In this paper, the effect of 60% sodium dichloroisocyanurate on the control of apple tree rot was discussed by the application method of scraping patch and spray. The results showed that the two application methods had certain control effects on apple tree rot. The effective concentrations of spraying were 0.5, 0.6, 0.75 g / L, which were 66.09%, 69.61% and 73.67%, respectively. There was no significant difference in the efficacy of drug treatment. The effective concentrations applied were 3 g / L and 6 g / L were 81.38% and 85.00%, respectively, which were not significantly different from the control treatment. The use of the drug is more than the drug, but the application frequency is small, the control effect is good, and should be promoted.
As the age of the tree increases, the incidence of rot disease increases, and the rot disease not only weakens the trees, but even destroys the garden. The key to prevention and control of rot disease: First, maintain strong trees; Second, do tool disinfection, wounds, wounds on wounds, anti-corrosion film, protect the growth of healing tissue, anti-corrosive infection; Third, timely cure after scraping, should be timely protection. It can be sprayed to protect trees, destroy harmful bacterial sources, penetrate viruses, and stop the virus. Replication and transmission paths. Prevent bacteria from re-infecting and improve the spirit of the plant.
Sodium dichloroisocyanurate is a white powder or a granulated solid. It is the most sterilized, efficient and safe disinfectant in oxidizing bactericides, and also the main product of chloroisocyanuric acid. It can kill various pathogenic microorganisms such as bacterial spores, bacterial propagules and fungi, and has a special killing effect on hepatitis virus. It can quickly kill and strongly inhibit blue-green algae in circulating water, cooling towers, pools and other systems. red. Algae such as algae and seaweed. It has a complete killing effect on sulfate-reducing bacteria, iron bacteria and fungi in circulating water systems.
