Method for treating bacterial canker of tomato

Abstract

The invention relates to a method for treating bacterial canker of tomato, which comprises the following steps that firstly, dry tomato seeds which are infected with bacterial canker are obtained through detection; then, streptomycin sulfate and water are prepared into a solution with the weight percentage of 0.05%-0.15% for standby; next, the dry tomato seeds which are infected with bacterial canker are soaked into the prepared streptomycin sulfate solution, the temperature of the solution is maintained between 20-25 DEG C, and the mixture is stirred for 3-5 hours; then, the well soaked tomato seeds are taken out and flushed with clear water; and finally, the tomato seeds are aired, and are detected for the infection condition. The method has the advantages of obvious treatment effect, simple treatment method and low cost.

Description

technical field [0001] The invention relates to the field of horticultural plant disease prevention and control, in particular to a treatment method for tomato canker. Background technique [0002] Tomato canker is a devastating disease. Since it was first discovered in my country in the 1980s, it has gradually spread to the whole country. In recent years, tomato canker has shown an outbreak trend, and tomato production in severe cases has decreased by 25% to 75%. %. my country has listed it as a quarantine object to prevent and control the spread of the disease. Tomato canker not only brings losses to tomato commercial production, but also threatens tomato seed production enterprises. Because the inner and outer layers of seeds can carry bacteria, it forms long-distance transmission, and the general seed transmission rate can reach 1-5%. The seed transmission rate of harvested seeds can reach 53.4%. The seeds produced by many tomato seed production enterprises are infected...

AI Technical Summary

Problems solved by technology

The prevention and control method of existing tomato canker seed mainly is: 1, fermentation method; 2, acetic acid soaking method; 3, warm soup soaking method; 4, sodium hypochlorite solution soaking method; The suspected seeds are disinfected, and the control effect is average

In addition, there is also a method of seed dressing with 0.4% DT fungicide, soaking the seeds in warm water at about 40°C for 3 to 4 hours, then soaking them in 1% potassium permanganate solution for 10 to 15 minutes, or directly using 72% agricultural streptomyces Seed soaking in 2000 times solution for 2 hours can also be used as a method for the prevention and treatment of tomato canker, but these methods are not effective in removing the pathogens carried on the infected canker seeds. very huge
