Problems solved by technology

[0003] The above methods (3), (4) and (5) cannot fundamentally solve the problem. The conventional pesticides used in method (6) have poor control effects on sugarcane smut, and cannot guarantee that sugarcane will not be re-infected
Therefore, there is no effective control method for smut in China at present, and the authorization number is the invention of CN102899380B: Bacillus subtilis HAS and its application in the prevention and treatment of sugarcane smut The strains provided have better control of sugarcane smut However, its control effect on smut is only limited to pot experiments, and there are still many problems to be explored in the promotion of the use of biocontrol strains to control sugarcane smut

Embodiment 1

[0017] Implementation location: Litang Town, Binyang County, Guangxi

[0018] Implementation time: March 27, 2013

[0019] Implementation area: 5 mu

[0020] The implementation steps are as follows:

[0021] (1) Soil preparation: ditching and ridging;

[0022] (2) Seed stem treatment:

[0023]

[0024] (3) Base fertilizer application: first sprinkle 3 tons / mu of quicklime in the planting ditch, cover it with plastic film, and press it tightly; after 7 days, continue to apply 2 tons / mu of fully decomposed chicken manure, and finally apply 20-50kg For compound fertilizer per mu, the nitrogen, phosphorus and potassium ratio is 15-7-10; the base fertilizer is nitrogen-controlling compound fertilizer.

[0025] (4) Growth period management: Spray glucose or sucrose on the leaves of sugarcane tillering stage at a spray rate of 50g / mu; spray "Luzhen" liquid carbon fertilizer on leaves at the jointing stage of sugarcane at a spray rate of 10g / mu.

[0026] According to the above...

Abstract

The invention discloses a method for controlling smut of sugarcane. The method specifically comprises the following steps: 1, performing soil working; 2, processing seed stems; 3, applying a base fertilizer; and 4, performing growing time management. The control technology provided by the invention mainly involves selection of proper medicaments for preventing seed stem infection diseases through seed stem processing at an early stage and regulation and control of carbon-nitrogen ratio of crops through applying the base fertilizer and spraying glucose, cane sugar or a liquid carbon fertilizer at a later stage so as to reduce risks of the diseases. When the technology is used for controlling smut, the control effect can be more than 75%, and the popularization value is quite large.

Description

technical field [0001] The invention belongs to the technical field of plant protection, in particular to a method for preventing and treating sugarcane smut. Background technique [0002] Sugarcane smut is also known as sugarcane whip smut and powdery smut. The obvious feature of the disease is that the tip of the sick cane has a black whip that rolls down, ranging from a few centimeters to tens of centimeters in length. The center of the whip is a core column composed of parenchyma or vascular tissue, surrounded by a layer of chlamydospores. In the initial stage of formation, the diseased penis is covered with a layer of silver-white film, and then it ruptures and emits a large amount of black powder, and finally only the stem remains. Infected seed sugarcane germinates early, with small stems, slender leaves, light green, increased tillers, and black spikes on the latter tillers. The invention belongs to the technical field of plant protection, in particular to a metho...
