In the garden, we already have to deal with many harmful insects and pests (aphids, slugs, Colorado beetles, etc.) for our shrubs and plantations of all kinds. And unfortunately, as if that were not enough, all kinds of diseases also lurk in the vegetable garden (mildew, powdery mildew, alternaria, peach leaf curl…), which can leave some vegetable plants and fruit trees in a bad state. This is particularly the case of fungicidal diseases which deposit their pathogenic spores everywhere if nothing is done to stop the advance of the disease using conventional fungicidal phytosanitary products or one of those good old grandmother’s decoctions in spray to fight the fungi that take over all parts of the plant. However, a disease in a plantation is always taxing on plants (and gardeners!). So, discover some gardening tips and tricks to avoid diseases in the vegetable garden.
And in this regard, there is no need for chemicals in the crops! You can save your harvest with a few good gestures, common sense and environmentally friendly products.
1) Some good basic actions to avoid diseases in the vegetable garden
To ensure good air and sun circulation inside the plants, it is crucial to always ensure that space the feet well and prune the stems as well as the protruding leaves. This will create conditions less conducive to the development of fungal disease. In addition, whether we have had an illness or not, practicing crop rotation is crucial. This makes it possible not to impoverish the soil, but also, and especially not to let a virus or a fungus proliferate on the same plant from year to year. So avoid keeping the same plantation on a plot of land for more than two years in a row. Finally, if diseases appear in the garden, remove the parts and leaves affected by gray rot or brown spots. from the first symptoms. Then, remember to burn the dead leaves well and disinfect tools pruning used on a diseased plant with 90 ° alcohol. This will remove the bacteria and prevent the spread from the pruning shears.
2) Water at the base of the plants and not the foliage
For the sake of speed, we can sometimes do a little less well! However, the leaves of our tomatoes, squash, beans or eggplant tend to be rough. Result: they retain moisture better, which is conducive to the development of the main fungal diseases in the vegetable garden that we want to avoid. Whether with the hose, drip or porous hose, water the foot of the plants. In addition, avoid watering too late : the soil may remain wet all night. And that’s what microorganisms are waiting for to proliferate!
3) Choose the right varieties and maintain them
Already, if a chosen variety turns out to be sick, do not hesitate to change it the next time, even if it means opting for more resistant seedlings. If you live in a cold region, prefer early tomatoes. As for hot regions, avoid the hot weather on the plants by favoring spring and autumn / winter varieties for your peas, leeks, and spinach. In short, take into account the location of your garden to take the right fruits and vegetables. After that, never neglect watering and fertilizer to keep your seeds vigorous and resilient. An organic fertilizer, for example, will allow smooth balanced growth. Finally, think about natural tonics to stimulate the growth of young plants. This includes in particular plant extracts such as nettles or comfrey.
4) The right products to prevent diseases in the vegetable garden
Applying the right actions is one thing. Nevertheless, receiving a helping hand with a few garden protection products is never a refusal.
The solution with horsetail extract acts against mildew, against powdery mildew, against rust and more generally against diseases linked to parasitic fungi. It is diluted in rain or spring water before spraying it on and under the leaves.
Sulfur for powdery mildew treatment
In the form of powder or liquid to be diluted, sulfur is a preventive and curative fungicide useful in the fight against scab, erinosis, but also powdery mildew. It is simply to spray on the affected plants to treat them. Be careful, above 28 ° C, it becomes toxic. And below 15 ° C, it is better to prefer copper.
Copper for the shock treatment of mildew
Much better than Bordeaux mixture, copper hydroxide to be sprayed as prevention or every 8 to 10 days as a treatment to fight downy mildew on plants.
