Problems solved by technology

[0002] The pathogen of leaf mold is Cladosporium chrysogenum. Its growth environment is at a temperature of 20-25°C and a humidity of more than 85%. It can spread to the whole field in more than 10 days from scratch, especially now that growers want to achieve high yield. Objectives: Excessive planting density, poor ventilation between plants, excessive watering, excessive humidity, and long condensation on leaves are all beneficial to the infection and expansion of pathogens, which can aggravate the occurrence of diseases

Abstract

The invention discloses a compound for preventing white peony root leaf mould, and belongs to the field of prevention of plant diseases and insect pests. The compound comprises, by weight, 60-100 parts of biogas slurry, 15-25 parts of chlorothalonil, 10-20 parts of a litsea cubeba extract, 10-20 parts of an clove extract, 10-20 parts of a perilla frutescens extract, 5-10 parts of monopotassium phosphate, 2-4 parts of boronic acid, 1-2 parts of chitosan and 1-3 parts of diatomite. The compound can prevent intrusion and pathopoiesia of pathogens of leaf mould and also have the function of enhancing plant growth, disease resistance of plants is achieved, and the effects of prevention and control are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant disease and insect pest control, and in particular relates to a composition for preventing and treating white peony leaf mold. Background technique [0002] The pathogen of leaf mold is Cladosporium chrysogenum. Its growth environment is at a temperature of 20-25°C and a humidity of more than 85%. It can spread to the whole field in more than 10 days from scratch, especially now that growers want to achieve high yield. Objectives: Excessive planting density, poor ventilation between plants, excessive watering, excessive humidity, and long condensation on leaves are all beneficial to the infection and expansion of pathogens, which can aggravate the occurrence of diseases. [0003] Leaf mildew of Radix Paeoniae Alba mainly damages the leaves of Radix Paeoniae Alba, primary circular brown lesion, primary circular purple-brown lesion, 6-15mm in size, slightly light brown ring pattern behind, dark purple...
