What is a summer patch?
Summer patch is a kind of disease that affects some kinds of lawn, especially Pao pratensis or Kentucky bluegrass, Poa Annu or annual bluegrass and some species of the Festuca family. It is also known as the POA patch, most likely, referring to the Travs family, which often affects. These diseases often appear to be circular or crescent spots of pale, dry grass, which eventually die if they do not cure, leading to bald places. In the annual bluegrass, the disease has a "frog" that has a small spot of green grass in the middle of a straw ring of grass. Some places covered with grass that can get a summer patch include golf courses, sports fields and homemade lawns. The sponge commonly occurs in the soil and in fact does not attack the grass until some external factors, one of which is hot weather. MagnaPorthe Poae Speciformally damages the roots of the plant and creates dark strands called hyphs that can be seen microscopically. If they are observed by the naked eye, the plants will be thatThey are infected with a summer patch, show thin and less root springs that look more uncroppy or dead.
As the name suggests, the summer patch prevails in the summer season from June to September. This is because the high temperature prevents infected roots from maintaining grass and providing enough water. The soil, which has temperatures between 65 and 70 ° F (approximately 18 to 21 ° C), is sensitive to the sponge, especially if the air temperature is approximately 90%of degrees; F (about 32%degrees; c) or warmer. Mushrooms often thrive in humid and humid places, so the ground that are regularly maintained and connected, such as golf courses and designed landscape, are more at risk of obtaining the POA patch. Other factors, which are insufficient that the disease is insufficient drainage, lack of air circulation and if the soil is strongly compressed.
To avoid summer patch or to prevent further infection of TRThe soil must maintain the pH in the range of 6.0 to 6.5, because the slightly acidic pH is not favorable to the fungus. This can be done by nourishing the soil with some nitrogen. Frequency and quantity of irrigation should also be reduced and a drainage system can also be installed to release excessive humidity. If possible, the soil may be oran to reduce the compaction and introduction of the correct air circulation. Fungicides can also be used if the summer patch has already expanded, although it is more effective as a preventive tool.
