Description
Technical Field
The invention relates to the field of agricultural pest control, in particular to a compound medicament for controlling apple tree rot and a preparation method thereof.
Background
At present, the planting area of apple trees in China is about 2800 ten thousand mu, wherein the tree age of 20-30 years accounts for about 70%, and fruit tree rot becomes the primary disease of apple trees in the apple tree management process. The apple tree canker is an air-borne disease, canker mainly harms branches and trunks of apple trees to form canker spots, and the apple tree canker is dead when serious, meanwhile, the germ has long infection period, conidia exist all the year round in the field and can be infected at any time, the fruit tree canker is a fruit tree common disease with wide occurrence range and serious harm degree, and the fruit tree canker is a fruit tree common disease with mild fruit trees, big branches and small branches are died, the fruiting capacity is reduced sharply, the quality is reduced, the fruiting period is shortened, the heavy fruit trees are died, and the whole fruit tree is died in some cases.
The existing commonly used chemical prevention and treatment is to perform prevention and treatment through biological pesticides, such as antifungal agents and the like, spraying a spading medicament on the whole apple tree, smearing the medicament after treating scab, and applying the medicament 7-10 times a year to effectively prevent and treat the apple tree canker. In order to avoid the drug resistance of germs and reduce the prevention and treatment effect, the pesticides can be alternately used for prevention and treatment, but the method not only increases the labor cost, but also needs to apply the pesticides for 3 to 4 times, and the prevention and treatment effective rate can only reach about 78 percent.
