Vos plantes ne poussent pas correctement ? Les feuilles sont d\u00e9color\u00e9es ? Vous remarquez des petits insectes qui rampent ou volent autour de vos plantes ? Vous avez peut-\u00eatre affaire \u00e0 des pucerons. Cet article explique tout ce que vous devez savoir sur les pucerons : ce qu’ils sont, comment les reconna\u00eetre, les traiter et les emp\u00eacher de nuire \u00e0 nouveau \u00e0 vos plantes. <\/p>\n\n

Quels sont les pucerons ?<\/strong><\/strong><\/h2>\n\n

Les pucerons sont de tr\u00e8s petits insectes suceurs (moins de 4 mm) qui aspirent les nutriments de votre plante, l’emp\u00eachant de se d\u00e9velopper correctement et mena\u00e7ant tout votre jardin. Pour ce faire, ils se concentrent principalement sur la succion de la s\u00e8ve des nouvelles pousses. <\/p>\n\n

Les pucerons se propagent tr\u00e8s rapidement car ils sont tr\u00e8s mobiles (certains pucerons peuvent voler).<\/p>\n\n

En plus de sucer la s\u00e8ve de vos plantes, ils peuvent \u00e9galement transmettre des maladies d’une plante \u00e0 l’autre. En pr\u00e9levant la s\u00e8ve, ils peuvent \u00e9galement prendre la maladie de la plante et la transmettre d’une plante \u00e0 l’autre. <\/p>\n\n

A l’int\u00e9rieur, ils se reproduisent beaucoup plus rapidement car leur reproduction n’est pas arr\u00eat\u00e9e par le froid de l’hiver.<\/p>\n\n

Il existe diff\u00e9rents types de pucerons, qui s’attaquent \u00e0 toutes sortes de plantes, des rosiers aux plantes d’int\u00e9rieur, en passant par les arbres fruitiers…<\/p>\n\n

Comment reconna\u00eetre les pucerons ?<\/strong><\/strong><\/h2>\n\n

Les pucerons peuvent \u00eatre difficiles \u00e0 rep\u00e9rer en raison de leur petite taille (2 \u00e0 4 mm). Ils existent dans de nombreuses couleurs diff\u00e9rentes (noir, gris, rose, blanc) mais la plus commune est le vert clair (ce qui les rend particuli\u00e8rement difficiles \u00e0 trouver sur les plantes). Cet insecte se trouve g\u00e9n\u00e9ralement autour des tiges. <\/p>\n\n

Bien qu’il soit difficile de trouver des pucerons, si votre plante est attaqu\u00e9e, elle pr\u00e9sentera des signes tels qu’une croissance lente, des nouvelles pousses d\u00e9color\u00e9es, des feuilles recroquevill\u00e9es…<\/p>\n\n

Une autre particularit\u00e9 des pucerons est qu’ils cr\u00e9ent une substance collante qui attire d’autres insectes comme les fourmis, ce qui peut \u00eatre un signe de la pr\u00e9sence de pucerons.<\/p>\n\n

Comment traiter les pucerons ?<\/strong><\/strong><\/h2>\n\n

Si vous avez simplement affaire \u00e0 une petite infestation, retirez-les \u00e0 la main.<\/p>\n\n

En pulv\u00e9risant votre plante avec un jet puissant, vous pouvez d\u00e9loger les pucerons qui tomberont et ne retrouveront g\u00e9n\u00e9ralement pas le chemin de la plante.<\/p>\n\n

Si l’infestation est trop importante et que les pucerons ont d\u00e9j\u00e0 affaibli certaines branches, la meilleure solution est de couper cette branche (et les pucerons avec). Br\u00fbler les branches coup\u00e9es permet de s’assurer que les pucerons ou les \u0153ufs ne vivent plus dans votre jardin, et donc de r\u00e9duire le risque qu’ils s’attaquent \u00e0 une autre plante. Une autre m\u00e9thode naturelle pour se d\u00e9barrasser des pucerons est d’inviter des coccinelles, qui sont les ennemis des pucerons et peuvent s’attaquer \u00e0 plus de 15 pucerons chacune ! <\/p>\n\n

Comment \u00e9viter les pucerons ?<\/strong><\/strong><\/h2>\n\n

Qu’il s’agisse de maladies, d’insectes ou de parasites, la pr\u00e9vention est toujours la cl\u00e9. Il est important de garder vos plantes fortes et en bonne sant\u00e9 car elles pourront mieux lutter contre les pucerons, mais aussi parce que les pucerons ciblent surtout les plantes d\u00e9j\u00e0 faibles. <\/p>\n\n

Pour un jardin ext\u00e9rieur, les pucerons aiment stocker leurs \u0153ufs dans les mauvaises herbes, alors d\u00e9sherbez r\u00e9guli\u00e8rement votre jardin pour limiter les risques de pucerons.<\/p>\n\n

Faites attention au type d’engrais que vous utilisez sur vos plantes car un exc\u00e8s d’azote attire les pucerons.<\/p>\n\n

Enfin, bien que les pucerons s’attaquent \u00e0 un grand nombre de plantes, il existe certains ar\u00f4mes produits par les plantes qui repoussent les pucerons. Il s’agit notamment de l’oignon, de l’ail, de la ciboulette, de la cataire et de la coriandre. Une m\u00e9thode de pr\u00e9vention efficace consiste donc \u00e0 planter ces r\u00e9pulsifs pr\u00e8s des plantes les plus susceptibles d’\u00eatre attaqu\u00e9es. <\/p>\n","protected":false},"excerpt":{"rendered":"
