What is meant by 'indirect plant protection?"
Indirect plant protection is the use of methods that prevent the outbreak of disease and insect damage beyond an economic threshold. This is an attempt to establish and manage the vineyard in a way to prevent problems that would later need to be addressed by higher off-farm inputs. One example of a preventable problem would be the planting of late-ripening varieties prone to rot that would later need several Botrytis sprays to combat this disease. A second example of a problem that could be prevented would be the installation of a training system that caused too much shading and increased the incidents of disease requiring additional sprays.
