Spinosad – Monterey

Spinosad works on the insect’s nervous system, causing paralysis and then death in 1-2 days. Since the insects are paralyzed, they may stay on the plants and be mistaken for live insects; always check for Spinosad’s effect 2-3 days after spraying to evaluate control in the insect population. From here.

Began using it in June 2020.

Mix – 4 Tbsp or 2 oz. per gallon. The addition of a surfactant is good for leaf miners.
