Lutte contre les pucerons verts dans les vergers de mirabelliers et de quetschiers conduits en Agriculture Biologique

Abstract : Organic tree culture is a challenge, knowing that only a few substances are allowed in the EU, and most of them are not very efficient. The green aphid on plum tree (Brachycaudus helichrysi Kalt) is one of the many harmful insects that causes quality and quantity loss on mirabelle and quetsche plums. But it can also transmit « plum pox » from one tree to another, a virus that causes the death of trees in a few years. To prevent those problems, it is important to get to know the cycle of this insect and what conditions causes it to develop. This will enable producers to adapt their treatments. Moreover, china clay and neem oil are two authorized products in the EU, but they are not approved in France. This study is about testing preventives strategies for those products, to complete the previous years of trial and to find a way to improve their efficiencies. The result of spring preventive treatments didn’t get results in 2015 due to the lack of aphids mostly. The temperature of some month can now help us to get to know if the attack is going to be important. The study enables us to improve the anticipation of an infestation.
