Powdery Mildew – Effects on Plants

powdery mildew

What is powdery mildew?  Many of those who do agriculture and growers alike have a vague idea as to what a plant infestation presenting itself in the form of a powdery mildew truly is.  And nearly all those who have gardens would more than likely recognize if they were to have a powdery covering on the surface of their plant leaves.  But what, exactly, is powdery mildew?  Where does it come from and what can you do to rid your garden or crops from this potential plant killer?

Powdery mildews are fungal parasites that invade, infest and then feed on the leaves of your plants.  They affect any number of plants and their effect can greatly vary depending on the concentration of the infestation and how it is treated in addition to the type of plant that is being attacked.  The fungus grows on the surface of the infected leaves with an invasive growth as it is restricted to the epidermal cells.

The leaves that are plagued with this will more than likely have a slowed or lessened rate of photosynthesis. The reason for this is that the cells on the surfaces of the leaves are under fire, and this greatly reduces both the efficiency of photosynthesis as well as the amount of sunlight that is available for the process of providing energy.

The stomata are also affected in how they are able to perform gas exchange, and this also affects the health of the plant as it slows down the process of respiration for the plant. CO2 gas exchange is hindered with the presence of a powdery mildew.  This is a problem for plants all across the continent and it is something that virtually every plant is susceptible to.  However, the term “powdery mildew” is more like a category of plant infestation as there is a very long list of different fungi which can attack your plant.  This also makes a difference in the severity of the infestation. ornamentals, such as beebalm (Monarda), lilacs (Syringa), zinnias, roses, garden phlox (P. paniculata) and cannabis.  It also affects vegetables, including beans, cucumbers, grapes, melons, and squash.

These fungal spores which transport these pests are typically spread through the wind and can also be transmitted overwinter on plants and even in the plant debris.  Powdery mildew does not need to be in direct contact with water to be able to grow and attach itself to a host surface.  The late summer makes for a perfect storm of sorts in the growth and dispersal of these fungal spores as the days are warm and the nights are cool.  And it can have a wide variety of effects on the plants that you grow at home.

Powdery mildew can affect the flavor of fruits or vegetables that you grow at home, in addition to drastically reduce the yield of fruit that you get in the first place.  These are just a few of the things that can be affected with the powdery mildew infestations.  However, there is a way to be able to successfully treat and reduce the growth of pests on your plants from here on out.  Regardless of whether or not you have suffered from this in the past, we have a way to be able to overcome it and get on top of it for the future.  With Dyna-Gro Pure Neem Oil, you will be able to effectively control and take pests out of your garden.  Using this in combination with our Pro-Tekt® formula is one of the more effective ways to be able to manage pest infestation in your garden and ensure that your plants grow healthily and protected from these fungal infections.
