Sweet cherry is attacked by a range of viruses and none of them can be cured once a tree is infected. PNRSV, PDV and their synergy, the rusty mottle group, little cherry, ACLSV, CVA and CRLV: transmission routes, what has been found in Greece, sampling and diagnosis.
The bacterium that destroyed the olive groves of the Salento: how the biofilm kills the tree by thirst, why the nymph of the vector is the only accessible target, why there is no cure, and the two resistant olive cultivars that are now the one hopeful development.
The larva eats the inside of the trunk for two or three years, and the tree fades with stunting, chlorosis and small leaves, the same picture as Phytophthora, Armillaria or a nutrient deficiency. Identification of adult, larva and egg, the multi-year cycle, why it returns to the same trees, the distinction from the leopard moth, and what pheromone traps are actually good for.
