Curative fungicide for dollar spot. Curative fungicide is a mixture of fungicides to cure dollar spot on golf courses. This spray can be used as and when required. With more than 35 years of experience in treating diseases, we guarantee to help you quickly and effectively with this disease without the need to replace your turf. Dollar spot disease can be found on all grasses and is characterized by brownish-yellow spots with irregular margins that are 1/16 to ¼ inches in diameter. The spots have a dark brown to black ring around them with a light tan or straw-colored halo, which creates the common name ‘dollarspots’ for this lawn disease. The lawn with dollar spot is usually speckled with numerous crooked yellowish lines made up of the fungal spores that have fallen from the leaf blades. Dollar spot, caused by the fungus Sclerotinia homoeocarpa, is the most common foliar disease of turfgrasses in the US. The fungus can cause a white or yellow patch on turf. Yellow dollar spot has generally been found to be more serious than white dollar spot. Dollar spot is one of the most common turfgrass disease. It is also one of the most recognizable because of its’ symptoms. Dollar spot is also known as brown patch, rough patch, lesion patch and many other names. It appears as a dark brown to black circular lesions with a light tan edge. These lesions will usually turn gray before they become corky or dome shaped.

Curative Fungicide For Dollar Spot

Introduction

Dollar spot can be both a serious disease and an aesthetic problem for many turf managers. The fungus responsible for dollar spot thrives in warm weather, making it a frequent nuisance on golf course fairways and other areas of dense turf. Dollar spot is known to cause stress on turf, which can lead to increased management costs and possible loss of playability. Treating dollar spot demands aggressive control measures that are consistent, reliable and affordable, especially in areas such as the Pacific Northwest where humid conditions promote rapid disease development. LaetaOP fungicide is the only curative fungicide that provides up to 4 weeks residual control of dollar spot — even after rain or irrigation. Thanks to its novel active ingredient, LaetaOP penetrates leaf tissue faster than other curatives for fast symptom reversal and greater efficacy against this widespread disease. It’s also easy to use; manage dollar spot with just one application every four weeks.

Dollar spot is a frequently occurring fungal disease that can cause stress on golf course, athletic field and landscape turf.

Dollar spot, also known as brown patch or Sclerotinia blight, is a fungal disease that can be a frequent problem on golf course, athletic field and landscape turf during warm weather. This disease is caused by the fungus Sclerotinia homoeocarpa.

Symptoms include small circular tan or brown spots with dark centers that range in size from 0.25 to 2 inches in diameter. These spots may merge together forming large areas of dead grass that are light colored compared to healthy turfgrass. In addition to the appearance of these lesions on the turfgrass leaf blades there will be little or no signs of greening up even under favorable conditions (such as adequate moisture).

The disease is caused by the fungus Sclerotinia homoeocarpa.

The disease is caused by the fungus Sclerotinia homoeocarpa. This fungus lives off of dead plant tissue and is a plant pathogen, not a human pathogen.

It is primarily a problem during warm weather, when temperatures range from 65 to 85 degrees Fahrenheit.

This disease is primarily a problem during warm weather, when temperatures range from 65 to 85 degrees Fahrenheit.

Dollar spot usually develops first in thin or weakened areas of turf.

The disease is caused by the fungus Sclerotinia homoeocarpa, which survives in soil as small black fruiting bodies called sclerotia. These sclerotia may remain dormant until they are activated by environmental conditions such as excess moisture or a decrease in temperature. In warm weather, the fungus spreads from these sites to other areas of turfgrass by infected stolons (above-ground runners) and rhizomes (underground stems). The pathogen also can spread through movement of infested sod or plugs.

Sclerotinia blight symptoms include brown lesions with distinct margins on leaves and stems; small, dark spots on leaf tips; and dead patches within a lawn that occur irregularly for one to two weeks during warm weather periods (often May through September). Other fungal diseases may resemble dollar spot symptoms but typically do not have distinct margins around the lesions.

