Overview
Snow peas require the use of pesticides to control leafminer, which can cause cosmetic damage to the product and reduce its marketability. The tolerance level for leafminer damage to the snow pea pod for export is practically zero. The use of beneficial organisms as biological controls could help reduce the levels of leafminer fly populations and pod damage, and also contribute to reduction in insecticides use. The ICTA
Objectives
The objectives were to establish whether the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana would reduce leafminer fly adult populations and in turn reduce the damage caused by the larval mining on leaves or the snow pea pods.
Outcomes
No differences were found among the percentage of damaged pods between any of the treatments, which ranged between 4% and 7%
