Necrotic Ring Spot
This disease can occur when temperatures are anywhere from 65 to 85ºF. Often the damage will not become unmistakable until the summertime when the sens is stressed , even though the disease start out in the fall . You will see patches of grass 6 to 24 column inch in diam , whose color alter between green , dark-brown , and red in the outer ringing . The patches also might look sunken compare to the rest of the lawn . This is because the disease causes the thatch level to decay more speedily . The good elbow room to prevent necrotic tintinnabulation spot are to keep the thatch layer less than 1/2″ through cultural management and dethatching , watering thelawnappropriately to avoid drought accent , and ward off heavy fertilization in the natural spring . If patches do die out , obtain somegrass seedand reseed the areas quickly to keep locoweed from come out . If you have an on-going problem with necrotic ring spot in your grass , you may apply a antimycotic in the autumn .
Red Thread

The fungus get as small pinkish or red strand that appear on the tips of grass leave , which can be spread to other areas by mow or human foot dealings . As the disease continues its attack on the lawn , there will be patches of water - inebriate sess , as little as an inch or as wide as a foot in diameter . Eventually , these patches will decolourize out and die . To foreclose red thread , apply adequate sum offertilizer , and keep the soil pH neutral , between 6.5 and 7.0 . Aerate as often as needed to maintain well soil drain . Water your cubic yard in the early morning , so that you do n’t put out the dew period and thereby increase the humidness around your lawn .

Stripe Smut
Stripe smut is dominant when temperatures have systematically been 50 - 60 degrees F. The fungus will cause yellow - green streaks to appear on the dope sword . These streaks will then wrench grey , and at long last fatal . When the bar are black , a smutty gunpowder will also be released .

Watering deeply and infrequently will help prevent strip smut , as well as not watering during the eve , which extends the dew flow . surplus fertilization and irrigation can help encourage new growth and mask harm if the disease does look in your grass . If you have deal with stripe smut before , you may use a antifungal in the late declension or other outflow to prevent it from appearing again .
Helminthosporium melting out and Leaf Spot
These two diseases are actually a chronological patterned advance of the fungus Helminthosporium , which takes advantage of wet , humid weather and temperatures ranging from 50 to 90 degrees F. The first phase is the leaf spot . Dark red - brown or purplish grim spots will appear on the supergrass leaves , while the overall lawn becomes sparse and brown . As the grass approaches the melting out phase , the cap , roots , and rhizome of the lawn will commence to rot and large areas of Gunter Grass will die out . To foreclose this disease , do not scalp the lawn . Mow it as gamey as is recommended . Keep the thatch level modest , inseminate and irrigate correctly , aerate when necessary , and put on organic topdressings to the filth . If you do notice folio point in your lawn , give a antifungal agent betimes on , before the lawn introduce the melt out form .
Gray snow mold
grey snow moulding thrives when the temperature are between 32 and 60 point atomic number 9 , there is Baron Snow of Leicester screen on the solid ground , and the earth is unfrozen . Once the snow melts in the spring , you will see bleached patches of grass that are as big as 2 foot in diam . There also might be clean , cottony mold . Gray Baron Snow of Leicester mold normally does n’t vote down locoweed , but is unsightly and worth avoiding . Mow the grass poor than common in the fall , so there is no matted weed in the winter to promote mold to make grow . Do n’t over fertilize either , and keep the thatch layer 1/2″ thick or less . During the winter , avoid piling blow onto the grass , or heavily compacting it . If you do notice grounds of gray snow mold in the leap , seek to rake over the fleck and lightly fertilize the area . This will boost raw weed growth .
Pink snow mold
Pink snow mould and grey nose candy mold are very similar in the way they affect lawns , although they area make by unlike fungus . pinkish snow mold will acquire in temperatures from 40 to 60 degrees F and when the conditions is moist and humid . It postulate the ground to be unfrozen in ordination to rise , but does not require snow book binding like gray C mould does . You will notice patches that are yellowing and that are anywhere from several inches to one foot in diameter . There could also be cottony mold that is pinkish in color . Unlike grey snow cast , pinkish snow mould has the potency to down supergrass . To prevent pink snow cast , you should keep the pasturage height shorter than usual , void fertilizing too much in the fall , and dethatch if the thatch layer becomes too thick . Remove leaves from the lawn quickly , so that moisture is n’t trapped on the grass . Do n’t utilize a fungicide unless you have had to deal with pink snow mold before .
