摘要:
Compositions of natural origin for treating physiopathies and diseases caused by postharvest fruit and vegetable pathogens, and a method for their application, whereby the compositions contain as a main active principle a mixture of timol, eugenol and cinnamaldehyde and as a secondary active principle a mixture of cuminaldehyde, geraniol, vanillin, borneol, menthol, acetol, terpineol, limonene, and glycosides of the essences of mustard and jasmine, whereto an essence or extract containing salicylic acid is added or certain derivatives of the latter (esters or amides), a tensioactive that is acceptable by food standards, oligosaccharides of different natural origin and other ingredients such as chitosan, phosphorous acid (or its salts), or phytosanitary products, pesticides or synthetic antioxidants. The method of application of these compositions consists of including them in the washes or waxes usually employed in the postharvest treatment of fruit and vegetables.
摘要:
The object of the present invention is a formulation with the potential to increase the efficiency of a plant's assimilation of nutrients both in normal conditions and in conditions of nutrient deficiency. It is especially effective in the case of iron assimilation in conditions of deficiency of this micronutrient, by improving and potentiating a plant's specific response to iron deficiency, increasing the plants capacity to mobilize and assimilate the iron present in non-assimilable forms. The formulation is characterized in that is contains a compound of the formula
where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 can be hydrogen, an alkyl, aryl or phenyl residue.
摘要:
This invention relates to a new formulation activating the absorption of mineral nutrients by plants. Consequently, it has also an effect on the metabolization of these mineral compounds by the plant. These formulations that have been discovered with this property activating nutrient absorption have as main component the compounds represented by general formula I
CH3-S-CH2-CH 2 -CH(OR 1 )-COR 2 I
where R 1 is selected from the group formed by hydrogen, alkyl rests, (preferably methyl or ethyl), and aryl: while R 2 is selected from the group formed by hydroxyl, amides, alkyl rest esters (preferably methyl or ethyl), or aryl. When the rest is hydroxyl, acid salts with monovalent cations, preferably Na + and K + , polyvalent cations, preferably Cu ++ and Fe +++ , and electropositive organic compounds such as amines (e.g., ethanolamine) are also considered.
摘要:
A fertilising composition comprising an inorganic matrix insoluble in water but soluble in the organic acids released by the plant roots into the rhizosphere, wherein said matrix comprises in turn one or several double salts of phosphorus with calcium or magnesium, and one of the metals chosen from Fe, Al, Mn, Cu, Zn, B and Co, with the condition that the Al is chosen only when the other element of the double salt is Mg, and wherein the double salts are optionally chemically associated to organic compounds with chelating ability by means of metal bridges. The composition may further contain an initiating fraction formed by soluble salts of Fe, Al, Mn, Cu, Zn, B and Co, and one or several components chosen from nitrogen and potassium sources, organic matter sources, nitrification or urea hydrolysis inhibitors, phytoregulators and pesticides may optionally be incorporated thereto; a method for preparing the fertilising composition and a method for fertilising the soil are also provided.
摘要:
A new use of 2-hydroxy-4-methylthiobutanoic acid (HMTB) as an inducer, within the plant, of ethylene and polyamine synthesis, mainly putrescine, capable of regulating fruit maturation processes, both in relation to fruit abscission and in relation to color and sugar content, containing mineral elements such as phosphorous, potassium and nitrogen.

Heteromolecular metal-humic organic complexes of the type:
(A)n-(Metal)x-(B)m
where A is one or several humic complexes which may be totally or partially sulfonated or may have been treated with an amine in order to protect the carboxylic groups from interacting with polyvalent cations, and B is a non-humic complexing (organic chelating agent) compound, the biological and chemical stability whereof allows for protection of the metal and the multitoothed molecule involved in the complex against degradation phenomena, both chemical and microbiological, having the beneficial effect of humic acid, as an effective plant growth and nutrition stimulant and as a metabolic and immune system activator in animals and humans.
