DESCRIZIONE DESCRIPTION

Annessa a domanda di brevetto per INVENZIONE INDUSTRIALE avente per titolo: Attached to a patent application for INDUSTRIAL INVENTION entitled:

"USO DI ARGILLE ACIDE PER IL TRATTAMENTO DI COLTURE CONTRO L’ATTACCO DI INSETTI FITOFAGI" "USE OF ACID CLAYS FOR THE TREATMENT OF CROPS AGAINST THE ATTACK OF PHYTOPHAGUS INSECTS"

La presente invenzione riguarda l'uso di argille acide per il trattamento di colture contro l'attacco di insetti fitofagi. The present invention relates to the use of acid clays for the treatment of crops against the attack of phytophagous insects.

Nel ultimi decenni si è osservato un forte incremento della cosiddetta "agricoltura biologica", la guale richiede, tra l'altro, di attuare trattamenti fitoterapici sulle colture che utilizzino prodotti di origine naturale che siano esenti da problemi di tossicità sia in fase di applicazione sia per il consumatore finale. In recent decades there has been a strong increase in the so-called "organic agriculture", which requires, among other things, to implement phytotherapeutic treatments on crops that use products of natural origin that are free from toxicity problems both in the application phase and for the final consumer.

In tale ambito, è noto l'impiego, soprattutto in frutticoltura e viticoltura, di argille acide per aumentare la resistenza di diverse specie vegetali all'attacco da parte di funghi e batteri patogeni. Tali argille acide sono in genere costituite principalmente da allume di rocca, eventualmente in miscela con bentonite, e sono disponibili sul mercato sotto diversi marchi, ad esempio Mycosin® ed Ulmasud® della società Biofa AG (Germania). In this context, the use, especially in fruit growing and viticulture, of acid clays is known to increase the resistance of various plant species to attack by pathogenic fungi and bacteria. These acid clays generally consist mainly of rock alum, possibly mixed with bentonite, and are available on the market under various brands, for example Mycosin® and Ulmasud® of the company Biofa AG (Germany).

E' noto che molte coltivazioni, in particolare in frutticoltura e/o orticoltura, possono subire l'attacco di diversi insetti fitofagi, i guali, nutrendosi delle porzioni esterne della pianta (in particolare frutti, foglie e/o germogli) e/o dei liguidi interni (linfa), ne minano lo sviluppo vegetativo e, nei casi più gravi, possono causarne la morte. Il trattamento contro tale tipologia di attacchi prevede solitamente l'impiego di sostanze insetticide di origine sintetica, aventi in genere elevata tossicità e che guindi possono essere applicate sulle colture solo secondo serveri protocolli per evitare effetti nocivi per 1'applicatore, l'ambiente ed il consumatore finale. It is known that many crops, in particular fruit and / or horticulture, can be attacked by various phytophagous insects, the guali, feeding on the external portions of the plant (in particular fruits, leaves and / or shoots) and / or internal liguides (lymph), undermine its vegetative development and, in severe cases, can cause its death. The treatment against this type of attacks usually involves the use of insecticidal substances of synthetic origin, generally having high toxicity and which can therefore be applied on crops only according to strict protocols to avoid harmful effects for the applicator, the environment and the final consumer.

La Richiedente ha ora trovato che argille acide come gui di seguito definite possono essere utilizzate per il trattamento di colture contro l'attacco di insetti fitofagi, così da ottenere l'eliminazione sostanzialmente completa di tali insetti senza utilizzare prodotti chimici di sintesi. The Applicant has now found that acid clays as defined below can be used for the treatment of crops against the attack of phytophagous insects, so as to obtain the substantially complete elimination of such insects without using synthetic chemicals.

Secondo un primo aspetto, la presente invenzione riguarda pertanto l'uso di un'argilla acida per il trattamento di colture contro l'attacco di insetti fitofagi . According to a first aspect, the present invention therefore relates to the use of an acid clay for the treatment of crops against the attack of phytophagous insects.

Preferibilmente, l'argilla acida adatta agli scopi della presente invenzione è un sale, in particolare silicato o solfato, di alluminio, eventualmente in forma di sale doppio con almeno un altro metallo, in particolare ferro, metalli alcalini (ad esempio potassio) , metalli alcalino-terrosi (ad esempio magnesio) . Preferably, the acid clay suitable for the purposes of the present invention is a salt, in particular silicate or sulphate, of aluminum, optionally in the form of a double salt with at least one other metal, in particular iron, alkali metals (for example potassium), metals alkaline earth (e.g. magnesium).

In particolare, l'argilla acida è preferibilmente un solfato idrato di alluminio e potassio, in particolare allume di rocca (vale a dire solfato doppio di alluminio e potassio dodecaidrato), eventualmente in miscela con almeno un fillosilicato, ad esempio bentonite e/o montmorillonite. In particular, the acid clay is preferably a hydrated aluminum and potassium sulfate, in particular rock alum (i.e. double aluminum sulfate and potassium dodecahydrate), optionally in mixture with at least one phyllosilicate, for example bentonite and / or montmorillonite .

Le argille acide impiegabili secondo la presente invenzione vengono classificate come "polvere di pietra o di roccia" in accordo con il Decreto del Ministero della Salute italiano (SACO-AOO-SACO Registro Ufficiale 000 44 31 del 18 marzo 2009). The acid clays that can be used according to the present invention are classified as "stone or rock dust" in accordance with the Decree of the Italian Ministry of Health (SACO-AOO-SACO Official Register 000 44 31 of 18 March 2009).

