How Can I Get Rid Of The Powdery Mildew On My Cilantro?

There are several ways to get rid of the powdery mildew on your cilantro. Here are some of the most effective methods:

Remove infected plant parts as soon as you see them. Dispose of them in a sealed bag to prevent the spread of disease.

Disinfect your pruning shears by dipping them in a 10% bleach solution between each cut.

Remove and dispose of all the plant’s infected lower leaves. Cut off the leaves as low to the ground as possible to prevent the spread of disease within the plant. Make sure that you dispose of these cuttings in a sealed bag to prevent the spread of disease.

Make a solution of 1 part milk and 9 parts water. Soak all the plant’s remaining leaves in this solution for 5 minutes. Wring out the leaves and allow them to dry before reapplying any chemical treatments.

Treat your cilantro plant with a horticultural oil spray once per week. This should help to suffocate the fungal spores. Make sure that you reapply the oil after 7 days, since the fungicidal properties of oils break down within 7 days.

Allow the plant’s leaves to dry in full sunlight at least once per day. This will slow down the growth of the fungal spores.

Make a solution of baking soda and water. Use this to rinse your plant’s leaves at least once per day.

Make a fungicidal tea using 1 tablespoon of cloves to 2 cups of water. Allow this to steep for at least 6 hours, then strain out the cloves before using. Soak the plant’s leaves in this tea for at least 30 minutes before rinsing them with clean water.

Do this at least once per week.


What Else Can I Do To Prevent The Powdery Mildew From Coming Back?

While there are many ways to prevent the powdery mildew from coming back, one of the most important ones is making sure that you choose the right plant in the first place. While cilantro is a very popular herb, it is prone to attracting pests and diseases if you don’t take the proper precautions. Be sure to buy cilantro (and any other plants) from a reliable nursery. This will help you to ensure that the plants are free of pests and diseases.

Make sure that you choose a planting site that has full sun exposure, since cilantro does best when it receives a lot of sunlight. If possible, avoid planting your cilantro in low lying areas where the soil is constantly moist or flooded.

If you do have a problem with the powdery mildew returning to your cilantro plant, it may be worthwhile to grow another type of herb instead such as chervil, coriander, dill, or fennel. These herbs are similar to cilantro in taste and appearance.
