I am performing Plant disease detection.so I want to identify the mostly green colored pixels. After that, based on specified threshold value that is computed for these pixels, the mostly green pixels i want to masked as follows: if the green component of the pixel intensity is less than the pre-computed threshold value, the red, green and blue components of the this pixel is assigned to a value of zero. pleae give me solution for Masking the green pixels

It seems that you have a good idea on what has to be done. What have you tried so far?

See my "color detection by hue" tutorial in my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 It can do this. Simply adapt the thresholds, by looking at the histograms, to select green instead of yellow.

At the risk of being accused of shameless self-promotion... I blogged about a similar problem on Steve Eddins's Image Processing blog. Perhaps some of my experiences might be of use?
