Study of Physiochemical and Properties of CNSL based Termiticides
Abstract
Cashew nutshell liquid based termiticides using neem seed oil, karanj seed oil and bhilawan shell liquid, were developed and the effect of formulations on acid value, Iodine value, saponification value and unsaponifiable matter of CNSL termiticides was studied. It was observed that CNSL based termiticides were oil based therefore the acid value, Iodine value, saponification value, unsaponifiable matter, flash point, fire point, refractive index, specific gravity, viscosity and colour properties of CNSL, Neem seed oil, Karanj seed oil and Bhilawan shell liquid were reflected in the termiticide formulations with respect to the temperature.

Introduction
Termites are now a day becoming nuisance to urban as well as rural areas causing loss of crores of rupee world over. Hazardous and costly chemicals are being used to control the termites which are leading to dreadful diseases. Therefore, Termiticides are applied to wood furniture and other articles made of wood by brush and by dipping in solutions. Termiticide solutions are absorbed in upper layer of wood articles but may be affected by temperature and humidity. The influence of atmospheric temperature on physicochemical properties of oils may affect the mixing of oils, forming uniform coat on the surface of wood samples and absorption of solution by wood samples when dipped in it. Chemical properties of these termiticides may be responsible for the retaining of termiticide inside the wood articles and become resistant to termites. the study on ‘Development of Cashew NutShell Liquid based Termiticide’ was undertaken in the Department of Agricultural Process Engineering, College of Agricultural Engineering and Technology, Dr. BSKKV, Dapoli with the objective to study the effect of temperature on some physicochemical properties of Cashew NutShell Liquid, Neem seed oil, Karanj oil and Bhilawan Shell Liquid.
Conclusion
To search the alternatives to the chemical termiticides, CNSL based termiticides were developed by using NSO, KSO and BSL indifferent proportions. Physicochemical properties of sixteen formulations were determined. Effect of temperature on some properties as well as effect of proportions of oils on physicochemical properties of sixteen formulations of termiticide was studied. From the results obtained it is concluded that physicochemical properties of CNSL, NSO, KSO and BSL can be reflected in the CNSL based termiticides developed.
