Embodiment 1

[0012] Embodiment 1 Utilizes wood vinegar to control citrus green spot

[0013] 1. Crop cultivation and environmental conditions

[0014] The orchard is flat. The level of fertilizer and water management is basically the same, and the light conditions are good. Hovenia trifoliata, tree age 8-10 years old, row spacing 4×3m, 55 plants per mu, average plant height 2.45m, crown width 2.06m. There has been a lot of rain recently, and the occurrence of citrus green spot is moderate, and the disease has already occurred when the test was carried out. No fertilization or irrigation was applied during the experiment. 2. Experimental Design and Arrangement

Abstract

The invention discloses a method for preventing and treating green spot of citruses by using wood vinegar. The method is characterized by comprising the steps: uniformly mixing 99% mineral oil, the wood vinegar and water, wherein in the uniformly-mixed medicated solution, the final concentration of the 99% mineral oil is diluted by 200 to 300 times, and the final concentration of the wood vinegar is diluted by 30 to 40 times; and spraying citrus fruit trees with the mixed medicated solution. Through mixing the wood vinegar and the mineral oil, the control effect on the green spot of the citruses is improved greatly, meanwhile, the consumption of agents is lowered greatly, and the cost is reduced; and by the method, the residual of chemical pesticides on crops can be effectively avoided, and the pollution to environments caused by the chemical pesticides is reduced. The method is low in cost, wide in source of materials, light in environmental pollution and harmless to human bodies, thereby having a very good popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of fruit tree diseases and insect pests, and in particular relates to a method for preventing and treating citrus green spot diseases by using wood vinegar. Background technique [0002] Green spot is an important disease of citrus, which is caused by the parasitism of Apatococcus lobatus, a genus of green algae. At the beginning of the disease, small yellow-green spots appear on the leaves and fruits, and then gradually expand to the surroundings, forming uneven Regular plaques heal with each other, covering the whole leaf and the whole fruit. When the air humidity is low, the lesion is in the form of leprosy, which has a great impact on the photosynthesis of citrus, and then seriously affects the tree vigor, fruit quality and yield. At present, the control of green spot disease mainly relies on chemical pesticides, but the effect of chemical control is not satisfactory. In additio...
