Description

The bactericidal composition of a kind of Han famoxadone and Boscalid and application thereof
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially Yi Zhong Yi famoxadone and Boscalid be main active bactericidal composition and application thereof.
Background technology
Famoxadone (Famoxadone), chemical name: 3-anilino--5-methyl-5-(4-Phenoxyphenyl)-1,3-azoles quinoline-2,4-diketone, molecular formula: C 22h 18n 2o 4, chemical structural formula is as follows:
Famoxadone Shu oxazole series bactericidal agent, has protection, treats, roots out, permeates, systemic activity.Mechanism of action is inhibitor of energy, and namely Mitochondrial electron transmission suppresses system.For wheat, barley, pea, beet, rape, tomato, capsicum, melon, potato.Prevent and treat the important disease in Ascomycetes, Basidiomycetes, Oomycete, as powdery mildew, downy mildew, net blotch, rust, glume blight, late blight etc., and can be composite with other protective fungicides.Yin Er, famoxadone is widely used a kind of bactericide.
Boscalid (Boscalid), the chloro-N-of chemical name: 2-(4-chlordiphenyl-2-base) nicotinanilide, molecular formula: C 18h 12cl 2n 2o, chemical structural formula is as follows:
Boscalid belongs to respiration inhibition series bactericidal agent; fungicidal spectrum is wider; the mechanism of action is shifted in plant by blade face infiltration; suppress mitochondrial succinate acid esters dehydrase; hinder tricarbonic acid cycle, make amino acid, sugar lacks, energy reduces, the division of interference cell and growth; there is neural activity to disease, there is protection and therapeutic action.Suppress spore germination, the extension of bacterium pipe, mycelial growth and spore mother cell to form the Main Stage of conk and breeding, bactericidal action is directly caused by parent active agent, does not have corresponding metabolic activity.Almost there is activity to all types of fungal disease, to preventing and treating, powdery mildew, gray mold, stalk break and various rots etc. are very effective, and also effective to the resistance bacterium of other medicaments, be mainly used in the control comprising the diseases such as rape, grape, fruit tree, vegetables and field crop.
At present, along with the change of pattern of farming, disease occurrence degree, the generation quantity of melon and fruit, vegetables, cereal crop all increase, and are are objectively preventing and treating difficulty increasing; On the other hand, SM, under the medicament selection pressure continued, cause the resistance of pathogen to rise year by year, the control efficiency of single dose is had a greatly reduced quality; 3rd, the speed to introduce of current new varieties of pesticides obviously declines, and lacks new action target medicament; 4th, strict gradually due to environmental requirement, portioned product is limited to use, and causes medication selectivity to become less.In a word, how effective control plant disease is the important topic that vast plant protection work person faces.

Yong famoxadone and the former medicine of Boscalid carry out biological activity determination.
In indoor employing mycelial growth rate method, measure different agents to the EC of bacterial strain 50value, adopt co-toxicity coefficient computational methods, calculate the co-toxicity coefficient (CTC) of mixture, determine the building performance of mixture, circular is as follows:
With single dose a certain in mixture for standard agent (selects EC usually 50junior), calculate:
Single dose toxicity index=standard agent EC 50/ certain single dose EC 50× 100
Toxicity index × B single dose proportion in mixture of toxicity index × A single dose proportion+B single dose in mixture of theoretical toxicity index=A single dose
The EC of actual measurement toxicity index=standard single dose 50the EC of value/mixture 50value × 100
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100
When co-toxicity coefficient classification: CTC is greater than 120, mixture has synergetic, and be antagonism when CTC is less than 80, CTC is summation action between 80-120.
