Problems solved by technology

Tobacco is an important economic crop, and its main economic value comes from tobacco leaves. If tobacco suffers from bacterial angular leaf spot, if it is not cured in time, the quality of tobacco flowers and leaves will be greatly reduced, and the economic benefits will drop sharply.

experiment example

[0011] Select 8 MS medium and divide them into control group and experimental group, 2 in the control group without adding MS medium; 6 in the experimental group, add 50mg C 8 h 4 N 8 Experiment 1 group, 100mg C 8 h 4 N 8 Experimental group 2, 200mg C 8 h 4 N 8 There were 3 groups of experiments, two in each group; then streak inoculation, culture observation and record data of 8 culture mediums were carried out to prepare the following table 1.

[0012] Table 1:

[0013]

[0014] Analysis of the data in Table 1 shows that C 8 h 4 N 8 Can effectively inhibit the reproduction of angular spot bacteria.

Embodiment

[0016] A tobacco planting field suffering from tobacco mosaic leaf spot disease was selected to verify the embodiment. Divided into three groups for verification, the first group was sprayed with water; the second group was sprayed with 1:2500 diluted concentration of C 8 h 4 N 8 solution; the third group is to spray the solution of 1:500 dilution of the composition described in claim 2. Among them, the second group and the third group start with C 8 h 4 N 8 Note that the concentrations are equal.

[0017]

[0018] It is known from the above examples that the present invention can effectively restore the damage of tobacco leaves caused by tobacco leaf spot disease, immediately restore economic losses, and obtain high-quality tobacco leaves.

Abstract

The invention relates to the field of preventing and controlling bacterial angular leaf spot of tobacco and discloses a compound capable of effectively resist the bacterial angular leaf spot of tobacco. The compound is 5'-(pyrazin-2-yl)-2H, 4'H-3, 3'-bi(1, 2, 4-triazole), and a chemical formula is C8H4N8. The invention further discloses a composition capable of effectively resist the bacteria angular leaf spot. The composition comprises, by mass, 5 parts of C8H4N8, 15 parts of rapeseed oil and 5 parts of fatty alcohol polyoxyethylene ether. It is verified that 5'-(pyrazine-2-base)-2H, 4'H-3, 3'-bi(1, 2, 4-triazole) which is a main active ingredient can effective resist pathogenic bacteria of the bacterial angular leaf spot; by adding the rapeseed oil, sterilizing effect of the compound can be improved effectively; by matching with the fatty alcohol polyoxyethylene ether, a better role can be played in improving wettability, emulsifying performance and foaming performance of mixed liquid in the process of actual spraying.

Description

technical field [0001] The invention relates to the field of prevention and treatment of tobacco leaf spot disease. Background technique [0002] Bacterial angular spot mainly affects leaves and melon strips. The damaged leaves are initially water-soaked light green and then light brown, and become polygonal due to the limitation of leaf veins. In the later stage, the lesions are off-white and easy to perforate. When the humidity is high, white mucus is produced on the lesions. Lesions on stems and melon strips are water-soaked at first, nearly round, and then light gray. Cracks often occur in the middle of the lesion, and bacterial pus is produced when it is wet, eventually causing the leaves to die. Tobacco is an important economic crop, and its main economic value comes from tobacco leaves. If tobacco suffers from bacterial angular leaf spot and is not cured in time, the quality of tobacco leaves will be greatly reduced, and the economic benefits will drop sharply. C...
