Description
Technical field
The present invention relates to a kind of agricultural chemicals, refer in particular to a kind of composite bactericide of preventing and treating fruits and vegetables oomycetes disease.
Background technology
Fruits and vegetables oomycetes disease is by due to the Mastigomycotina Oomycete pathogen infection, wherein mould with epidemic disease, downy mildew, rotten oomycetes such as mould are the important pathogen of fruits and vegetables, fruit tree crops such as the main fruit trees and vegetables of kinds such as harm Cruciferae, Solanaceae and Curcurbitaceae and grape, cause damping off, pythium rot, eqpidemic disease, cotton disease, downy mildew and the root rot etc. of fruits and vegetables, cause the significantly underproduction even total crop failure.Chemical control is the main means of control oomycetes disease and the important leverage of crop high yield, produces the bactericide of going up control fruits and vegetables oomycetes disease at present and mainly contains protective fungicide and systemic fungicide.
The representative products of protective fungicide has mancozeb, Carbatene, tpn, Kocide SD etc.After protective fungicide is applied in plant surface; contact the first infection processs of prevention with germ by residual activity and reach the purpose of preventing and treating disease; though fungicidal spectrum is wide; be difficult for developing immunity to drugs; but can only before taking place, disease use; invalid to the pathogen in the invaded plants body, can not play effective protective effect to newborn branches and leaves.
Systemic fungicide refers to and can be entered plant corpus by the leaf of plant, stem, root absorption, and in plant corpus transporting to the bactericide of site of action.This class medicament can protective plant cambium, has overcome protective fungicide and can only prevent the shortcoming that can not treat and root out.The systemic fungicide of control oomycetes disease can be divided into following a few class: phenyl amide series bactericidal agent, ethanamide bactericide, carboxylic acid amide series bactericidal agent, QoI ' s series bactericidal agent, 2,6-dinitroaniline series bactericidal agent, carbamate fungicide, benzamide series bactericidal agent, imidazoles bactericide.
In producing at present because the unreasonable use of bactericide, as frequently using with a kind of bactericide for a long time, arbitrarily strengthening incorrect operations such as medicament usage amount, fruits and vegetables oomycetes disease reproduction speed is fast in addition, the characteristics that season of growth can be circulated and be infected, caused fruits and vegetables oomycetes disease that medicament is developed immunity to drugs, control efficiency descends, and therefore is badly in need of exploitation new bactericide or bactericide compounded product at present.
Carbatene is a kind of multidigit point protection bactericide; belong to low-toxin farm chemicals; wide, the difficult resistance that produces of its bactericidal range; control efficiency obviously is better than other same series bactericidal agents; be mainly used in control fruits and vegetables oomycetes disease, anthracnose, brown spot etc., and can be used for preventing and treating crop pest with the systemic fungicide spraying that is mixed.Consulting present related data and document does not see as yet to have carboxylic acid amide series bactericidal agent and Carbatene is combined into the research report that composite bactericide is used to prevent and treat fruits and vegetables oomycetes disease.
