oil used against stored grain pests should be 1 percent by weight of the grain. If the grain is used for seeds purpose 2 percent can be used. Using oil is easier than leaves. The active ingredients of the neem plant are located in their maximum amounts in the seed and kernel. Comparatively the active ingredients like Azadirachtin, Salanin, Malandriol are concentrated in the seed. Therefore it is always recommend to use neem seed, neem oil or neem kernel extract.

Treatment of Gunny Bags for Storing Grains
Prepare a 10% neem kernel solution. Here there is no need to add any emulsifier. Once the solution is made dip the gunny bag into this solution for 15 minutes. Dry the gunny bags in shade and this can be used for storing grains. The stored grain pests will be repelled by the action of neem. In stored grain pests will be repelled by the action of neem. In case the gunny bags are new they should be soaked for half an hour. For gunny bags with close meshes and small pores, thinner solution can be used. Make sure that the gunny bags are impregnated on all sides with this extract. If the seeds or grains are kept inside the house or in the godowns, there is no fluctuation in temperature and not much sunlight. As a result of this, longer residual action of neem product is obtained and the repellant effect persists for 4 months. In store rooms, along with cow dung that is used for cleaning the mud floor, neem cake or neem oil can be used straightway (in the same concentration as used for spraying purposes). The same could also be used for the mud walls. Neem cake solution or neem kernel extract could also be sprayed. If one is using bamboo bins for storage, then one can paint the bamboo bins with the solution prepared from neem cake. To the dry neem cake powder water is added and a thick paste of this painted all over the grain bin. If one wishes to store it for more than 4 months, the process should be repeated every 4 months.
