“They do not act as quickly as pesticides, so cannot be used as a rescue treatment. Natural enemies are best used preventatively, early in the cropping cycle, when plants are small, pest numbers are low and pest damage has not yet occurred,” she added.
Biological controls also reduce worker exposure to pesticide and pesticide residues, limits spray damage, requires limited equipment for application and improves plant quality. Integrating biological controls also lengthens the lifespan of effective pesticides used in greenhouses by reducing opportunity for the development of resistance. [Read more…]
