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 los

Example Embodiment

[0027] Example one

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

[0029] Implementation time: March 26, 2013

[0030] Implementation area: 5 mu

Example Embodiment

[0031] The implementation method includes the following 3 aspects:

[0032] (1) Soil disinfection: Choose a sunny day with high temperature and good sunlight to level the soil and irrigate the soil to keep the relative humidity of the soil at 60%-85%. After 2 days of irrigation, evenly spread lime nitrogen, the application amount is 40 kg / After that, make a deep plowing of the soil to make the lime nitrogen particles fully contact the soil, cover the dull soil with a transparent film for 10 days, then remove the film for ventilation, plow the soil to prepare the ground, and dry it for more than 10 days for planting;

[0033] (2) Seed stem treatment:

[0034]

[0035] (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 onset or the disease shows initial symptoms, use 150 times the plant-derived medicine and 0.36% bitterness. The medicine solution obtained by mixing 1000 times solut...

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...
