Description

PHYTOSANITARY PRODUCT FOR PLANT TREATMENT

AND METHOD OF IMPLEMENTATION

The invention described below relates to a phytosanitary product for the treatment against almost all plant-eating insects parasitizing plants such as trees, vegetables, fruits, flowers and all plants in general. It relates to the process for using this product.

The product resulting from this invention is intended to fight against the phytophaqes parasites producing on the plants substances such as honeydew, waxes II also acts against the secretions, excretions which produce certain insects in order to protect their larvae II mainly dissolves the nitrogenous parts composing the protection (sclerotma) of insects and their chitin

It is very difficult, for example, to currently destroy psyllid larvae (stage 4 and 5) because there is no product effective enough to dissolve the honeydew protecting them. It is usually necessary to spray abundantly with water associated with certain products more less detergent, corrosive in an attempt to limit infestation This process has certain disadvantages for fruit producers, for example, who are forced to do a lot of repetitive treatments. II results in higher intervention costs, aggression and saturation of the products on the plant, fruit or vegetable This without forgetting the residual side of the more or less toxic phytosanitary products which can contaminate fruits, vegetables or other plants until after harvest

From this invention we propose to manufacture a new phytosanitary product that can fight effectively against almost all harmful plant-eating insects, their secretions and excretions, their eggs, larvae, honeydew and waxes, ravaging the cercaltic, arboreal, vegetable and vegetable crops. 'ornament One of the main reasons for this new product resulting from this invention is to destroy waxes, honeydew, eggs, larvae and insects (aphids, mealybugs, psyllids, louse, red spider P ULMI, white flies, grasshoppers) a context of total non-toxicity for humans, plants, animals and the environment with the capacity to be biodegradable, while avoiding destroying the phytoseid insects predators of these same harmful insects

This product in accordance with the present invention is therefore made from a molecule of DIOCTIL SULFOSUCCINATE OF SODIUM (DSS-OT 75) having the chemical designation of BIS-2-ETHYLHEXYL SULFOSUCCINATE OF SODIUM This molecule discovered in 1937 by the company Cyanamid Company , has been used in the manufacture of shampoos in the food industry, in pharmacies for laxatives It is non-toxic for humans, animals, plants and the environment, can be diluted in water to be easily sprayed on plants with the aim of eliminating parasitic phytophagous insects, their eggs, their larvae, their secretions and excretions (honeydew wax)

In addition, the non-toxic and bio-degradable DSS-OT 75 molecule has been approved in the United States by F D A and E P A (N ° 40 CFR 1801001) as well as by B G A in Germany

The molecule of DSS - OT 75 has a polar part and a non-polar part offering a complete inocuit for the metabolism of plants, fruits and vegetables, without modifying the organoleptic aspect. Furthermore, it is bio-degradable in water. the air and the earth

Here according to the standards of its manufacturer (Cyanimid Company) the developed of the molecule of DSS - OT 75

O C2 H5

H2 C - C - O - CH2 - CH (CH2) 3 - CH3

Na 03 5 C - C - O - CH2 - CH (CH2) 3 - CH3

H O C2 H5

Also according to the manufacturer Cyanamid Company the percentages by weight of the molecule DSS - OT 75 are as follows

• DSS 75%

• WATER 19%

• ETHANOL: 6%

The percentages by weight relative to the mixture of the various chemical components used in the manufacture of the prosuit resulting from the invention are as follows.

• DSS 65 4%

• ETHANOL 5.2%

• WATER 19.56%

• ALCOHOL ISOPROPILIC 9.8% (CH3 CHO H CH3)

• XYLENOL 3.5 0 04% (C8 H10 O)

• COLORANT E102-132 10 PPM

These percentages can vary by 10% more or less without modifying the conformity, the specificity of the product resulting from the invention

The water-soluble plant protection product of the present invention is manufactured and sold in the form of a mixture of DSS, ethanol, water, isopropyl alcohol, xylenol 35, supplemented by a dye. , minus the liquid diluent (water) which should serve as a vector for the spraying of a treatment This important subsequent supply of water (liquid diluent) for use during a treatment, has the advantage of making the whole mixture, product phytosanitary more thinner (water) less viscous, facilitating the misting of the whole treatment on the foliage.

The phytosanitary product in accordance with the invention can be applied to all plants (trees - shrubs - vines - vegetables - wild plants) having harmful insect pest infestations.

The treatment method consists in diluting the product according to the invention in a large amount of water and in spraying the whole mixture on the plants parasitized by the harmful insects to be destroyed.

To use the phytosanitary product manufactured in accordance with the invention, it is necessary to mix in a very homogeneous manner from 1 to 2 liters of product (depending on the size of the foliage) in 1000 liters of water (diluent) having a pH lower than 7. This volume of 1000 liters of water with HA, for a treatment, can be increased or decreased according to each type of culture, and will have to be sprayed on all the foliage, of the plant. This is to obtain perfect wetting over the entire infestation.

The principle of action on harmful insects, their eggs, larvae, honeydew, waxes, product azootées contained in their natural protections, in a mechanical way, exposing its same phytophaqes insects, eggs, larvae, waxes and honeydew to action of UV rays from the sun which destroy them permanently. Hence the importance of a perfect misting which will come into contact with all the infestation.

Several treatments can be carried out at intervals of at least three weeks, depending on the controlled degree of infestations, while respecting a standardized tolerance threshold for the quantitative occupation of insects to be destroyed on the plant.

Furthermore, the product according to the invention, sparing the predators (phytosids) of these harmful insects, allows these same predators to complete or contain the infestation within a tolerable occupancy threshold.

The product resulting from the invention can therefore be used very effectively, for example in orchards, on fruit trees.

The following example explains and demonstrates the effectiveness of the product. The treatment has been applied and demonstrates the effectiveness of the product. The treatment was applied in an orchard of 1 ha of apple trees (age 8 years) 2 months before the harvest, with a large infestation of red spider P.ULMI. A preliminary count of the population of these insects gave a leaf occupancy rate of more than 80% with an average of thirty red spiders per leaf, having a whole population of eggs and larvae in full growth.

It was also noted the presence of many phytoseldes predators of these red spiders P ULMI In case of high temperature specific to the season, these predators (typhlodromes) cannot by themselves stop the explosion of the growth of the infestation of spiders red

For the preparation of the treatment, a mixture of 15 liters of product in accordance with the invention was mixed with 1000 liters of water, the pH of which was lower than 7

The treatment was carried out by misting the water (thinner) plus product mixture, on each tree so as to thoroughly wet the foliage, the trunk, the antlers in its entirety This treatment was waxed early in the morning before the appearance of the high temperature of the day to avoid evaporation of the mist, during the treatment A count made 4 days after the treatment in this same plot treated with the product resulting from the invention made it possible to verify that 96% of the eggs and larvae were destroyed along with 96% of the adult red spiders

On the other hand, it was noted after this same treatment the presence of predatory insects (typhlodromes) certainly in less quantity What is normal because the population of harmful insects, red spiders P ULMI strongly regressed at the same time

A control of this same orchard carried out 3 weeks after this treatment, made it possible to note the normal appearance of the orchard with an infestation of 2 red spiders P ULMI per leaf with an occupancy rate of 5% of the foliage The infestation had therefore been reduced to an acceptable standard tolerance level