Early symptoms include small, round to oval spots about the size of a silver dollar (one inch).

Early symptoms include small, round to oval spots about the size of a silver dollar (one inch). The disease is caused by the fungus Sclerotinia homoeocarpa. Dollar spot is more common during warm weather, but it can occur anytime that air temperatures are above 60 degrees F and relative humidity is over 70 percent for several days. The disease usually develops first in thin or weakened areas of turf, such as bare spots that have been damaged by traffic or improper mowing.

These spots appear bleached as grass blades turn yellow and brown, but the turf remains alive.

The disease is caused by a fungus. The disease is most common during warm weather, when grass blades turn yellow and brown, but the turf remains alive. It’s also more common in thin or weakened areas of turf, such as between lawns and sidewalks or where water splashes up onto the lawn from sprinklers.

Symptoms may consist of grayish brown areas that are one quarter to one inch in diameter.

When the disease develops in spring, symptoms may consist of grayish brown areas that are one quarter to one inch in diameter.

The spots develop on lawns in the form of small, round to oval spots about the size of a silver dollar (one inch). The grass blades turn yellow and brown but the turf remains alive.

LaetaOP fungicide is the only proven curative fungicide for dollar spot that provides up to 4 weeks residual control, even after rain or irrigation.

LaetaOP fungicide is the only proven curative fungicide for dollar spot that provides up to 4 weeks residual control, even after rain or irrigation.

LaetaOP is a unique formulation of phosphorous acid and potassium bicarbonate in a low-odor solvent carrier. This formulation provides excellent activity against dollar spot on cool season grasses such as Kentucky Bluegrass, Tall Fescue and Perennial Ryegrass when applied at 0.25 – 0.5 lbs/1000 sq ft or higher rates of 0.50 lbs (1 oz)/1000 sq ft or higher; this includes applications made under stress conditions like drought stress and heat stress.* LaetaOP is labeled only for application during the growing season in most states, but it can be used up until frost if temperatures are above 50°F for three days prior to application.*

• The efficacy of LaetaOP may vary with environmental conditions such as temperature, relative humidity and sunlight exposure (excessive sunlight will cause rapid degradation).

LaetaOP fungicide uses a novel active ingredient that controls the disease by inhibiting sterol biosynthesis within the fungus.

LaetaOP fungicide uses a novel active ingredient that controls the disease by inhibiting sterol biosynthesis within the fungus. This reduces the rate of cell division and, as such, is effective in controlling dollar spot while also providing residual control. Application timing is crucial when using LaetaOP because it needs to be applied before or at the time of initiation of symptoms.

In general, fungicides are best used as part of an integrated management plan that includes irrigation and rainfall management strategies. For example, irrigation helps reduce leaf wetness which prevents infection through splash contamination during rain events; however, excessive irrigation can increase disease severity by creating conditions favorable for fungal growth (i.e., warm temperatures). Rainfall management involves both preventing overwatering and reducing runoff water after rainfall events so that it doesn’t carry infected leaves back into plantings where they can reinfect healthy plants.

LaetaOP fungicide is proven effective against dollar spot with just one application every four weeks — even after rain or irrigation

LaetaOP is a curative fungicide that controls dollar spot with just one application every four weeks. It contains the active ingredient fluopicolide, a compound that inhibits sterol biosynthesis within the fungus. This results in weakened fungal cell membranes and reduced growth of hyphae, which decreases disease symptoms on turfgrass leaves.

The efficacy of LaetaOP has been demonstrated with numerous trials in various locations throughout the United States. In these trials and others, LaetaOP provided consistent control at recommended label rates through various weather conditions including rain or irrigation.

Conclusion

LaetaOP fungicide is a curative and preventive fungicide that kills dollar spot fungi, even after rain or irrigation. LaetaOP offers the longest residual control of any dollar spot fungicide on the market — up to 4 weeks. It is also labeled for use on golf courses, sod farms and athletic fields, making it an ideal solution for your turf needs.
