It is getting close to the time we need to scout for weedy rice. Our team will be scouting known infested fields that are planted to rice this year. Troy Clark, our Rice Junior Specialist, will be starting in the next few weeks, and will be reaching out to growers and PCA's. Like always, the more eyes on the ground we have, the better! So we are asking for everyone to please scout their own fields to look for suspicious plants.
For timing of scouting, the best time to start, is if you have applied all herbicides to control grasses, and you are still seeing what appear to be skips or misses in grass control. At that point, it is a good idea to go out and check the plants. If they do not have a ligule and auricle, then they...

Several months ago, I got a question about weeds in an irrigated pasture. The mystery plants were slowly but surely taking over a significant proportion of the pasture, and the owner asked me to visit the property to identify the plants and options to control them.
A brief detour in my story, for important context: Before I visit any property, I map it so I know how to get to their entrance road – which is often a dirt road that doesn't show up correctly on the standard view in Google Maps. To make sure I know what I'm looking for, I switch to satellite view to find the necessary roads.
Because I'm typically looking for roads and not looking at landscapes, I got a pleasant surprise when mapping this property. I...

The UC Statewide Integrated Pest Management Program's website contains many useful features to help identify pests and problems in the garden and home. One such feature is the Weed Gallery, which contains hundreds of images and management tips for more than 150 common weeds found in California.
If you don't know what weed you are dealing with, the gallery will help you identify the plant using visual characteristics. First, narrow your search by selecting the weed category—broadleaf, grass, sedge, or aquatic plant (Figure 1). You will then see a collection of photos in that...

From the Cornell Chronicle--June 22, 2022
Farmers can tailor their efforts to control weeds more effectively by pinpointing when a particular weed will emerge, according to a new Cornell study.
Researchers in the College of Agriculture and Life Sciences reviewed past studies on the peak timing of emergence for 15 troublesome weed species in the Northeast, as well as potential ways to use this knowledge, in their study,
