Crop protection is the practice of managing pests, weeds and diseases that affect agricultural crops. It is generally achieved by the implementation of pesticide-based approaches, barrier-based approaches, biological pest control methods, animal-psychology based approaches and methods of biotechnology. Ploughing and cultivating the soil prior to sowing potentially reduces the risk of pests. Pesticide-based approaches include the use of herbicides, insecticides and fungicides. Biological pest control is a method of pest management that encourages herbivory, predation, parasitism, or other natural mechanisms. Diseases in crops are generally prevented by using pathogen-free seeds, controlling field moisture, or implementing approaches like crop rotation. This book provides comprehensive insights into the latest advances in agricultural science. Most of the topics introduced herein cover new techniques of crop protection. For someone with an interest and eye for detail, this book covers the most significant topics in this domain.
