Homemade spray against tomato mould

It is in August when we usually experience the highest temperature differences. These changes are caused by frequent alternation between heat and rain and this promotes development of various fungal diseases. Unfortunately, tomatoes, cucumbers, zucchinis or eggplants are especially susceptible to mould. Surely you do not want your year-long efforts destroyed by fungal diseases. Fortunately, there are methods you can use to protect these rather gentle crops.

Recognize mould as soon as possible

Fungal disease on tomatoes is easily identifiable as the mould mainly appears on leaves in the form of dark spots. These spots expand over time, eventually killing leaves. Unfortunately, the mould also affects fruits which become soft, brown and eventually dry up. First, the disease affects the original plant but later it also spreads from plant to plant and may destroy a significant part of your harvest.

Types of fungal diseases

Tomatoes are usually affected by two types of mould: potato blight (Phytophthora infestans) and grey mould (Botrytis cinerea). Potato blight is very inconspicuous at first. Leaves appear as if they are burned by the sun (they are dry, brown). Gray mould also attacks tomatoes, peppers, peaches or strawberries. As the name suggests, this awful mould is grey. If you notice these signs, you need to dispose of any infected parts of the plant as soon as possible – tear them off and burn them or throw them in the trash – before the mould spreads further.

Prevention is important

The first step is prevention and it should begin at the start of the season: when you choose the location for tomatoes, make sure it is not in close proximity to potatoes, peppers or zucchinis. Also avoid location where you had potatoes in previous years. A lot of sun is very important. Water in the morning and avoid the leaves, aim directly on roots. Tie up plants to prevent contact with moisture. Leaves must not touch the soil. Clip off sucker regularly.

Plants that prevent mould

You may try plants that help you fight moulds. Plant them or place them near tomatoes. These plants include the common marigold, basil or velveteen. You may also apply sprays and infusions.

Garlic infusion

Garlic infusion is easy to prepare. Peel a few cloves of garlic and chop them finely and put them in a jar. Pour one litre of boiling water in and let it infuse overnight. Drain through a strainer and put in a spray bottle. Apply every other day.

Horsetail extract

Collect horsetail (about 2 handfuls) and pour one litre of boiling water over the stems. Let it sit overnight and drain. Pour in a spray bottle and apply.

Baking powder

Mix 1 teaspoon of baking powder in one litre of water and add few drops of vegetable oil. Pour in a spray bottle and apply every third day.
