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.

Plantains are common weeds in lawns, athletic fields, ornamental plantings, roadsides, and pastures. Two species, broadleaf and buckhorn plantains (Plantago major and P. lanceolate) are commonly found throughout California year-round.
Plantains grow well in irrigated turf and lawns that are frequently mowed since they grow low to the ground. They can be a major pest for turfgrass managers since they grow in dense clumps, creating both an aesthetic and tripping hazard in turf. When plantains infest ornamental plantings, they can crowd out desired plants.
These weeds are difficult to control because they can resprout from the crown, even after it's cut off. Early removal of seedlings before they...
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.

Dandelions are broadleaf plants easily recognizable by their bright yellow flower and puffball of white tufted seeds heads. While this plant is appreciated as a food or herb by many, for equal numbers of others it is regarded as a weed when found growing in lawns, ornamental plantings, and athletic fields throughout the year.
For helpful nonchemical and chemical management solutions to help you control this weed, read the newly revised Pest Notes: Dandelion by UC Cooperative Extension Advisor John Roncoroni.
You may be seeing long-legged, flying insects in your house lately, bouncing around the walls, ceilings, and corners. Many people call these “mosquito hawks” or “mosquito eaters,” but unfortunately, they are not predators of mosquitoes.
These flying insects are actually adult crane flies and although annoying to find in the home, they are basically harmless and won't help with any mosquito problems.
Many reports claim these adult European crane flies (Tipula paludosa) bite or sting, but this is false. Most adult crane flies, which superficially resemble large mosquitoes with very long legs, eat very little, if at all. Adult crane flies live for only a few weeks, and when they find their...
