Abstract

                                is common knowledge that insects and several other mem-- bers of the animal kingdom cause ravages on our crops. Drought, floods, extremes of temperature, heavy winds, excessive rain, improper drainage, toxins in the soil and a variety of unexplained for partially explained causes are also known to take their toll of crop plants. Besides the above, crop plants are subject to several diseases caused by parasitic fungi. Fungi are members of the vegetable kingdom representing a low order of creation, and are ordinarily too small to be visible to the naked eye but they could be made visible with the aid of a microscope.
