Application of farnesol as antibacterial synergist in preventing and controlling plant grey mold

Abstract

The invention relates to the field of plant disease prevention and control, in particular to application of farnesol as an antibacterial synergist in preventing and controlling plant grey mold. Particularly, the antibacterial synergist is applied to preventing and controlling the grey mold with a benzimidazole bactericide or triazole bactericide. The farnesol has the synergistic action to the bactericide, can improve the virulence of the bactericide by being used mixing with the bactericide, improves the sensibility of a drug-resistant strain to the bactericide and the prevention and control effect of the bactericide to the field drug-resistant grey mold, reduces the dosage of the bactericide and provides a new method to development and application of a novel preparation of the existing bactericide. Meanwhile, the farnesol is an extract of natural plants and is environmentally friendly. The invention provides a novel application of the drug, can be used for disease prevention and control in the agricultural field and provides a new way to grey mold field drug-resistant government.

Description

technical field [0001] The invention relates to the field of plant disease prevention and control, in particular to the application of farnesol as a bactericidal synergist in the prevention and treatment of botrytis cinerea. Background technique [0002] Botrytis cinerea, also known as Botrytis cinerea, is widely distributed all over the world. Botrytis cinerea can infect more than 200 economic crops and ornamental plants including Solanaceae, Cucurbitaceae, Rosaceae, Leguminosae, etc., especially on vegetables, and can occur in all parts of the host plant, causing The economic loss is generally 10% to 20%, and in severe cases it can reach more than 60%, or even no harvest. However, due to the large sporulation of Botrytis cinerea, a wide range of hosts, a large amount of genetic variation, and the extensive use of chemical agents in disease control, Botrytis cinerea has become resistant to commonly used chemical fungicides in the past few decades. Seriously, even resistan...

Problems solved by technology

[0004] However, due to the continuous use of some fungicides for many years, the resistance of Botrytis cinerea in the field is serious, and the synergistic effect of the above-mentioned synergists on these fungicides is very limited.

At present, there are few reports on effective fungicide synergists for field-resistant Botrytis cinerea. The development and application of such substances will be of great significance for effectively controlling the harm of field-resistant Botrytis cinerea populations
