Green Prevention and Control Technologies for Common Tomato Main Diseases and Pests

Tomato (S. lycopersicum L.), an important and popular vegetable among people, is grown in fields and greenhouses in almost all countries in the world. With the continuous improvement of living standards, the people’s demand for fresh fruits and vegetables is also increasing day by day. Nevertheless, tomato production worldwide remains highly vulnerable to both abiotic and biotic stresses. In particular, infection, feeding, and competitive growth of some pathogenic microorganisms, pests, and weeds have significantly reduced tomato production, severely limiting development of the tomato industry and impacting the supply–demand balance. Over 200 species of tomato pathogens have been identified as causing production problems. Approximately 100 insect pests and 25 non-insect pests attack tomatoes. The heavy use of chemical pesticides has led to plant resistance to diseases and pests, leftover pesticide residues, and environmental damage, all of which pose risks to food safety and human health. Therefore, strategies to reduce pesticide use and the implementation of environmentally friendly control measures for plant diseases and pests must be explored. In this chapter, we review the major tomato diseases and pests and their prevention and control measures, thereby providing theoretical support for the green and sustainable development of the tomato industry.
