Abstract

Our world is facing tremendous crop losses. Crop losses occur due to pathogens which may be fungi, bacteria, nematodes, viruses, etc. It has been observed that the major crops particularly wheat, rice, maize, and potato which are consumed in most of the countries are being affected by the pathogens and causing financial breakout throughout the decade. To minimize the crop losses farmers are consuming chemical pesticides on a large scale. Chemical pesticides control diseases to some extent but its effect is quite dangerous. Chemical pesticides cause great loss to the environment, it kills the beneficial microbes which are present in the topmost soil. It also causes diseases such as cancer, skin diseases to human beings. Thus to minimize the consumption of chemical pesticides, more emphasis should be given to herbal pesticides. Herbal pesticides not only protect the crop from being infected, but it also causes no harm to human being. It is eco-friendly, cheaper, and can be easily produced.
