Preventive Fungicides: How They Work

Contact fungicides are sometimes called residual fungicides. This term describes the ability of these products to remain on the plant surface for several days after application. During this period, they offer continued protection against fungi. They are therefore prophylactic against a number of fungi species that cause lawn diseases.

The preventive benefits offered to plants remain as long as the fungicide doesnt get degraded by environmental elements such as sunlight or washed off by irrigation, wind, or rain. Repeated applications are therefore essential to ensure that the fungicide stays on the plant and continues to provide protection from fungi.

How To Tell If Your Lawn Has A Fungal Disease

Your lawn is an ecosystem comprised of a vast multitude of organisms, including fungi. When everything is in balance, fungus will not grow. However, several factors may disrupt this equilibrium, causing fungi to overrun your lawn and consequently become a problem.

Various factors have been found to encourage fungal overgrowth on lawns. These include:

  • Improper mowing, particularly very low mowing
  • Overwatering
  • Planting grass strains that are susceptible to fungal diseases
  • Elevated temperature and humidity
  • Drought

  • Parts of the lawn that may appear darkened, slimy, wet or gray
  • Black, purple, grey, orange or red spots on the blades and/or stems of the lawn grass

  • The environmental conditions favor fungal growth and proliferation
  • The homeowner fails to take the appropriate countermeasures against the lawn fungus in good time
