Impatiens necrotic spot virus (INSV) is a pathogen that has emerged as one of the lettuce industry’s top concerns on the Central Coast of California. It's estimated that in 2020 growers suffered as much as $100 million in losses due to INSV.
Thrips are roughly half the size of a grain of rice so it’s hard to believe that an insect this small could do millions of dollars of damage to crops in the Salinas Valley each year.
