A kind of bactericidal composition containing spirulina and propamocarb and its application

Abstract

The invention discloses a sterilization composition containing spiroxamine and propamocarb and an application thereof. According to the sterilization composition, the spiroxamine and the propamocarb serve as main active ingredients, and the mass ratio of the spiroxamine and the propamocarb is (1-90):(1-90). The sterilization composition can be applied to controlling cereal diseases, fruit tree diseases and vegetable diseases, and has the high synergistic interaction effect, the pesticide resistance of germs is overcome and delayed, the sterilization speed is high, the lasting period is long, application cost is reduced, and the controlling effect is obviously superior to the use effect of the single dosage of the sterilization composition. The sterilization composition can be used for controlling fungal diseases of crops, and particularly can be used for controlling fungal diseases such as wheat powdery mildew, rust diseases, downy mildew and late blight, and the effect is better than the use effect of the single dosage.

Description

Technical field: [0001] The invention relates to a fungicidal composition and its application, in particular to a fungicidal composition with spirulina and propamocarb as main active ingredients and its application. Background technique [0002] Spiroxamine, chemical formula: C18H35NO2, chemical name: N-ethyl-N-propyl-8-tert-butyl-1,4-dioxaspiro[4.5]decane-2-methylamine. Structural formula: [0003] [0004] Spirulina is a substituted amine fungicide and a sterol biosynthesis inhibitor, which mainly inhibits the synthesis of C-14 deoxymethylase of pathogenic bacteria. The control objects are wheat powdery mildew and various rusts, barley moire and stripe disease. Spirulina is a new type of systemic foliar fungicide, which has special effect on powdery mildew. It acts quickly and lasts for a long time, and has both protective and therapeutic effects. [0005] Propamocarb, molecular formula: C9H20N2O2, chemical name: propyl N-[3-(dimethylaminopropyl)amino]formate. Stru...

Problems solved by technology

[0008] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge
