Colusa

I have received reports of significant defoliation due to armyworms from several areas: Glenn, Colusa, Butte and Yolo counties. In most areas the defoliation is severe but the area affected within fields still small. I inspected a field in Glenn County.

Moth numbers have increased since the week of June 12, specially in the Colusa trap. The degree day model predicted worms in the fifth instar by June 22; I'm starting to receive reports of worms in Colusa, Glenn and Butte counties.

The number of moths trapped has increased in all locations, except in the North Sutter one (which was already high to begin with). In most fields the rice is still in the three to five leaf stage.

Grow Rice? Help Birds! Rice provides livelihoods and food for people and places to rest and feed for many birds, too. Small changes to field management can increase the value of rice fields for the birds that use it.

The University of California Cooperative Extension annual rice meetings will be held this week. As usual, we will have four locations. However, note the change of venue for the Glenn and Colusa meetings this year.

In the past year, the California rice industry has begun to deal with a new pest: weedy rice, also known as red rice. Weedy rice is a common weed in rice-growing regions of the world, and when infestations are high, it can significantly reduce yields.

Please see this article on the UC Rice Blog for an update on armyworm populations. We will continue to monitor traps in the Delta through mid-September, and we will plan to monitor populations next season.
