Embodiment 1

[0042] A control method for tobacco bacterial wilt, comprising the following steps:

[0043] 1. Soil ecological management:

[0044] (1) Apply Diflafe tobacco fertilizer, the amount used per mu is 200ml, the specific usage method of Diflafe tobacco fertilizer is to mix 15L of Diflafe tobacco fertilizer with water for every 200ml of Diflafe tobacco fertilizer, and mix the Diflafe tobacco fertilizer with water evenly Spray and surface.

[0045] (2) Apply Wo Yiduo, the dosage per mu is HYT-A 170ml, HYT-B 350ml and HYT-C120g, and use it 2-4 times throughout the growth period; add HYT-A170ml and HYT-B350ml to 15 liters of water and mix Stir well, put it at room temperature for 2 days, add HYT-C120g, let it stand for another day, add water to 250 kg, stir well and then water the roots.

[0046] 2. Biological control:

[0047] In the early stage of the disease, the roots were irrigated with 2000 times of 40% agricultural streptomycin wettable powder, once every 7-10 days, 2-3 times ...

Embodiment 2

[0058] Substantially the same as Example 1, the difference is that 300ml of Difulai tobacco fertilizer is used in every mu of land,

[0059] The dosage of Woyiduo per mu is 150ml of HYT-A, 300ml of HYT-B and 100g of HYT-C.

[0060] The incidence of tobacco bacterial wilt disease in the tobacco field using the control method of this embodiment has been reduced by more than 80% compared with the control method of the comparative example, the quality and yield of tobacco leaves have been greatly improved compared with the comparative example, and the yield of tobacco leaves has increased by more than 35%.

Embodiment 3

[0062] Substantially the same as Example 1, the difference is that every mu land uses 400ml of Difulai tobacco fertilizer,

[0063] The dosage of Woyiduo per mu is 200ml of HYT-A, 250ml of HYT-B and 80g of HYT-C.

[0064] The incidence of tobacco bacterial wilt disease in the tobacco field using the control method of this embodiment has been reduced by more than 70% compared with the control method of the comparative example, the quality and yield of tobacco leaves have been greatly improved compared with the comparative example, and the yield of tobacco leaves has increased by more than 30%.

Abstract

The invention relates to a prevention and control method for tobacco bacterial wilt. The prevention and control method comprises the following steps: firstly, soil ecological management: (1) applying a Difulai tobacco fertilizer, and (2) applying HYT(High Yield Technology); secondly, biological prevention and control: (1) using a solution formed by diluting 40% agricultural streptomycin wettable powder by 200 times for root irrigation in the initial period of disease attack once per 7-10 days, and continuously carrying out root irrigation for 2-3 times; thirdly, agricultural prevention and control: (1) selecting high-quality resistance variety, (2) implementing crop rotation, (3) selecting loosened well-drained soil for planting tobacco, and draining accumulated water in time, (4) using nitrate nitrogen in a nitrogenous fertilizer, and (5) removing diseased or infected plants in time, and using lime for performing disinfection treatment on diseased holes; and fourthly, physical prevention and control: (1) removing heavily diseased plants or plant debris in time, and destroying by melting or burning in a concentrated manner. The method adopts the measures of agricultural control, soil ecological management, biological prevention and control, physical prevention and control, chemical prevention and control and the like, so that the incident rate of the tobacco bacterial wilt is greatly reduced, the effect is good, and the yield and quality of tobacco are improved.

Description

technical field [0001] The invention relates to a method for preventing and treating tobacco bacterial wilt, and belongs to the technical field of plant protection. Background technique [0002] Tobacco, Latin scientific name: Nicotianatabacum. Tobacco is an important economic crop. Tobacco is an annual herbaceous plant in the family Solanaceae, and there are about 60 species of Nicotiana. Tobacco bacterial wilt (Tobacco Granuville wilt) is an important disease of tobacco in tropical and subtropical regions. The disease was first discovered in Granville, North Carolina (Granville, county name) in the United States in 1880, so it was widely known as Granuville at that time. Wilt wilt and tobacco bacterial wilt are caused by Pseudomonas solanacearum Smith, which mainly survives the winter on soil and diseased residues, relying on rainwater, irrigation and drainage, diseased soil, diseased seedlings, human storage, and production Spread by tools and insects. Plots heavily i...
