Nelson: Magnaporthe poae: bluegrasses, fine fescues: circular, yellow or tan areas of dead and dying plants approximately 1 foot in size; can have green, obviously healthy plants in center; roots, crowns, and stolons have dark brown fungal hyphae on them; vascular staining and cortical rot occur in later phases: heats (> 85) in late spring through the summer; most severe when grass is mowed low or when soil moisture is excessive: aerate soil and apply slow-release nitrogen; improve drainage; decrease compaction; water proper length of time; do not trim too low; control thatch; lower soil pH if higher than 7: systemic fungicides in fall typically needed when disease has been serious For presently registered fungicides, see Bug Management Guidelines: Turfgrass.

There is no one best turfgrass suitable for all yards. The type of turf you pick for your lawn must work with your climate, prepared for use and maintenance level, and visual desires; it likewise needs to have some resistance to common illness. Cool-season grasses (e.g., bluegrasses, fescues, ryegrasses, and so on) carry out best at daytime temperature levels between 70 to 85F.

Frequently, illness most effect turfs when they aren't intensely growing. Cool-season grass is more susceptible to disease problems during the summertime, while warm-season yards are more vulnerable to illness in late fall through early spring.

New and improved cultivars of yard turfs providing greater illness resistance, color, texture, density, and harmony have been developed the previous a number of years. Contact a reliable nursery or the UC Cooperative Extension office in your county for particular recommendations.

Recognising Common Outdoor Pests Effectively

Much of California has a Mediterranean climate identified by rains in winter and spring and really little rain during summer season and fall. Throughout the state, yards require irrigation.

Using excessive or not adequate water can result in unhealthy, slow-growing yard that is susceptible to pathogens. Waterlogged soils are poorly aerated, which restricts root development, promotes some diseases, and permits algae and moss to flourish. In general, a deeply watered yard establishes a deeper and more substantial vertical root system, which supplies it with higher drought and illness resistance than a shallowly watered lawn.

Warm-season turfgrasses are more drought-resistant than cool-season lawns and require about 20% less water. See Table 2 for details on the number of minutes to water warm- and cool-season lawns each week in different parts of California, based upon the output of the irrigation system or hose-end sprinkler. It is best to water the lawn completely at longer periods, until runoff simply begins, rather than watering a little every day.

What Diseases Are Attacking Your Lawn?

If a lawn needs 40 minutes of watering each week however overflow begins after 20 minutes, water two times a week for 20 minutes. In cases where soil uses up water so slowly that overflow happens before 10 minutes, water cycling is needed. To cycle, water up until overflow just begins, turn the system off, and repeat the process in thirty minutes before the soil surface dries.

To figure out sprinkler output, conduct "catch can tests" by setting little, empty, straight-sided, equal-sized containers such as tuna or feline food cans on top of your yard every 10 to 15 feet between sprinkler heads operated by the very same valve (Fig. 2) and run the system for 15 minutes. After 15 minutes, shut off the system and measure the quantity of water in each can with a ruler to figure out the average amount of water per can.
