Problems solved by technology

[0005] The above methods 3 and 4 cannot fundamentally solve the problem. The conventional pesticides used in method 2 have poor control effects on sugarcane red rot, and cannot guarantee that sugarcane will not be infected again. Adding more or indiscriminately adding other chemicals when using medicines will not only greatly increase the cost of using medicines, but also cause serious loss of pesticides, and will also cause pollution to the environment, which will affect people's physical and mental health.
At present, there is no effective control method for red rot in China. In the prevention and treatment of sugarcane red rot, how to effectively prevent the occurrence of sugarcane red rot and reduce the use of chemical pesticides has been a subject of continuous research.

Embodiment 1

[0028] Implementation location: Ertang Town, Wuxuan County, Laibin City, Guangxi

[0029] Implementation time: March 26, 2013

[0030] Implementation area: 5 mu

Embodiment approach

[0031] The implementation method includes the following three aspects:

[0032] (1) Soil disinfection: Choose a sunny day with high temperature and good light to level the soil and irrigate it to keep the relative humidity of the soil at 60% to 85%. After that, the soil is deeply plowed once to make the lime nitrogen particles fully contact with the soil, cover the stuffy soil with a transparent film for 10 days, then remove the film for ventilation, plow the soil and prepare the site, and let it dry for more than 10 days before planting;

[0033] (2) Seed stem treatment:

[0034]

[0035] (3) Spraying of liquid medicine: After planting the sugarcane seeds obtained from the above (2) seed stem treatment: treatment 1-treatment 5, when the sugarcane is not diseased or the disease shows initial symptoms, use 150 times of botanical medicine and 0.36% bitter The 1000 times solution of ginseng base is mixed according to the weight ratio of 2:1 to prevent and control the drug sol...

Embodiment 2

[0041] Implementation location: Siling Township, Wuxuan County, Laibin City, Guangxi

[0042] Implementation time: April 1, 2013

[0043] Implementation area: 5 mu

[0044] The implementation method includes the following three aspects:

[0045] (1) Soil disinfection: Choose a sunny day with high temperature and good light to level the soil and irrigate it to keep the relative humidity of the soil at 60% to 85%. After that, the soil is deeply plowed once to make the lime nitrogen particles fully contact with the soil, cover the stuffy soil with a transparent film for 12 days, then remove the film for ventilation, plow the soil and prepare the site, and let it dry for more than 10 days before planting;

[0046] (2) Seed stem treatment:

[0047]

[0048] (3) Liquid spraying: After planting the sugarcane seeds obtained in the above (2) seed stem treatment: treatment 1-treatment 5, when the sugarcane is not diseased or the disease shows initial symptoms, use 220 times of bot...

Abstract

The invention belongs to the technical field of plant protection, and specifically discloses a method for controlling sugarcane red rot. The method comprises three steps: (1) disinfecting soil; (2) processing seed and stem; (3) spraying pesticide. Soil disinfection, seed and stem processing, and pesticide spraying are carried out to control the pathogen and propagation of sugarcane red rot, and thus the sugarcane red rot is well controlled. The provided method for controlling sugarcane red rot can well control sugarcane red rot, reduces the harms of red rot to sugarcane during the growth process, and largely reduces the using amount and application frequency of chemical pesticide.

Description

technical field [0001] The invention belongs to the technical field of plant protection, in particular to a method for preventing and treating red rot of sugarcane. Background technique [0002] Sugarcane red rot is one of the earliest sugarcane diseases known to people. It occurs commonly in various sugarcane producing areas in the world, mostly in the late growth period of sugarcane. It mainly damages leaves, leaf sheaths, and stem roots, among which stems and leaves are seriously damaged. Leaf infection initially produces small red spots on the midrib, and then spreads into fusiform spots. The surrounding spots are red and black, and the middle part is yellowish white. There are scattered small black spots on them, which are the bristles produced on the conidia of the pathogen. When the leaf sheath is infected, there are large red irregular spots at the beginning, which gradually turn into yellowish white, and sometimes small red lesions also appear on the surface of the...
