Abstract

The invention discloses a prevention and control medicament for tobacco black shank and a use method thereof. The prevention and control agent comprises an agent A and an agent B. The agent A comprises: 46% of a copper hydroxide aqueous solution 1000-fold solution, 2% of a kasugamycin aqueous solution 500-fold solution and 20% of a thiediazole ketone emulsion 300-fold solution; and the agent B comprises: 6.25% of a fluopicolide 2500-fold solution, 62.5% of a propamocarb hydrochloride 2500-fold solution, 22% of a penflufen 2500-fold solution and 41.7% of a fluopicolide 10000-fold solution. According to the method, tobacco seedlings are treated through the medicament, rhizomes of the tobacco seedlings are not subjected to medicament treatment, root irrigation treatment is conducted after the tobacco seedlings are transplanted, the prevention and treatment effect on tobacco black shank is more thorough, and tobacco growth is not affected. According to the invention, germs carried by the tobacco seedlings and in the soil can be effectively and thoroughly eradicated, a soil conditioner is applied before tobacco seedling transplanting to improve the soil, control the soil germs and improve the actual application value of the soil, so that the tobacco black shank can be effectively and thoroughly eradicated, the dosage is small, the cost is low, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a preventive and control agent for tobacco black shank and its application method. Background technique [0002] Tobacco black shank, also known as tobacco black root and black stem madness, is an important soil-borne fungal disease that occurs on tobacco caused by Phytophthora nicotiana infection. It mainly infects the roots and stem bases of tobacco, forming black sunken spots on it, so it is called "black shank". The seedbed stage generally occurs less, and mainly damages the tobacco plants in the field stage. [0003] Tobacco black shank mainly infects the roots and stem bases of tobacco, and generally occurs less frequently in the seedbed stage, and mainly damages tobacco plants in the field stage. Symptoms vary greatly depending on the growth stage of the tobacco plant and the climatic conditions. However, the current methods for preventing and treating tobacco ...
