*Values in bracket depict percent weight loss represented in grams. +Values in brackets depict percent weight loss and percent termite infestation. % Wt loss is mean of weight loss obtained in six wood sticks planted in soil after seasoning. It is represented in grams. % infestation represents damage caused by the termites in six wood sticks. It is also mean of number of termites available on six wood sticks.
