UNIDAD ASOCIADA "SISTEMAS AGROFORESTALES": ESTACIÓN FITOPATOLÓXICA DO AREEIRO - MISIÓN BIOLÓGICA DE GALICIA
|Home » Services » Analysis information|
The main aim of the Estación Fitopatolóxica do Areeiro is providing a correct and rapid diagnosis to individuals, cooperatives, farmers and technicians. At present, the services available in our laboratory are:
As follows, we provide some general guidelines for the collection and transportation of plant material, soils, substrates and peat for analysis:
1.- 1. Plant samples:
It is of crucial importance to send the sample in
the best possible conditions, since the diagnosis is almost impossible when
samples arrive to the laboratory completely wilt or
Roots: Roots are collected with a good portion of soil, then they are placed inside plastic bags and introduced in a cardboard box. Seal the box for its submission.
Leaves, flowers, buds, tender branches: They must be sent without external moisture, spread in the middle of absorbent paper or newspaper sheets and protected inside plastic bags, so as they are not damaged during their transportation.
Stalks and branches: They can be submitted in the same way as leaves and flowers. If they are large, they can cut in smaller portions.
Fruits, tubercles and bulbs:They must be wrapped inside newspaper sheets to absorb their moisture and then placed inside plastic bags or cardboard boxes. Select only those samples presenting initial symptoms, thus avoiding samples presenting any damage occurring during transportation.
Seeds: inside plastic bags
Arthropods: Samples can be collected and submitted following two proceedings: together with the substrate (plant or soil) and introduced in paper boxes or bags and later inside plastic bags, or without the substrate. If the arthropod is alive, its introduction inside a recipient with a hermetic seal is advised (in case of larvae/nymphs it is advised to add a piece of plant). If it is not alive, it can be placed inside a hermetic tube. In every case, it is advised to take more than a specimen. Butterflies or moths are placed inside a piece of card folded as a pyramid. To avoid any confusion, every sample must be correctly identified with a number or a name, with its equivalent in a separate sheet.
2.- Soil samples:
Around 1 Kg of soil, peal, substrate, etc. must be collected in several points around the plant and then must be placed in a plastic bag correctly sealed.
Apart from the sample itself all relevant information must be included to facilitate their diagnosis: characteristics of pest and disease damage, its evolution in the field, as well as temperature, relative humidity and other environmental conditions occurring in the affected plantation, soil characteristics, culture practices and different chemical treatments applied.
Once this requirements are fulfilled, submit samples to:
