Vegetable diseases in summer
The most known of the diseases and the most formidable for the vegetable garden is, without hesitation, downy mildew. Similar to a fungus, this disease causes brown spots on the leaves and stems of plantations. The worst part is that the fungus is extremely contagious. It is found most of the time on potatoes, tomatoes, strawberries and vines.
Among the diseases of the vegetable patch, there is also moniliosis. This highly contagious fungus forms brown spots covered with white dots. It affects fruit from the orchard such as apple, pear, apricot and peach trees.
Another vegetable disease that occurs at the end of the summer period: powdery mildew. It manifests as spots of white powder and quickly covers all the leaves. It mainly attacks roses and cucurbits. As for rust, it is recognized with the appearance of small rust-colored warts on beans, onions, leeks and certain aromatic herbs such as parsley.
How to fight against these diseases?
Here are the right things to do if any of these diseases invade your vegetable patch.
- Fight against mildew: know that this fungus cannot be cured. The only way to avoid it is to ensure a preventive action for your plantations. In the immediate future, you can opt for a copper-based treatment (such as Bordeaux mixture) before and after each rain. By blocking the germination of spores, copper will help protect future leaves. In any case, do not hesitate to bring a plastic film to protect your crops from the rain. If the fungus is already present, remember to cut the affected leaves and stems and then burn them.
- Fight against powdery mildew: just like mildew, you must stop the progression of powdery mildew immediately. In addition to cutting and burning the affected parts, you can spray a treatment based on natural sulfur or special baking soda in the garden. Repeat the operation every ten days.
- Fighting moniliosis: once again, the fight against this disease must be preventive. In addition to good lightening, you can also apply Bordeaux mixture in wet weather. Do not forget to remove damaged fruit that has hung on the trees in your orchard. Remember that the simple contact of a sick fruit can lead to the contamination of a healthy fruit.
- Fight against rust: your affected plantations should only be treated in case of intensive invasion. If the disease has not yet spread, simply start by cutting and burning the affected parts. Also, avoid excess water so as not to promote the humidity necessary for the development of this bacteria.
Generally speaking, mulching is an excellent tip for preventing the appearance of bacteria. Plant waste or natural straw are your best allies to protect your vegetable garden during climate change.
