In this complex world of new technology, growers can be lured into forgetting some of the most basic checks and controls to prevent outbreaks of disease. These 10 basic principles are described in "FlowerTech" by Dr. Steve Nameth. 1. Always start with disease free seed or propagation material; 2. Grow disease resistant varieties; 3. Quarantine all incoming plant material; 4. Practise good sanitation techniques in the greenhouse; 5. Monitor and suppress insect and mite populations; 6. Modify the environment to limit disease; 7. Avoid putting plants under stress; 8. Monitor production each day; 9. Keep unauthorised and inexperienced personnel away; 10. Use funcides sparingly, mainly as a last resort. www.hortiworld.nl
