Functional health-care pesticide with fertilizer capable of activating plant immunization, promote plant growth, barrier insect infection

Abstract

The invention discloses a functional healthy medical fertilizer for activating plant immunization, facilitating growth, obstructing virus transmission by insects, which essentially consists of 1-18 percent of sodium alginate, 0.5-12ppm of salicylic acid, 0.5-12ppm of lactone of zinc sulfate and 1-10 percent of brassin according to quality percentage. When applied to transplanted seedlings for root soaking and leaves surface spraying, the solution of medical combination of the invention shows remarkable biological activities: (1) being able to facilitate development of a root system and inhibiting infection to the root system from soil borne diseases, (2) obstructing the virus transmission of insect vectors, being able to replace or remarkably reduce the use of chemical insecticide on the field and presenting huge economic, environmental and social benefits, (3)inhibiting the infection of the virus, (4) activating functions of an immune system of solanaceae plants, presenting curative effects for virus diseases and securing vigorous growth of plants.

Description

technical field [0001] The invention relates to a functional health-care medicinal fertilizer, in particular to a functional health-care medicinal fertilizer for activating plant immunity, promoting growth and blocking insect transmission of toxins. Background technique [0002] At present, the current situation and development trend of commonly used plant virus disease drugs at home and abroad: there are as many as 909 kinds of plant viruses, and they are widely distributed and seriously harmful. Every common cultivated plant is damaged by one or more viruses. China has recorded that 209 kinds of vegetables (excluding varieties) are infected by 195 kinds of viruses, and every kind of vegetables has viral diseases. Plant virus diseases have become the second largest type of plant diseases after plant fungal diseases, and the annual loss caused by plant viruses in the world is about 4.0×10 10 U.S. dollars, of which the United States reaches 2.0×10 9 USD or so, losses from t...
