As the days get shorter and the temperatures begin to cool, now is the time to practice weed management for annual cool-season weeds. It's also not too early to consider management for weeds that emerge in springtime.
Using integrated pest management (IPM) methods can help reduce the presence of most weeds. In lawns, good practices such as proper watering, mowing, and fertilizing can help maintain healthy turfgrass. Likewise, in landscapes, hand-weeding, cultivation, and use of mulches can be effective in controlling weeds. More specific information about these and other IPM practices can be found in our Pest Notes publications on
Your customers want their lawns to be beautiful and functional (Figure 1) but dead patches or other problems sometimes occur. Figuring out the cause of turfgrass damage can be a challenge since many plant pathogens affect grasses as well as numerous abiotic (non-living) disorders. can impact the quality of lawns, playing fields, and other turf areas.
Keeping turfgrass healthy is essential for reducing damage due to both diseases and abiotic disorders. Following recommended practices regarding irrigation scheduling, integrated pest management, fertility, mowing height, soil aeration, and other measures is your customer's best line of defense.

Warmer weather means many pests are flying and joining you indoors while you shelter-in-place or outdoors while you are getting some exercise or keeping connected yet socially distant from the neighbors.
Lately you may have seen some large, leggy insects bumbling around on your walls and windows. What are these? While many people call them “mosquito eaters” or “mosquito hawks,” they are actually crane flies. And unfortunately, they do not eat mosquitoes. These insects may be a nuisance when you find them in your home, but the adults are basically harmless. Although the adults are not particular pests of importance, the larvae can be...
Gophers are well-known and certainly unwelcome pests in landscapes, gardens, lawns, and athletic turf. More correctly called pocket gophers, these rodents mostly remain hidden underground in tunnels and feed on plants from below, sometimes pulling whole plants into their tunnels. They prefer herbaceous plants but will eat a wide range of vegetation.
A single gopher can destroy a landscape quickly, so control measures need to begin as soon as the gopher is detected. Mounds of fresh soil are usually the first indication of their presence. Effective integrated management of pocket gophers relies largely on exclusion measures and trapping, although poison baits are also available.

Have you seen big green beetles in your California yard or garden? Or beetles feeding on your roses or other plants? There are many kinds of beetles commonly found in our landscapes, but the Japanese beetle is not one of them.
Many people think they've seen the Japanese beetle, a small scarab beetle with metallic green wings with white spots on the margins. However, Japanese beetles are generally not found in California.
The Japanese beetle is an exotic and potentially invasive pest for which the California Department of Food and Agriculture (CDFA) is conducting eradication efforts to limit its spread.../h2>
