Description

technical field

[0001] The invention belongs to the technical field of prevention and control of fruit tree diseases and insect pests, in particular to a botanical pesticide for preventing and treating apple tree rot. Background technique

[0002] my country's apple production accounts for 46% of the world's total production (2008), ranking first in the world. The development of apples and the apple industry has made great contributions to the country's economic development and social progress. However, the occurrence of apple tree rot has become an important factor restricting the production and export of apples in my country, causing serious yield and economic losses. Apple tree rot disease is widely distributed in our country, it is seriously harmful, and it is difficult to control it. It is called "cancer" of apple trees. When the disease is mild, it causes bark rot, tree vigor weakens, and fruit yield and quality decline. When it is severe, it causes the main pole, lar...

[0026] Botanical pesticide of the present invention is used for field preventive effect investigation of apple tree rot: In 2013-2014, 8-13 years old apple trees in Jingning, Gansu Province were tested for rot prevention. Wet powder 100 times liquid and blank are controls, and the test results are shown in Table 1 below:

[0027] Table 1 Investigation of the field preventive effect of botanical pesticides on apple tree rot

[0028]

[0029] The results show that the botanical pesticide of the present invention has a field control effect of 99% in 2 years, which is obviously higher than the control effect of 100 times liquid of 40% thiram arsenic wettable powder, and the wound treated with the botanical pesticide of the present invention, after 3 months The width of wound callus formation was 1.7cm, obviously better than 0.8cm of 100 times liquid of 40% thiram wettable powder.
