Preparation and application method of insecticide for treating apple tree canker

Abstract

The invention discloses a preparation and application method of insecticide for treating apple tree canker. The preparation materials of the insecticide comprise wood tar stock solution, Tween or alcohol, and distilled water, wherein the wood tar stock solution, Tween and distilled water are prepared into insecticide in a volume ratio of a:b: (a+b); a and b are require to meet the condition that bis greater than or equal to a and smaller than or equal to 4a; or the alcohol, distilled water and wood tar stock solution are prepared into insecticide in a volume ratio of 15c:c:d; c and d are required to meet the condition that d is greater than or equal to 16c and smaller than or equal to 64c. The insecticide is applied according to the following step: firstly scraping branch and trunk partssuffer from apple tree canker, then continuously scraping branch and trunk parts around disease speckles with a disinfected cutter, and finally applying the insecticide to the parts where disease speckle are scrapped with a brush in January to February, March to April and July every year. The insecticide is simple to prepare, convenient to use, low in cost, and small in environmental pollution, and a large quantity of experiments approve that the insecticide has good treatment effect on apple tree canker when being used according application method.

Description

technical field

[0001] The invention relates to a preparation method and a use method of a medicament for treating fungal parasitic diseases of fruit trees, in particular to a preparation method and a use method of a medicament for treating apple tree rot. Background technique

[0002] Apple trees are deciduous trees, and the branches of wild apple trees can be as high as 15 meters. In order to facilitate the agronomic management of apple trees, artificially cultivated apple trees are generally only 3 to 5 meters high. degree of shedding. Its fruit is generally red, and the fruit is rich in minerals and vitamins, and is one of the most commonly eaten fruits for people.

[0003] Apple trees are mainly distributed in Liaoning, Hebei, Shanxi, Shandong, Shaanxi, Gansu, Sichuan, Yunnan, Tibet and other places in China. According to the data released by the National Bureau of Statistics in 2012, my country's apple tree planting area is as high as 2.231 million hectares, accounti...
