When compared to the temperature that inhibited the growth of the microbes (stop disease; 35 C, for the bacteria R. solanacearum, the causative agent of wilt in tomato leaves) [7], it was found that using the hot water together with solar radiation could increase the temperature high enough to inhibit the growth of the microbes at the depth level of 30 cm, and it was better than using solar radiation alone, which inhibited the growth of the microbes at the depth level of 5 cm
