Pre- and Post-harvest Preventive Measures and Intervention Strategies to Control Microbial Food Safety Hazards of Fresh Leafy Vegetables
Spinach is a generic term for certain vegetables which are grown, cooked and consumed for the high content of minerals and vitamins in their leaves. The term spinach may refer to plants from five different families, including English or common spinach (Spinacia oleracea), silverbeet or Swiss chard (Beta vulgaris), French spinach or orach (Atriplex hortensis), New Zealand spinach (Tetragonia expansa), Chinese spinach (Amaranthus gangeticus), water spinach (Ipomoea aquatica) and Indianspinach (Basella rubra).
This publication is an extensive vegetable production guide that addresses topics such as marketing aspects for production decisions, general production considerations, insect management, weed management, and disease management. You will find specific information for the following crops:
The spinach production manual addresses the following topics:
- Seeding and planting
- Fertilizer and lime
- Plant tissue analysis
- Weed management
- Insect management
- Disease management
The Guide is divided into three sections. The first section provides cultural information and management practices for a number of important vegetable crop groups. For each family, key pests and disease problems are described. Cultural methods and management practices that will help control each problem are listed, as well as materials that may be recommended for use.
Vegetable seeds can be saved to sow new crops in the future, but not all seeds are suitable for saving. Varieties suitable for seed saving include local varieties that have been grown in one region for a very long time, self-pollinating crops (for example, beans and peas), and open-pollinated varieties of some cross-pollinating crops (for example, pepper, cucumber and carrot).
Variable agronomic practices, cultivar, strain source and initial contamination dose differentially affect survival of Escherichia coli on spinach
Aims: Greenhouse and field trials were conducted under different agronomic practices and inoculum doses of environmental Escherichia coli and attenuated E. coli O157:H7, to comparatively determine whether these factors influence their survival on leaves and within the rhizosphere.
