Problems solved by technology

Traditional chemical control methods have the characteristics of less dosage and quick results. However, during the use of chemical pesticides, they have had serious negative impacts on humans and the ecological environment, not only causing excessive residues of harmful substances, destroying soil ecology, but also causing A series of problems such as human and animal poisoning and increased resistance of bacteria
Although the use of microbial control overcomes the above-mentioned disadvantages of chemical control, and research and practice have proved that it has a certain control effect on tobacco soil-borne diseases, the effect of microbial control is generally slow, and the effective active ingredients are relatively complex, which is easily affected by environmental factors. Constraints and interference

Abstract

The invention provides a mixture for controlling soil-borne diseases of tobaccos, and a using method of the mixture. The mixture mainly contains the following components: 5-15 parts of rhodiola root extract, 10-20 parts of marigold root extract, 15-35 parts of coptidis rhizome root extract and 50 parts of 95% alcohol. The using method of the mixture comprises the following steps: (1) before the tobaccos are sown, preparing the mixture and water into a solution according to the ratio of 1: 10, evenly spraying the solution to a seedling substrate, wherein 0.1-0.15L of solution is sprayed to every kilogram of substrate, and evenly mixing; after that, normally sowing, and transplanting into a big field after tobacco seedlings grow up to a standard; (2) when the tobaccos are transplanted into the big field, preparing the mixture and water into a solution according to the ratio of 1: (400-600), and filling the solution into seedling holes used for transplanting the tobacco seedlings, wherein each seedling hole is filled with 40-60ml of solution. The mixture has the characteristics of being wide in sterilization range, lasting in effect, non-toxic, safe and the like; after the mixture is adopted, the occurrence rate of the soil-borne diseases of the tobaccos is obviously reduced, and the quality of the tobaccos can be improved.

Description

technical field [0001] The invention belongs to the technical field of biological control of plant diseases, and in particular relates to a mixture used for preventing and controlling tobacco soil-borne diseases and a use method thereof. Background technique [0002] Tobacco is one of the important economic crops in my country, and it is also one of the crops most seriously damaged by diseases. Among the many tobacco diseases, the losses caused by soil-borne diseases are the most serious. Tobacco soil-borne diseases mainly include bacterial wilt, black shank, root black rot, etc. Tobacco bacterial wilt is a bacterial soil-borne disease caused by the parasitism of Ralstonia solanacearum. Tube bundle diseases; tobacco black shank and root black rot are fungal diseases caused by Phytophtora parasitica var.nicotianae Tucker and Thielaviopsis basicola respectively. On average, only tobacco black shank The economic losses caused by the disease amounted to more than 100 million y...
