摘要:
The subject of the invention is new strains Pantoea agglomerans T16/8 and Pantoea allii T14/15, deposited in the Polish Collection of Microorganisms PCM at the Institute of Immunology and Experimental Therapy of the Polish Academy of Sciences named after Ludwik Hirszfeld in Wroclaw. The subject of the invention is also the use of the new strains Pantoea agglomerans T16/8 or Pantoea allii T14/15 as agents for protecting vegetable, fruit, agricultural, and ornamental plants against fungal diseases such as white rot, gray mold, alternariosis, anthracnose, brown rot, bull's eye rot, powdery mildew andblue mold, as well as bacterial diseases such as fire blight, soft rot, affecting cultivated plants, both during the growing season and during the storage of crops. Strains Pantoea agglomerans T16/8 or Pantoea allii T14/15 are applied in the form of an aqueous suspension to the plant's surface, through spraying, soaking plants or their parts under storage conditions, under cover, and in field conditions, and the cell count of the strain in the suspension is at least 107 CFU/ml.
摘要:
A titanium-containing formulation contains complexes of titanium salts with an ascorbic acid and a citric acid, a preservative agent, and water-soluble sulfates of metals absorbable by plants, and optionally additional plant nutrients, in particular nitrogen and potassium. The titanium-containing formulation is a product of titanium complexation reaction of titanyl sulfate with a mixture of ascorbic acid and citric acid in aqueous environment alkalized with magnesium hydroxide in presence of acetic acid, at a mass ratio of magnesium, calculated as MgO, to titanium amounting from 1:1 to 20:1. Furthermore, in the titanium-containing formulation a mass ratio of the ascorbic acid to the citric acid amounts from 5:1 to 3:5, a mass ratio of the ascorbic acid to titanium amounts from 7:2 to 10:1, and a mass ratio of the magnesium hydroxide, calculated as MgO, to the acetic acid, calculated as 100% of the acetic acid, amounts from 8:1 to 3:5.
