The old saying, “Everything's fine until it's not,” comes to mind when dealing with some tough to control perennial weeds in alfalfa production during the summertime. Such was the case for an alfalfa field in the Sacramento Valley, where weed control seemed good up until mid-summer, and then it wasn't. Perennial weeds that started off small and overlooked, grew through the season, persisting through multiple cuttings, including curly dock, plantain, and nutsedge. For tough to control weeds in alfalfa fields, one needs to determine: 1) What types of perennial weeds are present, and 2) How many of them are there, to make a decision on how to manage them. These sorts of weed issues can creep up quickly in older alfalfa...

Help the environment this Earth Day, which falls on Sunday April 22 this year, by installing insectary plants! These plants attract natural enemies such as lady beetles, lacewings, and parasitic wasps. Natural enemies provide biological pest control and can reduce the need for insecticides. Visit the new UC IPM Insectary Plants webpage to learn how to use these plants to your advantage.
The buzz about insectary plants
Biological control, or the use of natural enemies to reduce pests, is an important component of integrated pest management. Fields and orchards may miss out on this control if they do not offer sufficient...

Spiny buttercup (Ranunculus muricatus) is a non-native plant, that is fairly common, especially in wet areas such as meadows. We also find it in crops, including orchards, pastures, and cereal grain fields. It's both an annual and perennial plant that blooms from March to May, with seed pods that are large and prickly. Though it's pretty with the bright yellow flowers, don't be fooled, as it has a dark side, so should be controlled.
First, according to Dr. Birgit Puschner, UC Davis Vet Med Toxicologist, all buttercups contain ranunculin, though there are differences in species in terms of toxin levels. In pastures, because the plant is bitter, animals simply eat around it. But if ingesting the fresh plant, they...
