preparation example Construction

[0034] The present invention also provides a method for preparing the above-mentioned amino-oligosaccharin-containing composition, the process flow of which is as follows: figure 1 shown. The method comprises the steps of:

[0035] S1: Weigh each component according to the above formula of amino-oligosaccharin-containing composition;

[0036] S2: adding an organic acid and a surfactant into a solvent for dissolving to obtain a mixture I;

[0037] S3: adding the hydroxyadenine and phytonutrient element compounds into the filler to obtain mixture II;

[0038] S4: Mix the mixed solution I, the mixed solution II, and the amino-oligosaccharin to obtain the amino-oligosaccharin-containing composition.

[0039] Specifically, in step S1 of the above-mentioned preparation method of the amino-oligosaccharin composition, the hydroxyadenine, amino-oligosaccharin, organic acid, plant nutrient element compound, solvent, surfactant, and diluent, etc. The proportions and types of have bee...

Abstract

The invention provides an amino-oligosaccharin composition and its preparation method and application. Based on 100% of the total mass of the amino-oligosaccharin composition, it includes the following formula components in mass percentage: hydroxyene adenine 0.0001~ 0.005%, amino oligosaccharin 0.1-1%, organic acid 1-25%, phytonutrient compound 2-15%, solvent 5-30%, surfactant 3-8%, filler 21-89%. The synergistic effect of the amino-oligosaccharin-containing composition of the present invention has a good control effect on plant virus diseases, and has broad-spectrum anti-plant virus properties. Compared with a single agent of amino-oligosaccharin, the control effect on plant virus diseases is improved. 30-100%. The amino oligosaccharin composition has no residue after acting on plants, and is environmentally friendly and safe. The preparation method has simple process, low cost, safety and environmental protection, and is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to an amino-oligosaccharin composition and application thereof. Background technique [0002] Plant viruses are an important cause of yield decline and quality deterioration of crops such as grain, oilseeds, vegetables, fruit trees, and flowers. The annual crop loss caused by plant viruses in the world is about 20 billion US dollars. Since the discovery of the first plant virus, tobacco mosaic virus, in 1892, more than 900 species of plant viruses have been discovered in the world. Plant viruses can cause changes in plant cells and tissue structures to cause yellowing, chlorosis, necrosis or dead spots, etc., and can also cause plant dwarfing, corkerization, leaf curling and deformity. Plant viruses can be transmitted through various routes, such as insects (leafhoppers, planthoppers, aphids, etc.) or mites, diseased leaf sap, nematodes in the soil, fungi, seeds, pollen, seedl...
