Italian Association for Organic Agriculture - Italy

Initiative partner

AIAB is an association of producers, engineers and citizen-consumers. It is the networking of the organic movement and represents primarily the interests of organic producers, through the promotion of organic agriculture as a sustainable development model, based on the principles of conservation and exploitation of resources, the environment, animal welfare and the health of the consumer. Organic farming is, in fact, a model of development for the Italian countryside alternative to '"industrial agriculture", capable of addressing the ecological sense in the behavior of market participants and general public and, in particular, an approach to the method of production and consumption. The interests of organic producers affect the interests of citizen-consumers and enhance the role and function of the technicians that specialize in organic farming.

Initiative partner

CRA PAV deals with the protection of agricultural and forestry plants by biotic agents (bacteria, fungi, viruses, viroids, phytoplasmas, etc..) and abiotic stress (physiological disorders, adverse climatic conditions). Studies are carried out on the interaction between plants and pathogens, on the epidemiology and characterization of populations of pathogenic organisms using traditional methods and molecular biology to control diseases. Researches focus on the genetic sources of resistance to pests and tolerance, to be applied to the development of varieties / lines resistant through the use of conventional methods and biotechnology. CRA PAV investigates crop protection methods in the context of conventional, integrated and organic practices. Attention is given to methods useful in the diagnosis of disease prevention, to techniques and methods of treatment which may minimize the occurrence of pesticide residues in food and the environment. Applied projects aim at remediation techniques for the production of propagation material certified free of pathogens.

The project aims at the development of innovative technologies for biological control of pests and soil pathogens (fungi and nematodes) of Mediterranean vegetable crops (carrot, potato and tomato in Puglia, Lazio and Sicily) and forest areas in the Apennines (walnut and chestnut in Tuscan-Emilian Apennines). Formulations are developed based on micro-organisms of the rhizosphere. The parasites are: Heterodera carotae, Meloidogyne and Globodera spp. for nematodes and Pyrenochaeta lycopersici, agent of tomato and vegetables corky root rot; Phytophthora and Armillaria spp. on trees. The antagonists considered wre: nematophagus bacteria and fungi, predatory nematodes (Diploasteridae); bacteria and Trichoderma spp. against soil-borne fungi; fungi and nematodes myco- or bacteriophagous against pathogenic fungi (Phytophthora, Armillaria). At the molecular characterization follows the production of formulates, with essays in the field of molecular probes and descriptive models.

Main technologies for soil-borne pathogens and pests like fungi or nematodes relied on
soil fumigants. We propose innovative organic approaches respectful of the environment,
as alternative to chemicals. At the end of the trial we have available: 1) new tools for plant
protection based on microorganisms; 2) data on the biology, sequencing and molecular
probes for monitoring of biological antagonists; 3) collections of micro-organisms; 4)
experimental data from biological control assays on nematodes and fungi; 5) prototype
formulations; 6) molecular probes and non-linear predictive or descriptive models.

Model describing the effect of the fungus Pochonia chlamydosporia against p Effect of the parameter sigma on parasitism and biocontrol efficacy. The parameter controls the fungus saprotrophic growth. Increasing the fungus density in soil as a saprotroph also increases nematode parasitism

The Italian Ministry of Agricultural and Forestry Policies supports research on organic farming and
food safety through projects based on the National Program for Research in Organic Agriculture.
Project BIOMED reflects the mentioned program, starting from principles such as
multifunctionality of agriculture, sustainability, reduced use of fossil fuels, reuse of organic waste
or secondary materials, improvement of cultivation techniques and protection of plant and natural
antagonists diversity. The research focuses on new techniques to produce scientific and technical
data, integrating lab and field assays. The connection between research and production includes
knowledge for biopesticides efficacy and safety, product quality, organic biomass recycling and
respect for the environment. BIOMED goal is the substitution of high environmental impact
technologies (fumigations), by others based on knowledge about the organisms and
environments involved.

Eggs of a plant parasitic nematode parasitized by a fungus Nematophagous fungi like Pochonia or Lecanicillium spp. are capable to digest the eggs of many invertebrate pests, including insects or nematodes parasitizing plants.

Scientific benefits include new knowledge on the biology and epidemiology of soil pests and pathogens, of
their antagonists and on biological control in different Italian environments. Benefits concern the availability,
for producers and industries active in the field of biopesticides, of prototype formulations for biological
protection of carrot, potato, tomato, walnut and chestnut, and the technology transfer to industries. They also
include the development of organic technologies for protection of chestnut and walnut with amendments and
their diffusion, due to the impact of these crops on the economy of rural areas with low agricultural
intensification. Main social impact is linked to the development of organic farming and food productions.
Results dissemination is a second social impact, promoting biological technologies between farmers and
producers and a constructive exchange among researchers involved in different research lines and operators
or users (technicians, farmers).

Field and greenhouse trials in Sicily Experimental assays for control of root-knot nematodes with organic products

Dealing with living organisms to produce a product offering a standard service for crop protection does
not always warrant an efficacy or stability of results. This is the case of predatory nematodes, that in
spite of their direct impact on a target nematode prey, appear difficult to rear in vitro for practical
exploitation, due to a susceptibility to their own pathogens and antagonists. Also the isolates of fungi or
bacteria often show differences as concerns their suitability as basic ingredients of biopesticides, due to
variable genetic effects or compatibility, and require in vitro testings for selection, that are time
consuming.

Predatory nematode Koernersia sp. was tested for biocontrol applications. The nematode, however, is subject to its own bacterial antagonists affecting its production in vitro

Two fungi, Pochonia chlamydosporia and Trichoderma virens, with related species, are close to the
step of becoming the basic ingredients of industrial biopesticides or ammendants, due to their positive
impacts on protection of vegetables in Mediterranean horticulture. Pochonia furthermore is not only a
nematode killer, but also a plant growth promoter, due to the induction of resistance gene in plants that
it can colonize as an endophyte. Organic approaches to pest and disease management like this one
protect soil microbial biodiversity and save energy, relying on living rganisms. Similarly, the
management of tree crops like chestnut and walnut with organic matters, including chicken manure,
showed a positive impact for management of ink disease and other fungal based pathologies for which
no simple, cost effective management tools were previously available. It also extends and completes
the lifecycle of organic manure, offering a safe method for its recycling.

There are two type of fallouts: the first is mainly scientific, related to the publications describing the
new knowledge produced, and to the information acquired, which is now integrated in further scientific
initiatives. The second fallout is technical, promoting new approaches for sustainable pest and
disease management, in the field. First fallouts will be durable in time given they are published in
international journals and are also the basis for new ongoing projects or proposals, dealing with
Pochonia or Trichoderma. The second fallout is expected to increase the demand of safer organic
tools for pest and disease management, possibily traducing the experience gained in field trials in new biopesticide industrial products.
