Problems solved by technology

[0003] Traditional control methods use 1000-2000 times liquid of 50% benlaite wettable powder or 400-600 times liquid of 30% Lvdebao suspension concentrate, 500-800 times liquid of 75% chlorothalonil wettable powder, 66.8% mildew 1000 times of liquid for prevention and control generally needs to be sprayed 3-5 times. Over the years, long-term use of the above agents has resulted in serious resistance; at the same time, farmers privately add more and indiscriminately add other agents when using drugs, which not only greatly increases the cost of using drugs , the loss of pesticides is serious, and environmental pollution is urgent, especially the pesticide residues in crops after pesticide application exceed the standard, seriously affecting people's physical and mental health

Embodiment 1

[0020] Example 1: Indoor efficacy test of flufenapyroxad and nano-carbon on sugarcane tip rot.

[0021]

[0022] It can be seen from Table 1 that after the addition of nano-carbon, flufenapyroxamide has a significant control effect on sugarcane tip rot pathogens. When the amount of nano-carbon added is 8-15g, flufenapyroxad has different degrees of efficacy Improvement, taking into account the cost factor, the tentative addition of nano-carbon is 8-15g.

Embodiment 2

[0023] Example 2: Field efficacy test of flufenapyroxad and nano-carbon on sugarcane tip rot

[0024] The test plan is shown in Table 2:

[0025]

[0026] After the last pesticide application, the incidence of sugarcane tip rot was investigated 7 days, 14 days, and 21 days respectively, and the yield was measured when the sugarcane was received. The results are shown in Table 3.

[0027]

[0028] It can be seen from the data in Table 3 that the use of treatment 1-4, that is, the combination of the patented technology flufenapyramide and nano-carbon of the present invention, is superior to the conventional agents of treatment 5 and 6 in the prevention and treatment of sugarcane tip rot, and both treatment 1 and treatment 3 are at When used before the onset, the control effect reached more than 85% in 7 days, and the control effect was more than 90% in the 14-day and 21-day investigations, indicating that the duration of effect is longer; the two treatments applied after t...

Abstract

The invention discloses a method for preventing and treating sugarcane pokkah boeng disease. Concretely, when sugarcane blades are not subjected to diseases or preliminary symptoms of diseases arise, prevention and treatment are performed by utilizing fluxapyroxad liquid and nano carbon liquid in matching with organosilicon, the concentration of the fluxapyroxad liquid is 1.5-2.5 g / L, and the chemical liquid amount per mu is 45-60 kg; the concentration of the nano carbon is 8-15 g / L, and the chemical liquid amount per mu is 45-60 kg; the concentration of the organosilicon is 5-10 g / L and is matched with fluxapyroxad and tricyclazole in use; the chemical application temperature is 20-26 DEG C, and the chemical application humidity is 30-60%. By utilizing the method, the chemical liquid utilization rate can be improved effectively, the effect is obvious, the comprehensive prevention effect can be cover 80%, and the method has very good popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of plant protection, in particular to a method for preventing and treating sugarcane tip rot. Background technique [0002] Sugarcane tip rot is a phenomenon in which the infected young leaves are chlorotic and yellow at the base, narrower than normal leaves, and the leaves are significantly wrinkled, twisted or shortened. Fusarium moniliforme Sheldon); sexual stage Ascomycetes Gibberella genus Gibberella Fujikura ( Gibberella fujikuroi (Saw.) Wolle.) caused. Sugarcane tip rot mainly affects the young leaves at the top of the tip, but also infects the leaf sheaths and cane stems. In the early stage of the disease, the base of young leaves turns chlorotic and yellow, the leaves are narrower than normal leaves, and reddish-brown longitudinal stripes of different lengths are produced, and the rear stripes are split, and the leaves are obviously wrinkled, twisted or shortened, and in severe cases, they are ...
