Description
Technical field
The invention belongs to the disinfectant use in agriculture field, relate to a kind of preparation and application that contains the bactericidal composition of Enestroburin.
Background technology
Enestroburin (enostroburin), molecular formula: C
22H
27ClNO
4, chemical name: α-[[[[4-(4-chlorphenyl)-Ding-3-alkene-2-base-] imido grpup] methyl] phenyl-'beta '-methoxy acrylic acid methyl esters.
Enestroburin class wide-spectrum bactericide is a class novel agrochemical of successfully developing as the bactericide lead compound from natural products Strobilurins, belongs to methoxy acrylic bactericide.The action principle of this type of medicament is to suppress the mitochondrial breathing of fungi, the Q0 position by cytochrome b c1 complex in conjunction with suppressing mitochondrial current potential transmission, the germ energy is synthetic to play bactericidal action thereby destroy.Characteristics such as having efficient, wide spectrum, protection, treat, root out, infiltration, systemic activity, resistance of rainwater washing against, lasting period are long.To 1,4-demethylation enzyme inhibitor, benzamides, the bacterial strain of dicarboxyl amine and benzimidazole generation resistance is effective, does not have cross resistance with at present existing bactericide.Nearly all Mycophytes (Ascomycetes, Basidiomycetes, Oomycete and Fungi Imperfecti) disease such as powdery mildew, rust, Ying's rot, net blotch, downy mildew, rice blast etc. all there is good activity.Except that downy mildew, eqpidemic disease are had the special efficacy, rust, powdery mildew, anthracnose, rice blast, damping off, scab all there is good activity.To crop safety, because of its at soil, capable of being fast degraded in the water, so environmentally safe.
The agent of Enestroburin list is used for a long time, and disease is developed immunity to drugs, and causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.And that the active ingredient of the different mechanisms of action is carried out is composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.