L'argilla acida può essere applicata, in accordo con la presente invenzione, in forma di polvere bagnabile oppure in forma di polvere secca. Nel caso di applicazione come polvere bagnabile, l'argilla acida può essere preferibilmente miscelata con prodotti adesivanti e/o bagnanti, ad esempio glicerina. The acid clay can be applied, according to the present invention, in the form of a wettable powder or in the form of a dry powder. In the case of application as a wettable powder, the acid clay can preferably be mixed with adhesive and / or wetting products, for example glycerin.

Il trattamento in accordo con la presente invenzione viene preferibilmente realizzato alla ripresa vegetativa della pianta e successivamente ad intervalli regolari (ad esempio con cadenza settimanale). L'argilla acida può essere applicata in guantità variabili principalmente in funzione dello specifico insetto responsabile dell'infestazione, del tipo di coltura e delle condizioni ambientali. Preferibilmente l'argilla acida viene applicata in una guantità da 1 a 30 kg/ettaro, preferibilmente da 5 a 15 kg/ettaro The treatment in accordance with the present invention is preferably carried out at the vegetative restart of the plant and subsequently at regular intervals (for example on a weekly basis). The acid clay can be applied in varying degrees, mainly according to the specific insect responsible for the infestation, the type of crop and the environmental conditions. Preferably the acid clay is applied in a glove from 1 to 30 kg / hectare, preferably from 5 to 15 kg / hectare

L'uso di un'argilla acida in accordo con la presente invenzione si è dimostrato particolarmente efficace contro i seguenti insetti fitofagi: Psilla, Cecidomia, Carpocapsa, Fillominatori (in particolare Lithocollete e Cemiostoma) , Afidi, Litocollete, Cidia, Piralide del Mais, Tuta Absoluta, Dorifora della Patata, Mosca dell'Olivo. The use of an acid clay in accordance with the present invention has proved particularly effective against the following phytophagous insects: Psylla, Cecidomia, Carpocapsa, Phyllominators (in particular Lithocollete and Cemiostoma), Aphids, Litocollete, Cidia, Corn borer, Tuta Absoluta, Colorado potato beetle, Olive fly.

Più in particolare, un trattamento con argilla acida secondo la presente invenzione può essere applicato : More specifically, an acid clay treatment according to the present invention can be applied:

sul Pero, contro: Psilla, Cemiostoma, Carpocapsa, Cecidomia; on the Pear, against: Psylla, Cemiostoma, Carpocapsa, Cecidomia;

sul Melo, contro: Afidi, Litocollete, Carpocapsa, Cecidomia; on the Apple tree, against: Aphids, Litocollete, Carpocapsa, Cecidomia;

sulle Drupacee, contro: Cidia, Afidi; on Drupaceae, against: Cidia, Aphids;

su colture industriali, contro: Piralide del Mais; on industrial crops, against: Corn borer;

sul Pomodoro, contro: Tuta Absoluta; on the Tomato, against: Tuta Absoluta;

sulla Patata, contro: Dorifora della Patata; on the Potato, against: Colorado potato beetle;

sull'Olivo, contro: Mosca dell'Olivo. sull'Olivo, against: Mosca dell'Olivo.

La Richiedente ha in particolare effettuato una sperimentazione su grandi superfici del trattamento con argilla acida, iniziando alla ripresa vegetativa e con interventi successivi a cadenza settimanale. In tal modo si è realizzata una copertura costante delle vegetazione ed i vari parassiti hanno trovato questa copertura già in fase di volo degli adulti. Per i trattamenti è stata impiegata una dispersione acquosa contenente 1 kg di argilla acida per 100 1 di acqua, la quale è stata distribuita sulla coltura tramite un "atomizzatore" azionato da trattore. La quantità di prodotto applicato è stata variata da 500 l/ettaro nei primi trattamenti, fino ad arrivare a 1000 l/ettaro in post-fioritura e 1200-1500 l/ettaro nel periodo di pieno sviluppo vegetativo . In particular, the Applicant has carried out an experimentation on large surfaces of the treatment with acid clay, starting at the vegetative restart and with subsequent interventions on a weekly basis. In this way a constant cover of the vegetation was achieved and the various parasites found this cover already in the flight phase of the adults. An aqueous dispersion containing 1 kg of acid clay per 100 1 of water was used for the treatments, which was distributed over the crop by means of a tractor-driven "atomizer". The quantity of product applied was varied from 500 l / hectare in the first treatments, up to 1000 l / hectare in post-flowering and 1200-1500 l / hectare in the period of full vegetative development.

Grazie a tale sperimentazione sul campo la Richiedente ha constatato che l'argilla acida svolge principalmente le seguenti azioni: Thanks to this field experimentation, the Applicant has found that the acid clay mainly performs the following actions:

- effetto repellente sugli insetti adulti, si è infatti notata una riduzione del 80-90% di adulti di Psilla del Pero, Carpocapsa e Cemiostoma e del 40-50% di Cecidomia, rispetto ad analogo trattamento con un Abamectina, un noto agente chimico utilizzato in agricoltura contro l'attacco di insetti fitofagi; - repellent effect on adult insects, a reduction of 80-90% of adults of Psilla del Pero, Carpocapsa and Cemiostoma and of 40-50% of Cecidomia was noted, compared to a similar treatment with an Abamectin, a well-known chemical agent used in agriculture against the attack of phytophagous insects;

effetto sulle uova deposte dagli insetti, grazie alle proprietà igroscopiche dell'argilla acida. effect on the eggs laid by insects, thanks to the hygroscopic properties of the acid clay.

Non si è invece osservata alcuna attività sui neanidi e sulle larve negli stadi di sviluppo successivi. On the other hand, no activity was observed on the nymphs and on the larvae in the later stages of development.
