What is the BIP (or PBI in French) process ?

Prophylaxy

It is necessary to prepare the crop and its environment so as to ensure it starts in the best conditions i.e. :

• Start the crop in a clean greenhouse : a “lobby” is advised between each crop. The duration and conditions of this “lobby” depend on the layout of the greenhouse (concrete or on soil) sanitary, of the development cycle of the pests (itself in function of the temperature inside the greenhouse). If a sufficiently long “lobby space” cannot be maintained, it is necessary to undertake realise, in addition, a chemical disinfection.
• Use young plants free from diseases or pests. Each batch of plants/seedlings must be controlled on arrival so as to identify plants already infected.
• Respect some hygienic rules : disinfection cutting tools, the installations ; avoid using again left-over sowing or non disinfected pots.
• Master the climatic characteristic of the greenhouse : hygrometry, light, water availability and aeration of the substrate.
• Close the doors of the greenhouse so as to limit the entries of pests from other compartments or from outside
• Eliminate weeds in and around the green house : they can be host to a number of pests. The same applies for all plant debris.

 

Crop observations

• Working in BIP (or PBI) necessitates regular observations and a good knowledge of the crops.
• Eliminate rapidly plants with bruises as they may host diseases or pests

 

Determination of the fauna present

The person responsible for phytosanitary control in an enterprise must be able to identify all the pests and beneficial organisms. It is also necessary to know the biology of the different living organisms. In fact, the knowledge of the developmental cycle of a pest and the factors that may influence it and lead the choice of a control strategy.

Actions

• The beneficial organisms must be brought in very early, as soon as the first pests appear or preventively, as soon as the crop is planted, if the beneficial organism has the possibility to find a substitute of food or by organising a system of alternate host
• The releases are done in low quantitiesbut repeatedly.
• The application method is adapted to the type of beneficial organism (punctual releases or homogeneous dispersion on the crop).
• The choice of the beneficial organisms is done in function of the climatic conditions and of the density of the pests’ population.
• Associations of beneficial organisms are also possible (use of beneficial organisms having a complementary action : parasitism on different larval stages).
• The choice of a chemical treatment is taken when an beneficial organism does not succeed in mastering sufficiently a pest’s population. Preference will be then given to a product compatible with the beneficial organisms present in the greenhouse

 

Respect of the regulation

• Respect of the approved lists of insecticides, fungicides and herbicides compatible with the BIP (or PBI).

 

Tracability (record) of the cultural operations

• Number and surface of each greenhouse in use
• Date of planting and date of uprooting.
• Introduction of beneficial organisms (species introduced, date, quantity).
• Phytosanitary treatments (date, products used, dosage applied, problem concerned, surface treated).
• Weeding around the greenhouse (date, product used).
