Application of amitriptyline as bactericidal synergist in plant disease control

Abstract

The invention relates to the field of plant disease control, in particular to application of amitriptyline as a bactericide synergist in plant disease control. The occurrence of oomycete disease resistance to fungicides and even multi-drug resistance in the field is reported, resistance including an uncoupling agent is often associated with the multi-drug resistance, the management of such resistant groups is very difficult, and great harm is brought to agricultural production. According to the application of amitriptyline as the bactericide synergist in plant disease control, the amitriptyline and a diarylamine bactericide, substituted benzene bactericides or piperidinothiazole isoxazoline bactericides, are found to have good synergism on the combined toxicity of phytophthora resistant mutants after being mixed, the toxicity of the bactericides can be effectively improved, the sensitivity of drug resistant strains to the bactericides is restored, the usage amount of the bactericides is reduced, and a new method is provided for the development and application of new preparations of existing bactericides. The application provides a new application of farm chemical, can be used for disease control in the agricultural field, and provides a new way for disease resistance management in the field.

Description

technical field [0001] The invention relates to the field of plant disease control, in particular to the application of amitriptyline as a bactericidal synergist in plant disease control. Background technique [0002] Plant blight is a devastating disease, and its pathogen Peronophthora.spp has a wide range of hosts. Common diseases include potato late blight, tomato late blight, pepper blight, litchi downy mildew, soybean blight, etc. Among them, potato late blight has a great impact on my country's agricultural production. pose a great threat. The disease first received widespread attention in Europe in 1845, when an outbreak of late blight caused the historic Irish Famine, displacing and even killing millions. In addition, other diseases such as pepper blight have been widely distributed in the pepper growing areas of China. Capsicum can be infected with blight at the seedling stage and adult plant stage, and it expands rapidly in the field. Phytophthora has caused huge...
