Biocontrol Systems and Plant Physiology in Modern Agriculture: Processes, Strategies, Innovations focuses on new production alternatives that do not include pesticides, herbicides, and chemicals for primary food production and instead rely on biologically controlled systems of production. The book also relates a number of advances and innovations in the use of agricultural technologies that employ the study of the physiology of plants to know their resistance to different environments in modern agriculture. The book presents research offering viable alternatives for the control of pests for safe food production that are environmentally friendly and that facilitate the reduction of production costs and improve the quality and yield of produce. The volume addresses innovative biocontrol systems to reduce or eliminate the use of agrochemicals by controlling plant diseases by minimizing environmental damage through the use of antagonistic organisms. It also presents new strategies of cultivation that maximize production by optimizing light, temperature, humidity, nutrients and humidity in a controlled environment. The diverse topics in the volume include botanical compounds as adjuvants as an alternative to reduce the pesticide use, on-site production of bio-control agents, plant factory systems that offer controlled safe environments for plant cultivation, promising bio-nematicides for sustainable agriculture, wastewater reclamation for agricultural purposes, the recovery of phytochemicals from plants, using LED lights on plants and microgreens production, and much more. Covering the new trends in biological control, plant factories, and plant metabolism for application in modern agriculture, this volume provides important research and knowledge that facilitates environmentally friendly plant systems, advances the reduction of production costs, and improves the quality and yield of produce.
