Global warming, among other causes, makes cases of damage caused by new pathogens in crops of any type increasingly frequent, and which a few years ago were only known in specialized literature on these topics. The poplar is no stranger to this problem, pests such as the Woolly Aphid whose presence in Castilla y León has increased in the last 10 years and which attacks with special virulence Euramerican clones (I-214, Mc, etc...) of “ rough bark.” In the case of Inter-American clones such as Beaupre, Raspalje and Unal, there are other pathogens that condition their cultivation.
Especially fungi such as Melampsora (Rusts) that affect the leaves, and Fusarium sp. (Cat Scratches) that affects the root, attack significantly and especially in the first years of the tree's life, and can cause serious damage in certain areas where the climatic and edaphic conditions make the attack of said fungi viable. logs It is also observed that borers (Paranthrene tabaniformis and Cryptorhynchus lapathi) attack thes Peru Email List inter-American clones more avidly in the first years of life. As with agricultural crops, poplar clones have their strengths and weaknesses against certain pests and diseases (resistance, tolerances).
The most effective measure in response to this problem that is increasingly present in our geography is clonal diversity, that is, using different productive clones of both Inter-American and Eur-American species, and thus trying to stop the advance of said pathogens, in addition to enabling a faster and more effective response to the presence of a particular pathogen in a specific area. leaves It is more than convenient to change that image of monoclonal cultivation that was populculture long ago, in which hundreds of hectares were planted with a single clone, resulting in zero genetic variability, incapable of stopping the advance of any threat that arose.
