Abstract

The invention discloses a method for preventing and treating the tobacco root knot nematode disease. The method comprises the first step of agricultural prevention and control, the second step of physical prevention and control and the third step of chemical prevention and control. The step of agricultural prevention and control includes the substeps that firstly, tobacco and graminaceous crop rotation is conducted for 3-5 years; secondly, plant ash and quicklime are used in the ratio of (3-4):1, 150-250 kg of the mixture is applied to each mu of field and scattered before deep ploughing and winter baking, and deep ploughing and winter baking are completed before winter to reduce overwintering eggs; thirdly, an organic fertilizer is applied, 30-50 kg of compost cake fertilizer and 150-250 kg of compost agricultural fertilizer are additionally applied to each mu of field, and then deep ploughing is conducted to improve soil fertility. A prevention means is used, and the plant ash and the quicklime are used for acidification and are combined with physical prevention and control and chemical prevention and control. The tobacco root knot nematode disease can be effectively prevented, the tobacco yield is increased, the tobacco grade is improved, and good economic benefits are obtained.

Description

technical field [0001] The invention belongs to the field of tobacco disease prevention and control, and in particular relates to a method for preventing and treating tobacco root-knot nematode disease. Background technique [0002] Tobacco, Latin scientific name: Nicotianatabacum, is an important economic crop. Tobacco is an annual herbaceous plant in the family Solanaceae, and there are about 60 species of Nicotiana. Tobacco root-knot nematode (Tobacco Root-knot nematode) is caused by root-knot nematodes invading the roots of tobacco plants. This nematode belongs to the phylum Nematodes, the class Nematodes, the order of the order, the order of the order, the order of the order, the family of the superfamily, the family of Heterodermis, and the genus of root-knot nematodes. In our country, root-knot nematode incognita is the main damage, and the pathogen belongs to the nematode door, Pleurocerus glandularia, Thyropodidae, Heterodermaidae, and Meloidogyne genus. The root...
