Rice is such a unique crop, and with a unique crop you’re going to get unique pests. Some California rice producers are noticing tadpole shrimp are showing signs of resistance to the pyrethroids that have managed the pest in the past. Ian Grettenberger is an assistant cooperative extension specialist with UC Ag and Natural Resources.

And so their eggs are actually in the soil. They re desiccated, dry. Once water is added and the temperature is to a certain level, then they hatch. And that corresponds with when fields are flooded with rice, and then they start growing.”

Ian Grettenberger is an assistant cooperative extension specialist with UCANR.
Grettenberger… “One, we are evaluating alternative tools because right now pyrethroids are super cheap. And so if you re going to compete with a pyrethroid you need to be competitive. And so the combination of, you know, seeing if different rates could work, lower rates could save costs or also timing in terms of, could you wait a little bit and still get efficacy, um, and thus be a little more conservative.”
