Olive knot disease causes the formation of raised knots or galls primarily on young branches and stems. Young olive plants are particularly non-resistant to infection . Also, harvest occurs in fall or winter when rain is likely. Krogerrecklenfort, H. Gram-negative bacteria commonly use the N-acyl homoserine lactone AHL signaling molecules. Journal of Agricultural and Food Chemistry 54 15 Always check with your certifier if products are permissible to be used in your organic production system. Not all copper compounds are approved for use in organic production; be sure to check individual products.

Wohanka, C. Alternatively, interactions between P. Vivian, S. Plant Bacteriology. Plants are always susceptible, but it is unlikely that the bacteria will cause infection naturally in distinct dry seasons.
The gammaproteobacterium Pseudomonas savastanoi belongs to the factor contributing to knot development that is controlled by PleD.
Additionally, plants contain a set of receptors that respond to microbe-associated molecular patterns to induce production of antimicrobial agents .
