Azadirachtin (Aza) is a key ingredient of neem-based pesticides. However, use of neem pesticides is limited due to storage instability of Aza. In this work, freeflowing fine powder of whole dry neem fruits (powder neem formulation, PNF) is developed without separately extracting Aza. The optimal particle size was found to be −44 + 60 mesh. PNF is characterized by Fourier transform infrared, X-ray diffraction, Brunauer- Emmett-Teller surface area, particle-size distribution and scanning electron microscope. Stability of Aza was found to be improved and it was assessed by studying the effect of particle size, temperature, UV light exposure and release study in buffered and natural water samples.Keywords

Neem-based pesticides are well known to reduce agriculture pollution. It was earlier found that free flowing fine powder of whole dry neem fruits (called PNF-powder neem formulation) of size range 300 μm to 390 μm, i.e. (−44 + 60 mesh) was the optimumsize range. Azadirachtin which is a key ingredient of neem is quite stable in PNF. This article delineates material and energy balance to produce 1 tonne of PNF on a commercial level by using hammer mill. The particle size distribution models and classical energy consumption models were used to fit the experimental data generated by changing the hammer millscreen.Keywords
