Abstract

Product comprising formic acid (27%), sodium hydroxide (38%) and sodium copper ion (NaCu+) (35%), for treating the contamination of the olive drupes by fly known as Dacus oleae, is claimed.

Description

/ The chemical design of this product, was established, after multiple field experiments, to treat according to four protocols, the damage observed on the drupe of the olive tree by an insect (fly û dyptère dacus oléa). 1 ° protocol: preventive treatment 2 ° protocol: curative treatment of infestation 3 ° protocol: treatment of soil remediation contaminated 4 ° protocol: prevention of possible contamination The insect - dyptère dacus olea - white fly yellowish first during the end of flowering period (April to June) these infestation criteria are subject to weather conditions. In the first generation, the insect pricks the fruit at the beginning of training (barely knotted), and deposits its eggs. In the larval stage there is little evidence of furrows in the pulp into the nucleus. The larva pupates and then takes off and renews the screw cycle and infestation of the drupe. Three cycles of generation were observed during the ripening period of the olive. The contamination of the fruit is made by the observation of one or more bridge stings. The development of the fruit is atrophied, during the following infestations the fruit becomes black, dries out and most often falls from the tree. The damage is considerable because even the olives remaining on the tree are unfit for consumption as are table olives that are stung and dried or olives for the production of oil because this oil will have a rate of excessive acidity. ~ FN L96IE / LI- The harvest can be lost to more than 90%; But it can also compromise other crops because the contaminated fruit falling at the foot of the tree also infects the soil and resumes the life cycle of the insect in its larval form. The chemical formula of this treatment is designed with completely biodegradable and environmentally friendly phytosanitary products as well as the taste and oleic quality of the olive. 4o CHEMICAL FORMULA OF THE DRY PRODUCT: CH.zOz + Na OH + Na Cu + 27% + 38% + 35% Treatments and treatment period: the meteorological conditions are to be taken into account for the different periods. The treatment takes place in four protocols. -2n - Preventive protocol: dry product 20% + 11.2 0 80% Treatment period from April to June: the spray of the product obtained after dilution will take the form of aerosol on the tree, the undersides of the leaves and the ground. - Curative protocol: dry product 30% + H2O 70% 25 Treatment period July to August: the spray of the product obtained after dilution will be in covering form on the top and the bottom of the leaves, the trunk and the soil. Sanitation protocol: dry product 25% + H2O 75% P3.1 Period of treatment mid-October - before harvest: the spray of the diluted product will be done in aerosol form on the tree. JEC \) And 9EJEic $ Supplementary sanitation protocol: dry product 30% + H O70% Treatment period January: the spray of the diluted product will be done in a covering form on the trunk and the soil. 3

Claims (4)

1) The chemical formula of this treatment product of the contamination of the drupe of the olive tree by the dyptère known under the name: DACUS OLEA. CIE O4 + Na + Na + Cu + 27% + 38% + 35% 2) Claim characterized in that the chemical formula of this treatment is composed of fully biodegradable and environmentally friendly products. 3) Claim characterized in that the chemical formula of this treatment has been carefully elaborated so as not to destroy the taste or oleic qualities of the olive. 4) Claim characterized in that the chemical formula gives a treatment whose effectiveness, after various experiments, has proved to be more than 90%, even in case of massive infestation.
