Abstract
The invention discloses a medicament for disinfecting a plum tree, a live wood disinfecting method and application of the medicament for disinfecting the plum tree. The medicament for disinfecting the plum tree contains the following active ingredients in weight proportion: 0.0005-0.002wt% of ribavirin, 0.00005-0.0001wt% of abscisic acid and 0.1-1wt% of chitosan. The invention also relates to a live wood disinfecting method of the medicament for disinfecting the plum tree and application of the medicament for disinfecting the plum tree in prevention and control of one or more than one plant viruses of prune dwarf virus (PDV) and prunus necrotic ringspot virus (PNRSV). Compared with the prior art, the medicament for disinfecting the plum tree has a good prevention and control effect, dosage can be reduced, and pollution to the environment can be reduced; besides, a scientific method is utilized for carrying out live wood disinfection on the plum tree, especially local specialty prunus salicina in Guizhou province, viruses on part of branches bearing fruits and blades are killed or inhibited, and harm of the viruses is reduced, so that yield is increased, and fruit flavour is improved.
Description
technical field [0001] The invention relates to a plum tree antivirus agent, a living wood antivirus method and an application thereof, belonging to the field of fruit tree pest control. technical background [0002] Plant virus disease is the main disease in agricultural production, seriously endangering the yield and quality of crops. Once the plant virus disease shows symptoms, it is very difficult to treat. Therefore, prevention must be given priority to, and antiviral drugs are used to inhibit the proliferation of viruses, slow down or Mitigate the damage of viruses to crops. [0003] Sand hollow plum is a characteristic fruit in Shazi Town, Yanhe County, Guizhou Province. It has been planted for a long time and is vulnerable to pests and diseases during the cultivation process. Viruses, due to the harm of viral diseases, seriously affect the yield and quality of the fruit, resulting in abnormal fruit shape, reduced taste, reduced quality, and reduced yield. [0004] ...
