The arrival of spring doesn’t just wake up in the vegetation. If the first vegetables to germinate, if the cherry blossoms are flowers, so the roses reveal their future buttons, and other inhabitants of the garden, much less sympathetic, also make their grand return. It is enough to open the eye… The blister boursoufle already the young leaves tender green of peach, otiorhynques began to nibble by night those of the lilac, the slugs have devoured in some places the seedlings in salads and chestnuts are pointing the tip of their nose at the foot of the raspberries… all without prejudice to future attacks of downy mildew ( Phytophtora infestans ) that, in the summer, can completely destroy the crops of tomatoes or potatoes.

there’s Nothing new under the sun, you might say. Except that with the ban on gardeners using synthetic pesticides, in force since 1 January last, a good number of them may, if they do not keep, they may find themselves strong-nots, at the first outbreak coming.

“The parasite will not abandon the garden under the pretext that the new law applies”, noted quite rightly, this week, Nicolas Marquet, director-general of the Union of companies for the protection of gardens (UPJ) at a press conference. However, a recent survey*, commissioned by the professional association that brings together 26 companies in the sector, tends to show that the “troops” have not really been aware of the new situation.

indeed, solutions of organic and related (the only ones authorized now) with no, or little curative action, in contrast to the synthetic pesticides now banned, the fight against parasitism is essential to the observation and prevention. This requires strong knowledge (know how to recognize parasites, use good agronomic practices, decide when they exist-tolerant varieties…) and a lot of time, for a result that is significantly more random. Not to mention the cost, often prohibitive of the proposed solutions…

Fortunately, many organizations have not waited for the deadline of 1 January to help gardeners not to get overwhelmed. For the past two years, the application “The clinical plants” of the UPJ is downloadable on a smartphone, so searchable on the field. As soon as a problem presents itself, this tool is very simple to employment, establishes a diagnosis, photos, in just four clicks and offers solutions that are prophylactic and biological, that are compatible with the new regulation. If the intruder is not identified, it is possible to contact by e-mail a specialist of the health of the plants, or “phytiâtre”, which will provide a personalized response.

The national Society of horticulture of France (SNHF), in charge of the departmental program “Gardening differently”, offers the same type of service with the downloadable application VigiJardin, is hosted on the website of the national Institute of agronomic research (Inra). For its part, the topic garden, Figaro’s now offers a forum in which you can ask your questions, share with other internet users and get, we hope the answers to the difficulties you are experiencing.
