Abstract

The invention discloses a citrus slow decline disease control method, which is characterized in that an emulsion in water compounded by amino-oligosaccharin and fosthiazate is used for irrigating roots, and the application amount per mu is 500-1000 mL. Tests show that the emulsion in water compounded by fosthiazate and amino-oligosaccharin has a good prevention and treatment effect on a main pathogen semipuncture nematode of the citrus slow-decline disease, the prevention and treatment effect reaches 79.15% and is superior to that of single agents of fosthiazate and amino-oligosaccharin, and the emulsion in water can be widely applied and popularized to prevention and treatment of the citrus slow-decline disease.

Description

technical field [0001] The invention belongs to the field of fruit tree disease and insect pest control, and in particular relates to a method for preventing and treating citrus slow senescence disease. Background technique [0002] Citrus chronic senescence ( Tylenchulus semipenetrans ) is a major disease of citrus production in the world, widely distributed in citrus producing areas of the world, and its pathogen is mainly citrus semi-piercing nematode. Citrus semi-piercing nematodes are small and cannot be observed with the naked eye. They can sneak into the fibrous roots of citrus and invade the cortex of citrus roots, stop the development of roots, and no longer produce new absorbing roots, thereby affecting the supply of water and nutrients, resulting in The root system is swollen and deformed, and symptoms such as root nodules and root knots are formed in severe cases; the initial symptoms of the above-ground parts are not obvious, mainly accompanied by yellowing due...
