Microcrystalline structure with microcavities containing water and cations that can be exchanged
with other heavy metals, mycotoxins, ammonium ions that can be retained and disposed.Excellent cation exchange capacity
that limits to a minimum the losses due to
natural leaching.Moisture absorption and limiting disease, with microcrystals that form a barrier against powdery mildew, brown rot, botrytis, and reduced the insect eggs and mites which remain under the surface of the mineral or those that remain above.Silicon presence strengthens and creates an increase in leaf thickness improving the activity of the photosynthetic process Chabazite can absorb, chelate, and remove from the vegetation harmful and toxic substances.Chabazite increased the effects of the agricultural chemicals and improves the permanence of the products on the leaves.
Recent years awareness of the risks associated with chemical products for the plants protection
has led to the search for alternative techniques. New methodology of the "Particle film technology": protective barrier on the vegetation by means of various powders.
Protective film must have the basic requirements:
- Chemically inert (particles of less than 10 uM)
- Create a uniform layer that alters and hampers the insect behavior however, it should not impede gas exchange of the plant
- Must allow the transmission of radiation necessary for photosynthesis and to exclude, in some measure as ultraviolet and infrared
- Must be easily removable in pre-harvest
The plant tissues covered by this film are unrecognizable to the touch, the sight and smell of insects. Principal mode of action of chabasite is the repellency of adults with reduced activity and trophic ovoposition. Reduced the insects movement, the trophic activity and other physical activities, such as the anchor to plant.Significant effect on reducing the incidence of bacterial and fungal attacks such as Erwinia amylovora, and Venturia inaequalis.Prolongation of the effect of plant protection treatments such as copper and sulfur on leaves and fruit (about 10 days more) Moisture absorption effect that causes the germination of spores of mushrooms and intervention on the absorption of odors that can attract insects.
Plasmopara viticola Mildew
Oomycete accidentally imported from America to France in 1878 Causes downy mildew, strongly influenced by the climate cycle (rule 3 ten): Daily minimum temperature greater than 10 ° C At least 10cm long shoots with well-differentiated stomatal openings Rain of at least 10 mm Zoospores equipped with flagella move in the water and reach the openings stomatal and penetrate it, when you have a relative humidity greater of 92% and temperatures of around 13 ° C is formed white mold Necrotic leaf.Yellowing of the bunches with characteristic S shape and desiccation Partial or complete drying of the grapes with a hook shape.
Effects of protective films on plants
Studies in fruit crops have shown that photosynthesis and harvest aren’t reduced
by protective film layer Increased reflection of solar radiation with significant reduction Temperature of the leaves and solar injuries that may result in production losses First applications of the protective film for the defense of pests have been carried out in United States in 1999-2000 (Xylella of screw) Currently in America it is 70% of plants with protective films compared to 17% 2000 First successes have been achieved in the fight against the psyllid of Pero(Cacopsylla piricola) leading foliar necrosis, defoliation and production reductions. The insect develops resistance to insecticides.
Effects of protective films on plants
Significant effect on the water of the leaf, on succulence and density of leaf
Lowering the temperature of the leaf is in the case of irrigated vineyards both of non-irrigated Leaves treated with zeolite showed higher rates diurnal assimilation of carbon dioxide in the case of drought Alleviates the negative effects of drought stress.
Increase of the content (25%) of resveratrol and sugar in the vines treated with zeolitite Greater control of the attack by insects and fungi.
Effects of zeolitite on protection against powdery mildew
Trophic plant disease caused by fungi of the family of Ascomycota
Erysiphaceae the asexual stage of the cycle, in the past identified with the kind of imperfect fungi Oidium. The trophic relationship between the agents mildew to host plants is a parasitism bound The anatomical and physiological relationship that binds the pathogen host consists of austorii crossing the epidermis by penetrating into the underlying tissue. The macroscopic consequence of the general behavior of Erysiphaceae It is the formation of a felt of whitish color and a powdery appearance, on the the surface of the affected organs, due interweaving of hyphae and the issuance of a number high spore.
Radical alterations, galls are formed on gnarled sprouts and tuberosity on older roots
Root reduction.Progressive deterioration of the plant which reduces the productions.Aphid of American origin, introduced in Europe in 1850.Cycle of American lives, as overwintering eggs on branches Parthenogenetic females that bite the leaves leading to the development of galls in successive generations are born some females with long rostrum leave the leaves migrating root apparatus, where he began a series of generations radicicole.Decay of the plants up to death. Of American lives generates leaf galls.
Larvae pierce the berries in cold regions and generate pupae overwintering while.
In warmer areas originate a third generation carpophagous 1st generation is not harmful.Open the way to Botrytis and Aspergyllus carbonarius producing ochratoxin A,poisonous to humans Intervene in the 5% threshold of infested bunches Antagonists: Beauveria bassiana, Spicaria farinosa
Possible application of sustainable strategies respectful of human health and environment.Using chabasite micronized to enhance the effectiveness of conventional methods for the protection of plants.Reduction of Botrytis cinerea attacks, downy mildew, powdery mildew etc Also control of other insects (beetles and moths) and bacteria.Effect of chabasite in the stimulation of vegetative and radical part of the plants, more resistant to water stress Importance of the purity of the materials that are used to avoid phytotoxicity problems.
