Abstract

The invention relates to a plant essential oil emulsifiable concentrate for inhibiting / killing phytopathogenic fungi, which consists of the following medicines in parts by weight: 8-12 parts of plant essential oil, 20-30 parts of organic solvent, and 2-6 parts of emulsifier. The invention has the advantages of broad-spectrum bactericidal activity and can be widely used in the prevention and control of agricultural fungal diseases so as to meet the requirements of organic vegetables and green vegetables.

Description

technical field [0001] The invention belongs to the field of plant protection, mainly the field of biological source pesticides, and in particular relates to a preparation method of plant essential oil emulsifiable concentrate for inhibiting / killing phytopathogenic fungi. Background technique [0002] According to the investigation of the Food and Agriculture Organization of the United Nations, the damage of pests in the world reduces the grain production by 20% to 40% every year, and the resulting economic losses amount to 120 billion US dollars. In order to prevent pests and diseases, chemical pesticides have been used in agricultural and forestry production for a long time to control their occurrence and reduce losses in agriculture and forestry. However, chemical pesticides have a series of serious problems such as insurmountable environmental pollution, pesticide poisoning, and pest resistance. According to reports, the annual use of pesticides in my country is 800,000 ...
