At the world level, a large array of pathogens (fungi, virus, insects...) can cause problems and affect reliability and quality of tobacco production. European productions, and in particular, French, do not make exception. Problems related to pathogen control are shared by all the tobacco business. They can affect tobacco from sowing, up to cigarette storage.

Generally, there is not only one method to solve a problem arising from a particular pathogen. It is mostly through a combination of several approaches that quality is ensured.

Upstream, development of these combinations, in forms compatible with production processes, requires a thorough knowledge of the implied pathogens. In these domains, the Tobacco Institute works with different research organizations (INRA, Universities), in particular for the European project VRTP Impact (Virus Resistant Transgenic Plant Impact).

Downstream, tests of application of new techniques or methods are necessary. When new methods prove to be interesting, the National Interprofessional and Technical Tobacco Association (ANITTA) takes over, and carries out tests under real conditions of growing.

Work completed more specifically by the Tobacco Institute fits between these two poles:

 
. . .
 
tests of new molecules or biological agents, and defining conditions and amounts of application, in relation with agrochemical partners,
breeding resistant varieties, development of biological or molecular tests (PCR) to detect resistance genes in plants,
a service of diagnosis, which allows cooperatives and growers to identify the cause of problems arising during cultivation,

more generally, accumulated experience is used to highlight the best combinations of techniques and to promote Integrated Pest Management.
