Trade mag reads

Did you read your latest IGIN? The IA mag. If so you would have found two lawnsiters. The fact nobody has mentioned it yet tells me all I need to know about how well those mags are read.

The south and west version of TURF due to come out? Be sure and read it puhleeze.

You need the read the stories to find the other LSer.

I picked up some new customers. Not sure if it was the ad or search engine.

sadly peter, i did not see your ad. i have seen a certain rainbird lover in there periodically.

i find the articles geared more for the novices and landscapers that are more on the fringe of the industry. for those that are in the trench everyday, it is lacking depth.

July on-line is not out yet but i will make sure you know when it does. The June TURF has a good article for irrigators. Never hurts to be smarter than the on-site landscaper.


TURF SCIENCE
The Relationship between Irrigation and Pest Control

by John C. Fech

One of the most obvious IPM components in terms of pest control is the advent of disease-resistant cultivars of turf and ornamental plants. One needs only to participate in a field day at a land grant university turfgrass research facility to quickly understand their influence. Some IPM components are not so readily observable. The influence of irrigation on pest populations and pest control efficacy is a good example.


Excessive thatch can reduce the effectiveness of pesticide applications by facilitating runoff, especially on a slope.

Surface leaf moisture
Certain foliage diseases of turf and ornamental plants require ďfree moistureĒ on the leaf surface for the spore to germinate and infect the plant. For example, the common disease leaf spot/melting out of turf is caused by a pathogen (actually two closely related pathogens) that is favored by dry periods that alternate with prolonged cloudy, wet weather. Under favorable conditions, an abundant number of spores are produced and are spread to uninfected leaves via wind, mowers and other turf equipment, splashing water, foot traffic and infected grass clippings. They germinate when they come into contact with water droplets on the leaf surfaces that remain for more than four hours.

The conditions required by leaf spot and most other foliage diseases to become a pest in the landscape are worsened through poor irrigation procedures/timing. When trying to lessen the spread of these diseases, itís important to water in the early morning hours so leaf surfaces can dry during the daytime. Late-evening watering tends to extend the natural period of leaf wetness, increasing the likelihood that infection will occur. When watering ornamental plants, using drip irrigation to avoid wetting the foliage altogether is a technique to consider.

Life down under
The growth of a healthy root system is vital to the overall success of the landscape. Hidden as it may be, roots comprise half of the plant tissues and must be alive and thriving to resist pests. Both insects and diseases can cause degradation of the root system.

One of the key factors in white grub population growth is the relative ease of egg laying by the adult, or oviposition. Ideally, you want the soil to be moist enough for the turf plants to have the capacity to draw the water it needs, yet dry enough to resist oviposition. Keeping the soil moist is a function of monitoring soil moisture and adjusting controller run time accordingly. On the other hand, underwatered turf will exhibit pest damage from insects such as sod webworms and bluegrass billbugs sooner than healthy turf, and will be slower to recover after insect or mite injury. Underwatered shrubs, perennials and ground covers respond similarly.

The level of soil moisture can also affect fungal diseases such as Pythium blight. The two most influential conditions for occurrence of Pythium blight are poor soil drainage and a wet turfgrass canopy. Waterlogged soils along with high relative humidity and very warm daytime temperatures provide the ideal environment for its development.


As an irrigation audit is conducted, obvious flaws can be identified and marked for repair or replacement.
Influence of thatch
Excessive thatch can also enhance the development of Pythium blight. Layers in excess of .5 inch can act as a retaining agent for waterlogged soils, holding too much water and not allowing adequate oxygen exchange.

Under drier than optimal conditions, the opposite effects take place, with the thatch layer serving as a barrier to the infiltration of irrigation water. This is especially visible in landscapes where the turf is sloping and the water is encouraged to run off after an irrigation event, decreasing the time necessary for adequate infiltration.

In general, thatch accumulations of more than .5 inch reduce heat, cold and drought hardiness, and increase the incidence of localized dry spots, scalping and pest problems. As thatch accumulates, there is a tendency for root growth to occur in the layer of thatch rather than the soil. This is problematic, as the turf will become poorly rooted and prone to stress injury and damage from pests.

Weeds are pests, too
Broadleaf and grassy weeds can be controlled through IPM methods. The best defense against weeds is a thick, dense, well-managed turf that can compete with weeds for light, nutrients and water. When turf stands thin, management strategies should be analyzed, including the application of herbicides to suppress or kill unwanted plants.

After applying a preemergence herbicide, itís wise to water the product in with at least a .5 inch of water to move the herbicide off the leaves, through the thatch and into the zone of activity, the upper 2 to 3 inches of soil, where germination occurs. This should be done evenly for best results.


In the absence of a thorough irrigation audit, the tendency is to irrigate for the dry spots.
Postemergence herbicides should be utilized differently. Itís best to avoid application of postemergence herbicides to turf and weeds under heat or drought stress as injury may occur. Water the turf thoroughly before application to assure weeds are growing actively, but unlike with preemergence herbicides, avoid irrigation for several days after application, as watering can wash the herbicide product off the leaves of the weed.

One overall factor
Problems dealing with root dieback, leaf moisture, thatch, runoff and weed control can be greatly lessened through an irrigation system audit. It has been documented that most landscape clients who control the frequency and run time of their systems tend to irrigate for the dry spots, meaning they simply allow the system to run until the entire turf area is green, regardless of irrigation uniformity.

In some scenarios, both with turf and landscape irrigation, distribution uniformity can be quite inefficient. This is most obvious when an audit is conducted.

The first step in conducting an irrigation audit is to turn the system on and watch it run. Look for obvious flaws such as heads that donít turn, pop up or spray the street. Water spray deflected by plants that have grown larger since their installation is another commonly ignored flaw. These limitations will reduce the effectiveness of pesticide applications, such as preemergence herbicides that require uniform application of water to be effective.

Next, set out collection devices (tuna cans work great) near and between irrigation heads and run the system for 20 minutes to measure how much each head puts out. Make notes of any discrepancies that exist greater than 20 percent and replace/repair as appropriate.


As plants grow, they can encroach and deflect the output of irrigation heads, leading to the inefficiency of pesticide applications.
Changes in landscape design
In addition to repairs in the irrigation system, itís important to consider adjustments to the landscape design. As groups of plants, each has differing needs in terms of water and nutrients; generally, most ornamentals require a third to half as much as turf.

Instead of colocation, work with your clients to establish various irrigation zones in the landscape. Commonly, a high-maintenance zone will be placed near a building entrance, the front door to a residence, back patio spaces and other visible and highly trafficked areas. After these have been identified, a medium-maintenance zone and a low-maintenance zone are natural designations. In addition, avoid a single station that waters both sunny and shady areas, as the water needs will be different in each. At the very least, separate the turf from the ornamentals by establishing mulch beds that connect ornamental plants in a grouping, rather than being dispersed throughout the landscape space.

The article is written more to address C3 verse C4 turfgrasses and associated pathogens.
Overall, not bad advice for those lacking in certain agronomic skills.
I agree with Drought on his one comment regarding a lack of depth in trade magazine articles.
When I get certain rags, I mean mags, I'll leave them around for the crews to read but have found only NTEP based articles
worth reading.
All of that said, throw in a couple of hot bodies chicks and some cold beer and you'll have my attention until the beer runs out.

Based on my pull vs trench thread I think we get more northern irrigators here.

My theory on my IGIN ad was exactly as you described. I put it in the far back figuring it would get tossed on the ground. I took the magazine and dropped it on the ground multiple times. In my dropping I discovered that it would land either with the first page showing or the back page showing which is where my ad is. Maybe I can add a Daisy Mae with pigtails?
